| 摘 要： | 分析无线传感器网络中各个节点位置上的数据及能量负载，提出一种新的非均匀部署策略，在网络中均匀部署满足监测需要的工作节点，但在近sink区域部署更多不感知数据，只转发数据的中继节点，以实现网络的能量消耗均衡，并分析传感器节点最优传输半径优化问题。实验结果表明，该策略能够有效降低网络能耗，延长网络寿命。

| Abstract: | The data and energy load of each position in Wireless Sensor Network(WSN) is analyzed. A novel nonuniform node distribution strategy is proposed, whose core is uniformly deploying working sensors which can satisfy the demand of monitoring in all the place of the network and more relay sensors in the place closer to the sink. These relay sensors just transmit data but not generate data. The setting of the optimal transmission radius is analyzed. Experimental results show this strategy can not only debase energy depletion but make the network lifetime extended. |
