A growing number of expert users are looking for entertaining and easy-to-understand experiences in the increasingly popular mobile gaming industry. Making ensuring these mobile games have high-quality, user-friendly software is crucial for keeping players happy and coming back for more. The subjective and sometimes vague expectations of expert users, however, are hard to evaluate. Stakeholders in the mobile gaming business are always looking for new apps to test and evaluate as they build new games. Measuring qualitative features that rely on software quality criteria can help in deploying this endeavor. Therefore, choosing the right assessment method is really critical. Two metrics, fuzzy rate and fuzzy weight, form the basis of the assessment. The assessment of a five-point fuzzy rating system requires simple inputs derived from surveys or questionnaires. Stakeholders tasked with guaranteeing suitable mobile application quality decide on fuzzy weight, which is shorthand for the relative importance of software quality factors along with priority. Stakeholders may reach this goal when they compare and contrast software quality elements and agree on their relative importance. The overall evaluation of quality will converge in the right direction with this method's help. In this paper, we provide a new usage of the Fuzzy Analytic Hierarchy Process (FAHP) to assess, for expert users in particular. The mobile game application sector may use this information to better formulate and assess fuzzy weights, which will strengthen the process of translating qualitative features into quantitative ones during mobile app development.

Fuzzy logic-based quantification of usability expectation for an m-commerce mobile application is a process of measuring the usability of a mobile application by using fuzzy logic principles. The usability of any mobile application is used to find out the user experience of the mobile application by analyzing the user's expectations and preferences. Fuzzy logic always be the optimal choice for quantification. Fuzzy logic-based quantification of usability expectation assesses the user experience of an m-commerce mobile application by taking into account the user's needs, preferences, and expectations. Usability expectation also takes into account the ability of the user to understand and interact with the application, the degree to which the application meets the user's expectations, and the overall satisfaction with the application. This process helps to identify areas of improvement, enabling the developers to make necessary changes for a better user experience. This study presents to design of a usability metric framework and then quantifies the overall usability quality of an m-commerce mobile application with the help of fuzzy logic. The proposed usability metric framework is based on the Goal-Question-Metric (GQM) approach and is intended to provide a comprehensive and systematic approach to design metrics to assess the qualitative aspect of mobile phone applications. The framework has been developed and tested in an m-commerce context and provides a set of measurable criteria to quantify m-commerce mobile applications as per standard. The results of the evaluation can then be used to improve m-commerce mobile applications and to ensure that the user experience is optimized.

Mobile games have become a popular way to pass the time, and an increasing number of new and inexperienced users are searching for enjoyable and simple-to-learn experiences. It is essential to ensure that the software of these mobile games is intuitive and of high quality in order to keep users satisfied and coming back. However, it is difficult to assess the subjective and frequently nebulous expectations of first-time users. In between the development of mobile game applications, stakeholders in the mobile game industry are continually exploring applications whose quality is measured. The deployment of this effort will be facilitated by the quantification of qualitative aspects that depend on software quality factors. Thus, it is crucial to choose the proper evaluation strategy. The evaluation is based on two parameters: fuzzy rate and fuzzy weight. The evaluation of a five-point fuzzy rating system is based on surveys or questionnaires, and it involves straightforward inputs. Fuzzy weight refers to the relative significance of software quality aspects, and it is determined by stakeholders responsible to ensure appropriate quality of mobile application, ensuring that the crisp sum is equal to one. This may be achieved when stakeholders agree on the relative significance or pairwise comparison of software quality factors and examine their relative value. This technique guarantees that the total assessment of quality converges in the correct direction. This paper presents a novel application of the Fuzzy Analytic Hierarchy Process (FAHP) that evaluates the appropriate fuzzy weight for software quality factors of mobile game applications, particularly for neophyte users. This will aid the mobile game application industry in formulating and evaluating fuzzy weights to reinforce the process that converts qualitative to quantitative aspects during mobile application development.

The quality and reliability of any software product are the most important issues because the quality of any product directly depends upon branding. When one talks about software as a product then it is a big question of how to ensure every dimension of quality aspect. This issue becomes much bigger when moved from a desktop program to a mobile application, due to the inherent limitation of mobile due to mobility. Thus there is a requirement to help quality managers by customizing a suitable software quality model (e.g., ISO-9126, ISO-25010, etc.) standard to ensure software quality, in mobile environments. This paper proposed criteria to quantify the quality of a mobile application.

Risk is inherently associated with each and every entity of this universe and software is not an exception to this fact. Risk can be anything that adversely affects the progress (during development) and success of software after deployment. It can occur due to incorrect assessment of user-requirements, fallacious estimates of overall development cost, improper project schedule, or quality specifications that are unattainable within the software-specific constraints. Though risks are involved in every phase of software development life cycle (SDLC) and it has been universally admitted that testing phase consumes significant part of SDLC. Testing phase is the most vulnerable one and poses a great threat to the acceptance as well as to the post deployment success of software. This paper presents the possible consequences of including risk management activities at the very first level of CMMI exclusively for small software industries (SSI) like start-ups. Based on these consequences a process improvement model for SSI is also proposed in this paper.

VANET is the subset of mobile ad-hoc network, with the help of this we can communicate among nearby vehicles and between vehicle and also fixed road side equipment. The aim of this study is to perform the feasibility analysis of Nakagami propagation model for vehicular ad-hoc networks in the Indian automotive network. The main purpose of this paper is to present a simulation-based study of distinct propagation model for vehicular ad-hoc networks and to find the efficient analysis using on-demand routing protocols that can be more suitable in various scenarios, particularly on highways. We have used different parameters like throughput and packet drop for comparing the AODV, DSR and TORA protocols in VANETs. The research outputs will be useful in implementing efficient architecture on the realistic highway scenario, especially for four-wheeler traffic types. It will be advantageous to avoid congestion and highway road accidents due to speeds of the traffic, and road condition.

Objectives: Main Objective of this research is towards the avoidance of Denial of Service (DoS) Attack in Mobile WiMAX. For this a secure authentication mechanism is required and we present a highly secure authentication mechanism. It gives a mutual authentication between Client and Server and the server resources would consume less. Methods/Statistical Analysis: For implementation of this secure authentication, a puzzle approach has been used wherein a puzzle is sent by Base Station to Mobile Station. Unless and until the client do not solve this puzzle, server will not verify its certificates. For the implementation of this work, NS-2 as a simulator, has been used. Where three scenario have been implemented: 1) normal current working scenario of Mobile WiMAX, 2) DoS attack have been simulated without puzzle approach and 3) when under DoS attack with puzzle approach implementation. Findings: The proposed puzzle approach shows an increase of overall throughput of network as compared to the existing report and also the number of secure packets are increasing. It is because of the probability of unauthenticated user becomes almost negligible. Application/Improvements: This research work can be helpful in any of the working environment where security is the most important concern as in the case of defense where availability of network and security of network is always at the highest priority.

An existing approach “FFRDV” performs well without consideration of high speed vehicles in the traffic i.e. comparatively higher speed vehicles wrt speed of Current Ferry (CF) are not available in the network and all nearby vehicles are considered as of same category. In this research paper, a new idea for selection of a proper ferry to forward the information is developed which takes into account the type of ferries & current speed of ferries and is based on fastest ferry. The election for highest speed ferry during variable size blocks take it towards robustness to handover high speed vehicles which minimize one-way delay and maximize PDF. This may be used to prevent the accidents and to call emergency services. The advantage of proposed algorithm over existing approaches is validated by the results obtained by MATLAB. The proposed scheme minimizes the end-to-end delay and thus a message can be arrive at destination early which in turn saves many accidents and thus saves lives and money.

Software measures play an eminent role in the evaluation of quality of a Web-based application. Increased dependency on Web-based applications enhanced the need to evaluate Web quality parameters. A poor quality Web application fails to fulfill customer's implicit and explicit requirements resulting in poor customer acceptance. Many frameworks have so far been proposed for measurement of quality parameters of Web-based applications but they lack in one way or other. Most of the existing frameworks deal with narrow range of quality characteristics or is limited to a specific Web-based application perspective. Based on the limitations of the current frameworks, this paper proposes a new generic conceptual object-oriented framework multi-attribute quality model which scientifically categorize quality characteristics and its sub-characteristics based on different perspectives and usage of Web applications. The main concept of the newly proposed framework is to analyze and expand the previously established quality characteristics in Web-based applications. The approach is chosen due to the diverse and impulsive nature of the Web applications. For designing the framework ISO/IEC 9126 framework is used as reference.

During the routing, Data is collected from the all sensor nodes, in result, the sensor nodes located closer to sink node have to receive and transmit not only their own data but also data from other sensor nodes, which are further sent to sink. It leads to the fact that the nearest sensor nodes fail much earlier than remote ones, In the long run, traffic from all the sensor nodes is going through one sensor node that is nearest to sink and the former disrupt the work of the rest of WSN. From the point of view of energy saving, big WSNs with only one sink cannot consume resources effectively. To solve this problem it is necessary to divide the WSN into clusters. The new algorithms proposed with the name of Predictive packet reception with energy (PPRE) with the focus of cluster formation and data transfer used in wireless sensor networks by using soft computing techniques. The proposed algorithm would improve the quality of data transfer in a granted way through by increasing the overall packet delivery fraction, throughput, stability of whole networks. The proposed scheme is simulated over NS 2.34 and MATLAB.

Multilevel feedback queue scheduler suffers from major issues of scheduling such as starvation for long tasks, fixed number of queues, and static length of time quantum in each queue. These factors directly affect the performance of the scheduler. At many times impreciseness exists in attributes of tasks which make the performance even worse. In this paper, our intent is to improve the performance by providing a solution to these issues. We design a multilevel feedback queue scheduler using a vague set which we call as VMLFQ scheduler. VMLFQ scheduler intelligently handles the impreciseness and defines the optimum number of queues as well as the optimal size of time quantum for each queue. It also resolves the problem of starvation. This paper simulates and analyzes the performance of VMLFQ scheduler with the other multilevel feedback queue techniques using MatLab.

In multilevel feedback queue scheduling algorithm the major concern is to improve the turnaround time by keeping the system responsive to the user. Presence of vagueness in a system can further affect these performance metrics. With this intent, we attempt to propose a fuzzy based multilevel feedback queue scheduler which deals with the vagueness of parameters associated with tasks as well as to improve the performance of system by reducing the waiting time, response time, turnaround time and normalized turnaround time. Performance analysis shows that our methodology performs better than the multilevel feedback scheduling approach.

4G is based on two core technologies LTE (Long-Term Evaluation) and Mobile WiMAX (Worldwide Interoperability for Microwave Access). LTE and WiMAX system architectures are optimized for packet data to support the increasing amounts of data traffic. Compared with existing wide area cellular system's architectures, WiMAX and LTE provides improved respond time and reliability both are based on IP backbone. But when a technology comes, threats also comes with it like DoS, Man-in-Middle, Jamming as mentioned in the previous section. These threats occur at different layers of WiMAX like Jamming at Physical layer, DoS at MAC layer. This paper reviews about these different attacks and their effect on WiMAX. It has been analyzed that still initial phase is quite insecure because messages transmission is unencrypted. Initial phase can be more secure if an encrypted puzzle is transmitted from Base Station to Subscriber. And Subscriber would be supposed to solve this puzzle before consuming resources of Base Station.
