A position-based chain cluster routing protocol for strip wireless sensor network

Abstract

In some Wireless sensor network application the nodes have to be deployed in a narrow strip area and the traditional routing algorithms can not be directly applied in such strip WSN. In the strip WSN the node near the base station has to receive and forward massive data, and are of no use after energy exhausting very quickly which will reduce survival time of the network and aggravate the "hot spot" question of the network. In order to improving communication efficiency of the strip network, a Position-based Chain Cluster routing (PCCR) protocol proposed is proposed in this paper. In PCCR protocol the strip WSN is divided into many belt-shaped region cluster which elected the cluster head through node' position and dump energy and the cluster head chain is set up as the backbones of the strip WSN to forward the data of nodes. The simulation experiment result indicated that the PCC protocol is more suitable for the strip WSN than LEACH and can prolong the life cycle of the strip WSN effectively. © 2011 Springer-Verlag Berlin Heidelberg.
