A Data Fusing Random Detection Method in Ad Hoc Networks

An ad hoc network is a kind of wireless network without centralized administration or fixed network infrastructure, in which nodes perform routing discovery and routing maintenance in a self-organized way. Currently, many people focus on the routing protocol in ad hoc networks. But few people research how to detect the validity of the data fusing without large communication overhead. In this paper, a randomly detecting method is proposed. The main idea is using the random information to capture the attacker. One of initial packet to the behind of the fusing packet is attached. This part helps other nodes judging if the source node of the packet is legal. The simulation result shows that our method does not induce much overhead.
