Recognition on key node of encrypt wireless network based on OSPF protocol

Hot point recognition algorithm is designed in this paper. It is used to work out recognition of hot point in some encrypt wireless network based on OSPF protocol. We use traffic relevance to descript the character of hot point area. We recognize the area of hot point by means of calculating covariance of different reconnaissance nodes flux. Then we design the hot point recognition algorithm. Simulation results got in the NS2 show that this algorithm is well performed in hot point recognition.
