Abstract
Prolonging network lifetime has become a real challenge in Mobile Wireless Sensor Networks (MWSNs) as sensors have limited energy. In this paper, we propose a Cluster-based Energy-efficient Scheme (CES) for electing a cluster-head to evenly distribute energy consumption in the overall network and therefore obtain a longer network lifetime. In CES, each sensor calculates its weight based on k-density, residual energy and mobility and then broadcasts it to its 2-hop neighborhood. The sensor node with the greatest weight in its 2- hop neighborhood will become the cluster-head and its neighboring sensors will then join it. We performed simulations to illustrate the effects of sensor mobility on LEACH and LEACH-C’s performance. Unfortunately, our findings showed that sensor mobility had a significant impact on both protocols’ performance, but CES provided good results in terms of the amount of data packets received at the sink when compared with LEACH and LEACH-C.
