Placing few heterogeneous nodes in wireless sensor network is an effective way to increase network lifetime and reliability.We address the deployment problem of heterogeneous wireless sensor networks.We present an algorithm to decide how many and where heterogeneous nodes should be deployed in the wireless sensor network.The core algorithm,based on the locations of all sensor nodes,can optimize placement of heterogeneous nodes in an arbitrary sensor network.Finally,the evaluation results of this algorithm a...
