Abstract

Cooperative networking brings performance improvement to most of the issues in wireless networks, such as fading or delay due to slow stations. However, due to cooperation when data is relayed via other nodes, there network is more prone to attacks. Since, channel access is very important for cooperation, most of the attacks happens at MAC. One of the most critical attack is denial of service, which is reason of cooperation failure. Therefore, the cooperative network as well as simple wireless LAN must be defensive against DOS attacks. In this article we analyzed all possible of DoS attacks that can happen at MAC layer of WLAN. The cooperative protocols must consider defense against these attacks. This article also provided survey of available solutions to these attacks. At the end it described its damages and cost as well as how to handle these attacks while devising cooperative MAC.
