The Secure Localization Algorithm of SDV-HOP in Wireless Sensor Networks
Abstract: Security risks and
outside interference of the traditional DV-HOP location algorithm have also been
analyzed in detail. For its shortcomings such as low positioning accuracy,
vulnerable to wormholeattack and block attacks, a new location algorithm for
wireless sensor network security SDV-HOP is proposed. Firstly, a password-based
symmetric encryption and authentication solutions are added in the distance
vector exchange protocol to defend against masquerade attacks. In the key
agreement phase, nodes and neighbor nodes generate a key set of common for
communication through their respective key. Beacon node authentication is in
communication process of encryption and transmission. Because initial key is
distributed randomly, even if an attacker hijack a part of the node, it still
cannot infer the key the rest of keys between nodes; Second, for attacks
against the wormhole attack and blocking the safe handling , an average
hop-based distance estimation algorithm is introduced. The appropriate distance
value for each hop is selected by judging and comparing hop distance. And an
effective jump distance is obtained by using the weighted average method .So it
can avoid errors caused by wormhole attacks. Simulation experiments on Matlab
simulation platform show that the security algorithm not only has high accuracy
but also can effectively prevent and resist external attack, so the new
algorithm has high security.
