Rendezvous Nodes (RN Nodes) Based Cluster Head Selection and Energy Efficient Data Aggregation with Mobile Sink for Lifetime Maximization in Wireless Sensor Networks

04/20/2020 ∙ by Rajat Pushkarna, et al. ∙ 0

Wireless sensor network (WSN) consists of a group of dedicated sensors nodes which are distributed over a certain area for observing and recording the physical conditions (like temperature, sound, pressure) of the environment and organizing the collected data at a central location. These Sensor nodes are powered by a battery, so energy conservation becomes an important aspect in WSN. The Paper proposes a way of combining traditional LEACH (Low Energy Adaptive Clustering Hierarchy) with Mobile Sink and Rendezvous Nodes (RN Nodes) along with some changes in terms of cluster head selection process. The paper aims at decreasing the number of dead nodes which in turn will relate to a increase in the total network lifetime. Particularly for large regions the proposed algorithms outperforms traditional Leach as proved in the Simulation Results.
