The invention relates to a random sleep scheduling routing method for wireless sensor networks, which belongs to wireless network protocols. The concrete method is that each node maintains a pseudo random number sequence. The sequence is generated by randomly generating seeds of each node by the same pseudo random number generation algorithm. Then, the node determines the random sleeping schedule in the running period of the network by the random number sequence. When we broadcast our own seeds in the network initialization, the nodes and their neighbors can learn the pseudo random sequence of each other by computing, so as to know the sleep and recovery time of each other. When a node needs to send data, it sends the packet to the first awakened node by calculating the recovery time of its neighbors. This mechanism enables the node rotation work through a random sleep scheduling mechanism, in order to achieve the objective to reduce and balance the energy consumption of the whole network.

无线传感器网络的随机休眠调度路由方法，其特征在于：各个节点维护一个伪随机数序列，该数列是以各节点随机产生的种子由同一个伪随机数生成算法生成的；继而，节点以该随机数序列确定出自己在该次网络运行周期里的随机休眠时序安排，通过在网络初始化时广播自己的种子，节点与其一跳邻居可以通过计算获知彼此的伪随机数列，从而得知彼此的休眠与苏醒时间；当节点需要发送数据时，通过计算自己邻居的苏醒时间，将数据包发送给第一个醒来的节点。
