Performance Analysis of SEP and LEACH for Heterogeneous Wireless Sensor Networks
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2014, Vol 10, Issue 4
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 in which the relation between number of alive node and number of rounds for different base stations and terrain area is analyzed. If the base station is closer to the network nodes die out after more number of rounds when compared to the base station far from the network. For larger terrain area nodes die out after more number of rounds when compared to the smaller terrain area.
