Performance And Reliability Improvement Model For WSN

The wide utilization of Wireless Sensor Networks (WSNs) is obstructed by the severely limited energy constraints of the individual sensor nodes. This is the reason why a large part of the research in WSNs focuses on the development of energy efficient routing protocols. Energy conservation is one of the major important issues in wireless sensor networks. In WSN communication is based on battery operated computing and sensing devices. In WSN sensor networks energy to be deployed in an Adhoc manner, with a positive approach, individual nodes can be largely inactive at idle periods of time, but when something is detected then becoming suddenly active. In WSN the major challenges for research are conservation of energy and security. Large-scale deployments will require routing protocols that scale to large network sizes in an energy-efficient way. Routing in WSNs is very challenging due to unique inherent characteristics (energy efficiency and awareness, connection maintenance, minimum resource usage limitation, low latency, load balancing in terms of energy used by sensor nodes, etc.) that distinguish this network from other wireless networks such as mobile ad hoc networks, cellular networks, and wireless mesh networks. This paper presents existing issues of WSN which can affect its performance and reliability and also proposed a reliability and performance improvement model for WSN.
