In this paper we propose a mechanism to improve survivability in IEEE 802.11 WLAN. Our approach consists of two main phases: Design and Fault Response. In Design phase, we deal with quantifying, placement and setting up of APs according to both area coverage and performance criteria. In Fault Response phase we consider the reconfiguration of active APs in order to deal with AP fault in the service area. We analyze changes in both power level and frequency channel assignment of the remaining APs, searching for the best configuration during the fault condition. We also propose area coverage and performance metrics to evaluate the effectiveness of the solution for the fault condition, according to the fault tolerance constrains de-fined in the Design phase. Finally, we present an implementation of the proposed techniques.
