Call capacity improvement techniques for VoIP over Wireless Mesh Networks
Wason Liwlompaisan, Anan Phonphoem · 2009
Due to the high overhead characteristics of wireless mesh network, the call capacity of VoIP is dramatically degraded. In the paper, the Aggregation Aware Routing with Path Separation (AAR-PS) protocol has been proposed. The protocol are designed by combining and engineering several techniques: packet aggregation, multi-path routing and event-triggered rerouting. The experiment results reveal that the protocol can accept more calls than existing protocols with acceptable packet delay according to the VoIP requirements.
