An Improved LEACH Cluster Routing Algorithm for the Differential Services

An improved PDSL cluster routing algorithm based on LEACH protocol is put forward, by which data owing different priority are provided for differential services and the cluster routing of LEACH protocol is optimized. By making cluster head nodes dynamically select single-hop routing or multi-hop routing, the consumption of network energy is balanced. Simulation result shows that life cycle of PDSL cluster routing algorithm is longer than that of LEACH, and life cycle is increased 11% and network robustness is promoted 1.4% than that of LEACH.
