In order to solve the problem of multi-sinks and multi-sources routing in wireless sensor networks(WSNs)
a net model based on Anycast is proposed
and the energy consumption and network lifetime problems are studied.Topology
energy and path selection model of WSNs are respectively built.Type of data packets is regulated and a routing protocol based on Anycast is proposed.Simulation experiment show that this model can effectively share load of the network compared with LEACH protocol.When the number of nodes is up to 100
the number of base station increases from 3 to 6
and energy consumption of network decreases by 33.3 %
and the network lifetime is prolonged accordingly.
