Sink Mobility-aware Node Scheduling algorithm for Wireless Sensor Network

Abstract

In application base environment using Wireless Sensor Network (WSNs), mobility sink and node plays a key role in concern with topological changes affecting on the bandwidth utilization, energy consumption and delay. Due to the scarcity of available resources, it demands the solution with a better reduction in delay and energy consumption for increased slot utilization and reduced collisions. The paper proposes Sink Mobility-aware Node Scheduling algorithm (SMNS) using TDMA as basic MAC. Slots are scheduled to reduce glitches and offset occurring in switching the data from nodes to movable sink in clustered environment. The collision-free slots allocated shows reduced energy consumption and delay as compared to state-of-the-art solutions.
