Throughput and delay analysis of IEEE802.11 string-topology multi-Hop networks <Abstract> The behavior of each node in Wireless Multi-hop Networks (WMNs) is so complex that comprehending network dynamics is challenging problem. As one of the solutions, the analyses of WMNs have attracted attention by many researches. This paper presents throughput and delay analysis of IEEE 802.11 string-topology multi-hop networks. For obtaining those with high accuracy, the operations of each node are expressed in detail. These expressions are associated as a network flow. Additionally, frame-existence probability, which is a new parameter for expressing the property in non-saturated condition, is defined. The validities of obtained expressions are confirmed by comparing with simulation results. |
