Efficient routing algorithm for WPAN Mesh networks based on servers

Server Routing(SR) in high rate IEEE 802.15.5-based WPAN Mesh has redundant overhead and operations in the link state registration and route establishment stages of SR.A high-efficiency and low-delay routing algorithm(HLRA) was proposed.Two new mechanisms which are the broadcasting Link State Registration commands and decreasing the length of relay list in retransmission were introduced to improve the speed of building the route.Theoretical analysis and simulation results show that the network overhead and the average end-to-end delay were reduced in HLRA and the packet delivery ratio was almost kept unchanged.
