This thesis proposes a coordinated MAC protocol for wireless local area networks. Medium access layer plays an important role in better utilization of physical communication resources. This study proposes a coordinated MAC protocol which supports both asynchronous and isochronous communication over 802.11 like wireless channels. The proposed MAC protocol enables fully scheduled communication over the channel enabling quality of service over wireless channels. In addition the proposed network supports peer to peer mesh like communication where the data packets are communicated between nodes directly as opposed to the current 802.11 implementations where packets are bounced off the access points therefore appearing twice on the channel. The MAC layer developed is implemented in OPNET and comparative analysis to state of the art IEEE 802.11 MAC layer is studied both analytically and through OPNET simulations.
