Abstract

In Wireless Sensor Network, one of the most critical issue is power consumption during routing. Various routing protocols have been proposed by the researchers to reduce the consumption of energy of sensor nodes which results in prolonging network life time. Routing protocols are classified into various categories such as Flat based routing protocol, Hierarchical based routing protocol, and location-based protocol. Chain based routing is the category of routing protocols which reduces the power consumption by connecting the nodes of the network in form of chains. PEGASIS is one of the popular chain-based energy efficient hierarchical routing protocol which prolongs the network life time by reducing energy consumption. This paper discusses the various modified versions of PEGASIS and compare them on the basis of different parameters such as criteria used for selecting chain head nodes, no. of chains formed, type of communication among BS and chain head node etc.
