THRESHOLD SENSITIVE ADVANCED DEEC ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORKS (WSNS)

Abstract

Wireless Sensor Network (WSN) is a kind of self-configuring network composed of a set of wireless sensor nodes (also called motes). The lifetime of WSN is limited because the sensor node works on battery life and it is hard to recharge the battery at regular basis because of the deployment of wireless sensor network in remote and hostile places. In order to prolong the network lifetime, a network routing protocol with high energy efficiency is necessary besides designing low-power sensor nodes. In Wireless sensor networks, several routing protocols have been developed to improve the various parameters such as stability period, throughput etc. Several Homogenous and heterogeneous Routing protocols were discovered in the domain of Wireless sensor networks. The homogenous network has all nodes of same energy and heterogeneous has nodes of different energies. But studies have shown that heterogeneous protocols are better to prolong the lifetime of the network. A clustering based homogenous protocol Low energy adaptive Clustering hierarchical (LEACH) gave a basic clustering approach to make efficient protocol for routing. After this many heterogeneous protocols were explored which successfully improved the throughput, lifetime etc of wireless sensor network. In this research the heterogeneous protocol, Distributed Energy efficient Clustering(DEEC),its enhanced Version EhancedDEEC(EDEEC) and their further improvements have been explored and have made them more efficient further by advanced distributed energy efficient clustering (DEEC) routing protocol for wireless sensor new node superadvanced node in addition to normal, advanced and super nodes as in EDEEC is taken to increase the stability period and longevity of the network. As energy cost is more in term of transmission of data than processing data in the nodes, so to optimize the transmission, reactive routing protocol TEEN is applied in this research. This saves a lot of energy and makes transmission better in terms of throughput, longevity of the network etc. This research has been simulated in matlab and successfully outperformed the LEACH, DEEC and EDEEC in terms of alive nodes, dead nodes and throughput.
