Embodiment Construction
[0009] The present invention will be further described below in conjunction with accompanying drawings and examples.
[0010] The protocol is divided into three stages. In the first stage, local energy information exchange is completed. In the second stage, a broadcast tree is established according to the energy information obtained in the first stage. In the third stage, the broadcast source sends data according to the broadcast tree established in the second stage. The first two stages can be performed in parallel.
[0011] The implementation process of this method assumes that each node knows its neighbor nodes.
[0012] The first stage completes the exchange of local energy information. Each node diffuses its own residual energy information group to its adjacent area with period T. Each node shall hold a sequence number seq. Each remaining energy information packet carries the following information: source node id value, seq value, remaining energy value of the node, T...
