|Title:||Throughput and Delay Analysis of Half-Duplex IEEE 802.11 Mesh Networks|
|Published:||June 06, 2011|
|Abstract:||Emerging technologies for mesh networks can provide users with last-mile service to an access point by forwarding data through wireless relays instead of through expensive wireline infrastructure. While an extensive amount of literature on mesh networks has been amassed in the last decade, existing papers model network flow solely as a function of the routing topology, neglecting contention at the MAC layer; as a result, the inbound flow to a relay station is independent of the transmission success rate from forwarding stations. This makes for inaccuracies in predicting throughput and delay, especially at network operation near or at full capacity. In our model, inbound traffic is dependent on the transmission success from forwarding stations. Other novel contributions are the incorporation of a half-duplex contention model we developed in previous work which captures both up-link and down-link flows and a generic framework to represent any routing topology (minimum-hop, minimum-airtime, etc.) in the model.|
