Asymmetric RTS/CTS in Ad Hoc Wireless LAN

Abstract — A wireless network node with the Omni antenna tends to cause problems called “Hidden Node ” and “Exposed Node”. RTS/CTS mechanism has been introduced to mitigate Hidden Node and most of existing researches assume that RTS and CTS are sent at the same data rate. In this paper we have intentionally allocate different transmission rate to RTS and CTS in order to mitigate effect of Exposed Node. The simulation result showed that the proposed method achieved higher throughput
