The development of wireless technologies has been stimulated by the ever increasing network capacity and the diversity of users’ quality of service (QoS) requirements. It is widely anticipated that next-generation wireless networks should be capable of integrating wireless networks with various network architectures and wireless access technologies to provide diverse high-quality ubiquitous wir...

There are large varieties of applications of wireless sensor networks. The two major applications of the wireless sensor network are tracking based and second is monitoring based. There are sensors which communicate with each other to form a network. In the wireless sensor network there are number of issues which affects the performance and efficiency of the wireless sensor network. This paper ...

Due to the failure-prone and vulnerable structure of WSN nodes, understanding typical activity patterns nodes helps identify faulty malicious node activities, differentiate normal behaviors from abnormal behaviors. In this study, for we observe effects network load on energy consumption, packet throughput, latency parameters. We run simulations networks with a variable number sinks. found that ...

The Wireless Sensor Network (WSN) technology is being used in a huge number of monitoring applications. It consists large sensor nodes with limited battery life. These devices are deployed randomly zone to collect the data. But these threatened and attacked by several malicious behaviors caused some nodes, which result security attacks. Several attacks occur different layers wireless network. D...

In today’s technology, the essential property for wireless communication network is to exhibit as a dependable network. The dependability network incorporates the property like availability, reliability and survivability. Although these factors are well taken care by protocol for wired network, still there exists huge lack of efficacy for wireless network. Further, the wireless access network i...
