“…In this figure, the ratio of the locatable nodes for basic DV-HOP algorithm and the improved DV-HOP algorithm are reduced when improvement for the percentage of attacked beacon nodes.The percentage of the located node improved is higher than the basic DV-HOP algorithm in the same case where the percentage of attacked beacon nodes is same.More proportion of malicious beacon node increase around the Node,unknown location,as augment for proportion of the attacked node.Position coordinates information produce large error in the process of node localization.Malicious nodes are eliminated by credibility of the beacon node through the improved DV-HOP algorithm. Therefore,the ratios of the referred beacon nodes and located node are descended.However, the accuracy of node being unknown location is stable.At last, under the condition of the mobile beacon nodes, the situation will become more complex, therefore algorithms need to be further improved [16]. algorithm in network positioning coverage and location error.…”

Abstract. The secure location of node is significant in the WSN (Wireless Sensor Networks) of the troop frontier defence system. The wormhole attack is a big threat in the secure location. The credibility of the beacon node was used to determine the malicious nodes produced by wormhole attack in the WSN. The estimated method of multibeacon nodes was adopted to improve DV-HOP algorithm after excluding the malicious nodes.In this paper,we compared the basic DV-HOP algorithm and the improved DV-HOP algorithm in the coverage percentage and the error of network localization by simulating. The simulation results indicate that the improved DV-HOP algorithm makes the localization coverage percentage can reach 90% on a certain scale of the network,andit makes the error percentage lower when the number of beacons is different.
