A Call Admission Control Algorithm For Different QoS in Multihop Wireless Lans

For MAC (Media Access Control) protocol not providing QoS(Quality of Service) guarantees. With the increase of multimedia sevices in wireless networks(for example:voice, video, etc), when the networks get crowded, real-time applications will decrease its performance. We proposed a wireless network algorithm for 802.11e, witch supports fixed nodes and mobile nodes, and also swiches and new connections. Results imply that it can provide QoS guarantees under the existing vioce and video traffic, at the same time, it maintains a good performance in a most effective channel.
