The node's energy of wireless sensor networks is limited, so saving energy and prolonging network's lifetime is very important. A multi-hop routing protocol based on grid optimization (MhRPGO) is proposed to improve network's performance in wireless sensor networks. The clustering topology based on grid is used in the network layer, and grid optimization algorithm is adopted to optimize the node's...
In wireless sensor network, it is essential to find effective means for power control of randomly distributed nodes. In this paper, based on diverse receiving QoS parameters, a fuzzy algorithm for peer to peer power control of wireless sensor nodes is proposed. Simulation results show that the proposed algorithm reduces packet error rate (PER) and prolongs survival time of network, compared with fixed...
