Comparative study of PEGASIS based protocols in wireless sensor netwroks

A comparative study involves comparison of protocols based on some performance parameters. It helps researchers to get insight into the different parameters in relevance with the protocols which ultimately lead the way to the further advancement in the field. As improvements in the field of Wireless Sensor Networks are taking place day by day. PEGASIS is a hierarchical chain oriented protocol for routing in WSN. In this paper, some important protocols based on PEGASIS architecture; PEGASIS, EEPB, IEEPB, PDCH, PEG-Ant, PEGASIS-PBCA, PEGASIS-IBCA, MH-PEGASIS, Multi-chain PEGASIS and Modified-PEGASIS are studied and comparison is done based on parameters which are important to consider while choosing methodology for a particular application of WSNs.
