In wireless ad hoc networks with stationary and portable nodules situation, planning a backoff procedure is decisive to evade impact and to increase the act of nodules. Majority of the Medium Access Control (MAC) etiquettes intended for ad hoc networks take up stationary nodules situation. In this paper, an Optimized Adaptive Backoff Algorithm (OABA) is proposed for static and mobile wireless ad hoc networks. In this algorithm, during the back off stage, the type of node is determined as static or mobile. For mobile nodes, their residence time is determined in addition to their priority. Then optimized adaptive backoff algorithm is applied, by checking the type of node. Simulation results have shown that OABA achieves higher delivery ratio with minimized delay, packet drop and energy consumption.
