Abstract

IEEE 802.11 WLAN is a most promising and demandable technology for communication. But it is affected by faults in the Access Points (APs), which degrade the network performance. So the network should tolerate the faults to preserve its performance and efficiency. In our approach, we have designed a fault tolerance technique to resist the faults in APs. This consists of three phases: Design of Minimum Cost Spanning Tree, creating Node Priority Table and establishing route to connect the nodes by Network Survivability Algorithm. By this method, we get the network coverage area, priorities of the nodes according to the degree and a route to connect the nodes after AP failure. We have considered it for both Single-Point Failure and Multi-Point Failure, which show better results in tolerating the faults by utilising maximum number of nodes and making it a cost-effective model.
