A Communication Model of Anycast in Wireless Sensor Networks

Anycast is a mechanism that the source node sends the data groups to the nearest sink node. The paper proposes a communication model of implementing an Anycast service for deploying several sinks in wireless sensor network. We propose a novel anycast tree-based approach to reduce the mutual interference and minimize the energy consumption. Here the nodes as the anycast node form a tree with a sink node as the root, while the height of the tree is based on the distance of the member nodes to the sink node and the residual energy of node. This paper discusses and analyzes the model deeply. The experimental data proves its validity and efficiency. Computer simulation shows that the proposed scheme reduces and balances the energy consumption among the nodes effectively, so it significantly extends the network lifetime compared to the existing schemes.
