Analyzing the heterogeneous and homogeneous WSNS in the term of total energy consumption

Abstract EN

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 Stable Election Protocol (SEP-E), in term of total energy consumption as a heterogeneous networks.

Based on the calculation of total energy for such protocols new equations are derived to calculate the average energy for each protocol.

A homogeneous network with same parameters of SEP and SEP-E, equal number 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 networks with the proposal homogeneous network.

The results showed that the performance of proposed network is out performed each SEP and SEP-E by relative amount of rounds.

On the other hand, the extra amount of total energy of heterogeneous networks is assumed as extra number of nodes for proposed network.

The extra nodes are assumed as sleeping nodes for such network and simulation is applied.

The results confirmed that relative improvements are obtained in the stable period of new network.

In addition to the relative improvements, another benefit is to get rid of the limitations imposed by heterogeneous network like immobile nodes which give more flexibility for homogeneous network
