Robust Localization Algorithm Research of Wireless Sensor Network

Location is a vital foundation work in Wireless Sensor Network(WSN).All location algorithms at present need the position information of beacon nodes to locate the non-beacon nodes.When the position information is affected by the attacker or errors,the accuracy of these algorithms will degrade badly.We list some attack ways and propose the trilateration algorithm TVNRP based on Von Neumann Rejection Principle(VNRP).We construct a simulation circumstance which might be attacked and compare the TVNRP with original algorithm.The experiment results demonstrate better robustness than original algorithm.
