摘　　要：为了降低节点间广播消息产生的冲突,文中提出一种基于多跳路由的无线传感器网络环境中的公平性策略,使得簇内节点在向簇首转发数据包时,可以采用一种更为公平的方式竞争信道,各层节点根据自己的权值大小获得发送数据包权限后在下一轮进入休眠状态,在保证公平性的同时有效节省监听时耗费的能量,达到提高网络生命周期的目的.In order to reduce the collision of broadcasting message between all nodes, this paper presented a fair competition strategy for the multi-hop routing wireless sensor networks. The nodes in the clusters sending packets to the cluster headers would be more fair in competiting the channels. They obtained permission to send data packets according to their own weights, and would go into hibernation in the next round, this method can save the energy in detection effectively to achieve the purpose of improving the network life time.
