Based on WSN the Largest Remaining Energy QoS Multicast Routing Algorithm

In allusion to the network characteristic of wireless sensor network and QoS constraints, such as, surplus energy of nodes, time lapse, time lapse wobble, bandwidth and so on. This paper take the maximal surplus energy for the first measurement, simultaneity considering the factors including bandwidth of nodes, time lapse, time lapse wobble and so on, has brought forward multi-QoS constrained multicast route algorithm SEQMRA-W based on maximal nodes' surplus energy, the algorithmic realization process and the step is given, and carry through the certification of algorithmic validity and the analysis of complexity. The experiment indicated that the algorithm in the route success rate, cost of multicast tree. Energy consumption has fairly good characteristic.
