Abstract: In wireless sensor network, sensor nodes have limited power back-up. So, the main issue is to increase the network lifetime. The multi-chain 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 shown satisfactory.
Keywords: multi-chain PEGASIS, revised MIEEPB, sink mobility, energy efficient
1. Introduction
In many application areas, the wireless sensor network must be able to operate for long periods of time, and the energy consumption of both individual sensor nodes and the sensor network as a whole is most important. Thus energy consumption is an important issue for wireless sensor networks. Figure 1 shows the architecture of wireless sensor network. It consists of one sink node (or base station) and a (large) number of sensor nodes deployed over a…
