Fault Tolerant AP Placement with QoS Constraint in Wireless Local Area Networks

In this paper, the authors study the problem of enhancing the fault tolerance of IEEE 802.11 Wireless Local Area Networks in the design stage. Their goal is to place minimal number of APs (Access Points), such that the system can tolerate AP failures while guaranteeing QoS requirement. Given a set of clients (end-users) in a region, each client has a traffic demand for Internet access. Their concern is to find out minimal number of APs and their locations, so that both fault tolerance and QoS constraints can be satisfied. That is, when there is no AP failure, all clients' traffic demands should be met.
