A distributed self-organizing clustering routing protocal for wireless sensor networks

Aimed at the inapplicability of LEACH protocol for large-scale sensor network and uneven energy consumption, a Distributed Self-organizing Clustering Routing protocol (DSCR) for large-scale sensor network is proposed. Based on clustering, the network routing is divided into two levels: parent cluster and cluster. The cluster structure is formed by the back-off mechanism related to the residual energy. The cluster head organizes the member nodes to transfer the data to cluster heads by multi-hop routing in their respective TDMA slots. The data between the cluster heads are aggregated and uploaded to the parent cluster to form the parent cluster structure. The simulation results show that compared with the LEACH protocol, the routing protocol is completely self-organizing and is suitable for large-scale sensor network, and the energy consumption of each location in sensor filed is even, which effectively prolongs the lifetime of the network and improves service quality.
