Abstract
Energy conservation in Wireless Sensor Networks (WSN) is a key research area because sensors are energy-constrained devices. Sensor energy saving in the large and harsh geographical environment is a major challenge in WSN. This paper presents novel strategies for enhancing energy efficiency in routing and data collection, employing clustering techniques and mobile sinks to address this challenge. The sensing area is considered a circular shape and divided into blocks. The blocks are formed by dividing the circular area into concentric circles and dividing sector lines to form unequal blocks. Based on the block node centroid, the block head is selected. The block and block head are similar to the cluster and cluster head respectively. Two mobile base stations (MBS) are used to collect block head data. Two MBS move with a predefined path with constant speed and halt at sojourn points to collect data from the blockheads. After collecting data, it transfers data to the gateway nodes or base station. In simulation results, the mobile node-based scenario outperforms the centralized base station and static block heads communication. The proposed work is also compared with existing works and this scheme shows a 21% improvement in network life and end-to-end delay.
