Location Algorithms Research in Wireless Sensor Network Base on Hops and Angle-Vector
In order to reduce the energy consumption and improve the accuracy of location in Wireless Sensor Networks (WSNs), two distributed location algorithms are proposed in this paper. One is a distributed algorithm based on hops (DABoH). It carries out location through sending the flood message packets initiatively to acquire the information of coordinates of anchor nodes. The other is a distributed algorithm based on angle-vector (DABoAV). It carries out location through introducing the angle of entering signal and applying the triangle cosine theorem. The former has the characteristic of less flood message packets and is applicable of a rigid energy consumption network. The latter has the characteristic of low location errors and is applicable of a network requiring high location accuracy. Simulation experiments validate the correctness and the feasibility of the algorithms. In the simulation, it is shown that the DABoAV owns higher location accuracy just as the anchor nodes density comes up to 10％. DABoH also shows a trend of higher location accuracy quickly with the increasing of anchor nodes. The characteristic of low energy consumption is shown when the two distributed location algorithms work in simulation.
