NashWifi: Coordinated management of heterogenous home 802.11 networks using bargaining

In this paper, we present an economically principled framework for coordinated configurations of heterogeneous wireless networks. Our approach, called NashWiFi, is based on the concept of Nash bargaining. We argue that NashWiFi can improve both the global performance of a large diverse 802.11 deployment, while also improving the local performance of individual applications in an equitable fashion. NashWiFi can accommodate applications with diverse needs ranging from file transfer to HD streaming. Extensive experiments using an implementation of NashWiFi support in the MadWifi driver and large scale simulations using Qualnet establish the salient features of our approach.
