Understanding and Tackling the Root Causes of Instability in Wireless Mesh Networks: (Extended Version)

The authors addressed the problem of network stability in CSMA-based linear wireless mesh network and provide three main contributions. First, they identified two key factors impacting the stability: the network size and an artifact that they called stealing effect. Second, they proved analytically and showed experimentally that 3-hop networks are stable when they account for the stealing effect, but 4-hop networks (and presumably larger topologies) are not. Third, they proposed and designed EZ-flow, a new flow control mechanism for IEEE 802.11 WMNs.
