Abstract: Since the present algorithms are on the assumption of correct beacon information, when the network is attacked, especially the beacons are captured by opponent, all algorithms would not work. To address this issue, one protocol which does not increase the number of beacon or even do not use the beacon on the basis of the thought of validation node SLPDVNM which can realize localization by dynamic validation node combining some kind of localization algorithm mechanism was presented. Secure analysis and simulation of protocol performance based on MMSE localization algorithm show that the proposed protocol not only can overcome the infection of vicious beacon but also has good resistance ability against some known attack.
