Capacity has been an important issue for many wireless backhaul networks. Both the multihop nature and the large per packet channel access overhead can lead to its low channel efficiency. The problem may get even worse when there are many applications transmitting packets with small data payloads, e.g., Voice over Internet protocol (VoIP). Previously, the use of multiple parallel channels and employing...
A packet scheduling scheme in the downlink channel for IEEE 802.16 is proposed.The scheme can be implemented in the base station and is compatible to the MAC protocol of IEEE 802.16. In order incorporate the properties of location-dependent and burst error of wireless channels, we design a novel packet scheduling algorithm named the credit-based algorithm (CBA) to guarantee QoS of both real-time and...
