Congestion Propagation in Multihop Wireless Networks

Multihop Wireless Networks (MWNs) are expected to expand the area of wireless access networks, which consist of multiple access points in the area of a wireless LAN and connect these access points with wireless links. However, the MWNs still have many issues to provide good quality of service. For example, it is not clear about traffic characteristics over the MWNs. In this paper, therefore, we investigate the characteristics of MWNs based on the congestion propagation between wireless routers reported in wired networks. Furthermore, we show the impact of the congestion propagation on the network performance in various network parameters by means of simulations.
