Region based low energy adaptive clustering hierarchy (R-LEACH) protocol: prolonging the lifetime of WSN

During the past few years, Wireless Sensor Networks (WSNs) have been developed massively as one of the fastest growing emerging technologies for transmitting information over the network. Nowadays, WSN is hurriedly growing its limbs in almost every sector of science and technology. The WSN composed of a vast number of small nodes that operate sensing, data collection, aggregation, compression and transmission. Due to the very narrow size of the sensor nodes, the tiny battery usually has a minimal power resource. Hence, the main challenge for WSN is to use this deficient battery power in an effective way to increase the sensor networks' lifetime and minimize energy consumption. However, numerous sophisticated clustering routing protocols have already been adopted in WSN for limiting the consumed power. The fundamental aim of this study is to elevate the Low Energy Adaptive Clustering Hierarchy (LEACH) protocol by adopting a new clustering routing topology. In our proposed model, the selection procedure of cluster heads remains the same as it had been in the ordinary Leach protocol. However, we have divided the whole area of the network over multiple rectangular distributed regions. In each region, we have applied the LEACH algorithm. In this paper, the mechanism of R-LEACH is simulated through MATLAB simulator and then the results have been analyzed.
