Wireless networks are nowadays very popular. They are mostly based on IEEE 802.11 protocol which is known to show low performance in ad hoc networks. Also when infrastructured networks (many access points are placed) are considered, a single transmission could block many radio cells. This paper proposes Interference Aware (IA) MAC, a modified version of standard IEEE802.11. The main idea is not to set the Network Allocation Vector (NAV) on the reception of each RTS and CTS, but only when it is strictly required, i.e., when a concurrent transmission could actually destroy another transmission. To make it feasible, the paper proposes to insert some information about interference and received power levels into IEEE 802.11 control packets.
