Routing method of wireless sensor networks

The present invention discloses a method for routing in wireless sensor networks, which include: new power sensor nodes to obtain a network address and uplink and downlink routing path to become the network node; each network node to obtain the remaining capacity, network maintenance; network node when electric power left to become the next node, and then rebuild the network in the new node joins the network and network reconstruction process, because each node does not need to save the information network neighbor nodes, each node is responsible for the gateway and network neighbors between nodes interconnected together, and the use of path weight parameters makes it easier to assess the quality of the connection gateway for each path, so when the network changes, the gateway can generate alternative paths, and quickly selected by comparing the path weight parameters can be balanced flow distribution and optimal energy consumption of the transmission path, and the timely use node request sent to the transmission path to ensure reliable operation of the network, extend the life of the network.
