A reasonable RSSI model is set up and introduced. The ratio ofRSSI ratio. Compared the received RSSI value with the calculated average RSSI value, the ratio is set as a hopcount and is saved. When the hopcount is more than 1, the calculated ratio in first phase is accumulated separately, which is used to reduce the location error significantly. The simulation experimental results show that the improved algorithm oflocalization, about 10% can be raised.【2】【篇名】Research on energysaving technology of wireless sensor network【摘要】As the wireless sensor network node battery is limited and changing battery is difficult, we did research on feasible energy conservation design technology. Paper analyzed energy consumption and the proportion of network node in work station of dormancy, data dealing, and munication and so on. Hardware circuit was promoted through power partition, signal isolation and low energy consumption chip application. Software program was optimized through state machine bined with differential pression coding. Then the purpose of extending network life can be reached. The experiment result shows that the energy conservation design can reduce the energy consumption greatly and extend the network
