Abstract: This paper addresses the problem of a scalable dynamic power control (SDPC) for wireless mesh networks (WMNs) based on IEEE 802.11 standards. An SDPC model that accounts for architectural complexities witnessed in multiple radios and hops communication system is designed. The key contribution is that the authors have first developed a general multiple transmission activity (MTA) model for each radio link. The authors then present a power selection policy that depends on average cross-layer network fluctuations as opposed to instantaneous fluctuations. Through simulations, the authors have observed that the SDPC modelled at the link layer, with the knowledge of imperfect and often delayed information, can significantly yield much power savings.
