In wireless sensor network, sensor nodes have limited power and processing
capability. So, the main issue is to increase the network lifetime. The multichain
concept in PEGASIS and sink mobility increases the network lifetime in wireless
sensor network. In this research paper, we have proposed a revised multi-chain PEGASIS protocol
by revising the position of the mobile sink to maximize the network lifetime. The simulation
is done in MATLAB R2008a and results are compared with MIEEPB (Mobile sink improved energy-
efficient PEGASIS-based routing protocol). Also, we have simulated revised multi-chain PEGASIS
according to standard assumptions and results are satisfactory.
Keywords: Energy efficient, Multi-chain PEGASIS, Revised MIEEPB, Sink mobility.
