ANALYZING THE HETEROGENEOUS AND HOMOGENEOUS WSNS IN THE TERM OF TOTAL ENERGY CONSUMPTION

Abstract

Energy consumption is the most important issue in the design of Wireless Sensor Networks(WSNs). This paper analyzed the performance of Stable Election Protocol (SEP) and Extension of StableElection Protocol (SEP-E), in term of total energy consumption as a heterogeneous networks. Based onthe calculation of total energy for such protocols new equations are derived to calculate the averageenergy for each protocol. A homogeneous network with same parameters of SEP and SEP-E, equalnumber of nodes and the initial value of energy is equal to the calculated average value is proposed.Simulations are applied using Matlab Package to compare the performances of heterogeneous networkswith the proposal homogeneous network. The results showed that the performance of proposed network isout performed each SEP and SEP-E by relative amount of rounds. On the other hand, the extra amount oftotal energy of heterogeneous networks is assumed as extra number of nodes for proposed network. Theextra nodes are assumed as sleeping nodes for such network and simulation is applied. The resultsconfirmed that relative improvements are obtained in the stable period of new network. In addition to therelative improvements, another benefit is to get rid of the limitations imposed by heterogeneous networklike immobile nodes which give more flexibility for homogeneous network.
