摘要：For a continuously self-configuring, infrastructure-less network of mobile devices connected withoutwires, it is needed to learn the position of their neighbor nodes for the mobile nodes inorder to follow a well organizedcommunication. Specifically, it deals with a Mobile AdhocNETwork, where a pervasive infrastructure is not present,and the location data must be obtained through node-to-node communication. A growing number of ad hoc networkingprotocols and location-aware services too require that mobile nodes learn the position of their neighbors.However, sucha process can be easily distrubted by adversarial nodes. In absence of a priori trusted nodes, the discovery andverification of neighbour positions presents difficulties. The correctness of node locations is therefore an all-importantissue in mobile networks, and it becomes particularly challenging in the presence of adversaries aiming at harming thesystem. In these cases, it need solutions that let nodes verify the positions of their neighbors, so as to detect adversarialnodes announcing false locations. In this paper, it is presented a solution to discover the position of neighbour nodessecurely and verify the discovered positions to know whether the nodes are genuine or not through a NeighbourPosition Verification(NPV) protocol.Moreover, it is also proposed to block the adversaries incase of any attacks,thereby restricting their further access to the network.
