An Unequal Fan-Shaped Cluster Routing Protocol for Wireless Sensor Networks

Abstract:

A cluster-based network topology can increase the scalability and lifetime. However, the area around the Sink node forms a bottleneck zone due to heavy traffic-flow, which limits the network lifetime in WSN, the energy of the nodes closer to the sink node is depleted very quickly and the network die early, so it is important to ensure that the network energy dissipation is balanced. In this paper, an unequal fan-shaped clustering (UFC) model was proposed, which can lead to more uniform energy dissipation among the entire network, thus increasing network lifetime. The results show that UFC can lead to more uniform energy dissipation in a homogeneous network and prolong network lifetime.
