For mobile anchor node static path planning cannot accord the actual distribution of node for dynamic adjustment which result in incomplete coverage and lack of flexibility.We take advantage of the high localization accuracy and low computational complexity of AHLos algorithm.This article introduces mobile anchor nodes instead of the traditional fixed anchor nodes to improve the algorithm.Firstly,the high connectivity nodes are chosen in the network as AHLos algorithm initial anchor nodes.The initial anchor nodes are located through the method of approximate location.The mobile anchor nodes traverse all the initial nodes.The residual nodes in the network will be located by AHLos location algorithm.In addition,not every two initial anchor nodes are neighbor nodes in the process of traverse.The minimum hop path from one initial anchor node to the next one is defined as the transition path.The mobile anchor node use the transition path between two non-neighboring initial nodes to induction the next initial node.At the same time,the GPS can be shut down along the transition path.The mobile anchor nodes adjust its direction as soon as possible,once the signal of the next node is perceived.This method could both avoid the energy consumption of GPS and greatly reduce the actual distance of the mobile anchor node.The result shows that,through introduce the mobile anchor node,we can configure the information of initial anchor nodes more flexible.Meanwhile,with the use of the approximate location and the transition path,the distance and energy consumption of the mobile anchor node is greatly reduced.
