Recognized based on multi-hop wireless sensor network Select Forward Attack detection

Compares with other types network, the wireless sensor network it more vulnerable to attacks, in-depth analysis of the characteristics of various attacks,we have studied the Select Forward Attack of sensor network, propose a detection method of Select Forward Attack which is based on random testing of multi-hop point confirmed. Through the detection point of sending and receiving data packets, statistics on the number of packet loss, computing nodes trust, according to the node set threshold to determine whether the attack. Considers the network load capacity and safety, random test point determined willfully in the transmission way, avoids the fixed check point becoming the goal which the enemy captures, to ensure overall network testing capabilities, and reduces the network transmission load to save the energy as far as possible, effectively improve the robustness of sensor networks.
