This paper proposes a new QoS-aware medium access control (MAC) protocol in mobile ad hoc networks (MANETs). This takes the unique challenges of MANETs into consideration, and works in conjunction with the location-based forwarding strategy. This novel protocol is based on the legacy IEEE 802.11, and thus can be relatively easily integrated into existing systems. It is adaptive and network-aware depending on the type and intensity of traffic, and relative mobility patterns of nodes. In addition, it makes use of the point-coordination-function (PCF) of IEEE 802.11 in a distributed fashion for the first time in multihop MANETs. Our strategy enables two-way admission control for improved performance, whereby the forwarder-node selection algorithm allows previous hop nodes to perform implicit admission control using locally available information, while a selected forwarder-node performs explicit admission control depending on its current load. Analytical results confirm the performance improvement of our strategy.
