摘要：In a Mobile Wireless Sensor Network (MWSN), mobile sensor nodes move freely at the network environment. So, a large number of attacks threaten this network. Unauthenticated broadcast attack is a common attack which worsens the network congestion as well as energy consumption. In this paper, an efficient method for defending unauthenticated broadcast ATTAcks, AT2A, in MWSN has been proposed. AT2A method keeps sending history of each node in transmission table of nodes to make decision about each incoming packet, i.e., packet should be dropped or forwarded. After receiving a new packet in each node, AT2Amethod forwards the packet with probability of 1-p, i.e.,AT2Amethod detects unauthenticated packet and drops it with probability of p. Indeed, AT2Amethod does not process incoming packets for unauthenticated packet detection; rather AT2Amethod considers sender node behavior to packet drop/forward. Simulation results which have been implemented using NS-2 simulator show thatAT2Amethod detects 98% unauthenticated packets by three nodes while it increases filtering efficiency compared with previous methods
