Achieving quality of service (QoS) in IEEE 802.16 networks depends, among other factors, on mechanisms for traffic policing at the base station (BS) and subscriber stations (SSs). Since IEEE 802.16 does not include a mandatory policing, this paper proposes a policing mechanism for the SS in the uplink traffic which uses the leaky bucket mechanism (token bucket). The performance evaluation studies based on modeling and simulation have shown that the proposed mechanism is able to ensure satisfactory levels of QoS to applications, meeting their average limited delay requirements, minimum sustainable throughput and limited packet drop rate.
