Performance Analysis of Stable Election Protocol for Clustered Heterogeneous Wireless Sensor Networks

Abstract

While wireless sensor networks are increasingly equipped to handle more complicated functions, these battery powered
sensors which used in network processing, use their constrained energy to enhance the lifetime of the network especially in a heterogeneous settings. Clustered techniques have since been employed to optimize energy consumption in this energy constrained wireless sensor networks. In Classical clustering protocols, equal energy is assigned to all nodes and
they cannot take full benefit of the presence of node heterogeneity. SEP, a heterogeneous-aware protocol is used to prolong the time interval before the death of the first node which is crucial for many applications where the feedback from
the sensor network must be reliable. The performance of SEP in comparison to LEACH Protocol is analyzed in this paper
whose goal is to increase the stable region and as a result decrease the unstable region and improve the quality of the
feedback of wireless sensor network, in presence of heterogeneous nodes.
