many performance evaluations for ieee 802.11distributed coordination function (dcf) have been previouslyreported in the literature. some of them have clearly indicatedthat 802.11 mac protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. although rts/cts transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...

In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

In recent years, routing has been the most focused area in ad hoc networks research. On-demand routing in particular, is widely developed in bandwidth constrained mobile wireless ad hoc networks because of its effectiveness and efficiency. Most proposed on-demand routing protocols are built and relied on single route for each data session. Whenever there is a link disconnection on the active ro...
