End-to-end throughput analysis for IEEE 802.11 string-topology multi-hop networks with two-way flows <Abstract> String-topology network is often selected as an analysis object because it is one of the fundamental and simple multi-hop network topologies. This paper presents the end-to-end throughput analysis for IEEE 802.11 string-topology multi-hop networks. The analytical expressions obtained in this paper give end-to-end throughputs with two-way flows for both asymmetric and symmetric offered loads. The analytical predictions agree with simulation results well, which show validity of the obtained analytical expressions. |
