Dynamic Load Balancing Algorithm Based on Users Immigration in Wireless LANs

Abstract

Abstract-This paper discusses a throughput improvement based dynamic load balancing approach for wireless LANs. The proposed scheme checks each AP's load state and balances overloaded APs by immigrating some wireless stations towards under loaded one, periodically. Each wireless stations has different throughput with different APs, respectively. Immigration can be accomplished with considering throughput value between wireless station and under loaded APs. The system overload is uniformly distributed among under loaded cells that wireless stations from overloaded cell moves to most under loaded cell first. The load balancing algorithm mostly considers throughput improvement in imbalance state of the system. Simulation results show that proposed load balancing yields significant performance gains in terms of system throughput and data loss due to overloading.Index Terms-Dynamic load balancing algorithm, immigration, wireless local area networks.

Multi-path Routing for Mission Critical Applications in Software-Defined Networks

“…The network thus must be reliable and resilient in order to support such applications where by in case of a network failure, peoples lives and companies can be at risk. Load balancing has been an existing problem in providing reliable network by assuring the system is not overloaded and also by high resource utilisation [1], [2]. With the emergence of the Software Defined Networking (SDN) paradigm which has been triumphed as a reliable and resilient solution for future Internet, mission-critical networks can be improved in reliability, resilience and security by leveraging SDNs features.…”
