This paper introduces an overview of throughput and delay analyses of IEEE 802.11 networks, mainly from authors' researches. In our opinion, the difficulty of wireless multi-hop network analysis comes from the network-dynamics multiplicity between uniformity and locality in spatiotemporal fields. From the background, the concept of “bottom-up analysis” was advocated, which is Network-layer modeling over MAC-layer one with respect to each node. Generalities of analytical expressions increase by applying the bottom-up analysis concept. Additionally, it is possible to express end-to-end delays by including the queuing theory in the bottom-up analysis concept. The validity of the obtained model is confirmed by comparisons with simulation results.
