Load Balancing on Multi Channels Through Gateways
Sirajul Huque, Priyanka Sarma, A Thirupathaiah · 2012
We propose an adaptive online load-balancing protocol for MultiGateway Wireless Mesh Networks (WMNs) which, based on the current network conditions, balances load between gateways. Our protocol (GWLB) achieves two goals: (i) alleviating congestion in affected domains and (ii) balancing load to improve flow fairness across domains. As a result of applying GWLB the throughput and fairness of flows improves. So, the proposed scheme effectively takes into account the elastic nature of TCP traffic, and intraflow and inter-flow interference when switching flows between domains. .The existing scheme contains maximizing network throughput while providing fairness is one of the key challenges in wireless LANs (WLANs). This is typically achieved when the load of access points (APs) is balanced and imbalance of load, several load balancing schemes have been proposed. These schemes commonly require proprietary software or hardware at the user side for controlling the user-AP association by controlling the size of WLAN cells. The existing scheme does not support to the users neither the IEEE 802.11 standards. It only requires the ability of dynamically changing the transmission power of the AP beacon messages. But we failed to set polynomial time algorithms which minimize the load of the most congested AP. We also consider the problem of network-wide min-max load balancing. Unable to show Simulation results the performance of the proposed method is comparable with or superior to the best existing association-based method.
