Performance Analysis on Homogeneous and Heterogeneous Routing Protocols in Wireless Sensor Networks

Wireless Sensor Network (WSN) is made up of distributed sensor nodes that are liable for perceiving the physical or environmental conditions; however, there are a few downsides to this network, e.g. the network is prone to failure, the sensor nodes have limited power and capacity and may not have global identification. Specialists have devised several routing strategies based on route processing, network structure, and network operations to expand a variety of applications for this network. Among all these, the hierarchical routing protocols along with clustering methods can expand the life span and efficiency of the network. Furthermore, clustering can be done in homogeneous and heterogeneous ways. The comparative study of homogeneous and heterogeneous LEACH, EAMMH, and TEEN routings in terms of average energy, alive nodes, dead nodes, throughput, stability period, and network lifetime are investigated in this work by using MATLAB simulator. The results enumerate that heterogeneous TEEN has better performance than other routings in terms of all the considered metrics.
