Distributed Resources Management in Wireless LANs that Support Fault Tolerance

This chapter introduces a new radio resource management technique based on distributed dynamic channel assignment, and sharing load among Access Points (AP). Deploying wireless LANs (WLAN) at large scale is mainly affected by reliability, availability, fairness, scalability, and performance. These parameters will be a concern for most of managers who wanted to deploy WLANs. In order to address these concerns, a new radio resource management technique can be used in a new generation of wireless LAN equipment. This technique would include distributed dynamic channel assignment, and sharing load among Access Points (AP), which improves the network availability and reliability compared to centralized management techniques. In addition, it will help in increasing network capacities and improve its performance especially in large-scale WLANs. Analysis results using normal and binomial distribution have been included which indicate an improvement of performance resulted from network balancing when implementing distributed resources management at WLANs.
