1 Abstract — The collaborative and low-cost nature of wireless sensor networks brings significant advantages over traditional communication technologies, making them a vital component of the next generation of transport systems, the smart transport grid. In this paper, we explore the implementation of a smart monitoring system over a wireless sensor network. We analyze the opportunities and challenges for distributed signal processing in networks of these sensing elements and investigate some of the architectural challenges posed by systems that are massively distributed, physically-coupled, wirelessly networked, and energy limited. The article is considered an example of the analysis of an actual transport system.
Ontology provides means to describe concepts effectively. It has become an increasingly useful tool in understanding concepts in various fields of information systems and technology. The aim of this paper is to build and evaluate an ontology that standardizes concepts and semantics of the product quality attributes in requirements engineering, in order to provide a common understanding of those concepts among software engineers. This ontology leads to easy learning of quality attributes concepts for new system developers. Dependability and efficiency are the two quality attributes that have been selected. All resources have been converted to text format. This paper reflects the results of this experiment. The main contributions of this paper are building domain ontology for quality attributes dependability and efficiency and defining relevancy measure to check the quality of resource knowledge and ontology.
In this paper, an e-voting scheme is presented. The proposed scheme can make interaction between electors and e-processes with the least possible number of protocols. The proposed scheme let easy ballot casting and rapid counting for e-users. The scheme merges two signature schemes, blind signature and short signature. The signatures utilize pairing-typed scheme with the secure hash function. The scheme produces votes contain only two messages, one blind signature and one short signature. We show that the result of the proposed scheme is more efficient than already exited e-voting schemes those using the integer factoring and discrete logarithm. The implementation calculates the entire scheme in ≈ 6.17ms . The Laptop used an Intel, Core i7-2600K CPU @ 3.4 GHz, and 8GB of RAM.
Overbuying due to store offers is a common problem in all societies; people tend to overbuy, thinking that saves them more money, but end up wasting most of it. In this paper, we present a system to solve this problem. The system allows users to post a deal they want to share with others, allowing interested users to find someone willing to share the deal with them. This system aims to help society consume more rationally, as well as to help those who want to save up money to get the best deals out of shopping.
