This paper focus on multi hop mobility management in WSN ad hoc Network using DVS algorithm for minimum energy consumption. To improve cross layer collaborative in wireless sensor network as well as to improve processing capacity according requirement. In WSN, senor do not only process information at application layer but also synchronize their communication. Using our propose architecture containing two main phases Multihop task mapping and Multihop scheduling using DVS for minimum energy consumption in WSN ad hoc network. Simulation result show significant performance improvement compared with existing mechanism in term of multihope data transfer in NS2.
Cloud Computing, being in its infancy in the field of research has attracted lots of research communities in last few years. Lot of investment is made in cloud based research by MNCs like Amazon, IBM and different R & D organizations. Inspite of these the number of stakeholders actually using cloud services is limited. The main hindrance to the wide adoption of cloud Technology is feeling of insecurity regarding storage of data in cloud, absence of reliance and comprehensive access control mechanism. To overcome it, cloud service providers have employed different security mechanism to protect confidentiality and integrity of data in cloud. We have used PAVD security system to protect confidentiality and integrity of data stored in cloud. PAVD is an acronym for Privacy, Authentication and Verification of data. We have statistically analyzed the performance of PAVD security system over different sizes of data files. This paper aimed at comparing the performance of different cloud storage services like Drop box, sky drive etc with our PAVD security system with respect to uploading and downloading time.
This paper based on research related Ad hoc networks does not rely on dedicated network devices. It relay or route messages f rom a source to a destination. As there is no global coordinator, nodes have to organize themselves to avoid scalability issues that may arise when the size of the network is growing. Virtual backbones, by selecting a subset of network nodes and / or communication channels, ar e a set of techniques mimicking the infrastructure in the classical network paradigm. Ad hoc virtual backbones however are not composed of dedicated devices but from regular network nodes which were selected to help relaying messages. The connected dominating s et (CDS) has been extensively used for routing and broadcast in wireless ad hoc networks. While existing CDS protocols are successful in constr ucting CDS of small size, they either require localized information beyond immediate neighbours, lack the mechanism to properly handle nodal mobility, or involve lengthy recovery procedure when CDS becomes corrupted.
Mobile Ad hoc Network is a collection of mobile nodes in which the wireless links are frequently broken down due to mobility and dynamic infrastructure. Routing is a significant issue and challenge in ad hoc networks. In Mobile ad hoc network, due to mobility of nodes network topology change frequently and thus, routing become challenging task to transfer the data from source to destination. A variety of routing protocols with varying network conditions are analyzed to find an optimized route from a source to some destination. This paper is based on performance comparison of two popular mobile ad-hoc network routing protocols using simulator i.e. DSR, ADOV. On the network simulation platform, a systematically simulation and research has been carried out on the performance of two routing protocols, and how the network environments impact on the performance of routing protocol.
