Abstract
-It is improving the robustness of the network topologies for WSNs. Itisdefine the terms of target selection for attacks, there are two types of attack: random and malicious. In random attacks, the attacker randomly chooses nodes in the network topology as the targets, whereas in malicious attacks, the attacker chooses the nodes with high node degrees as the targets. It is known that some types of network topologies are resistant to random attacks and some are resistant to malicious attacks. To use spatial information, a physical property associated with each node, hard to falsify, and not reliant on cryptography, as the basis for 1) detecting attacks; 2) determining the number of attackers when multiple adversaries masquerading as the same node identity; and 3) localizing multiple adversaries. It is proposed to use the spatial correlation of received signal strength (RSS) inherited from wireless nodes to detect the attacks.
