Spatial-Community Resource Discovery Based on Spherical Migration in Mobile P2P Network

Aiming at how to reduce energy consumption and improve the node survival cycle in mobile P2P network, SRDBSM was proposed. It uses the transmission characteristics of spatial node to search the optimal node which is considered as next-hop node within the maximum effective transmission range. It's not only reduces next-hop number and communion time, but also improves the efficiency of resource discovery. Theory analysis and experiments indicated that SRDBSM can improve some aspects including reducing node energy consumption; prolonging the network survival cycle and increasing the efficiency of resource discovery compared with Random Walk and Modified-BFS.
