TAILIEUCHUNG - A new unicast routing algorithm for load balancing in multigateway wireless mesh networks

In this paper we propose a method named LBMGW for selecting appropriate gateways that aims load balancing in gateways and increasing network performance. LBMG is the measure for selecting a gateway which is a combination of measures such as negative percent hop, time, and internal load in each gateway. | International Journal of Computer Networks and Communications Security C , , NOVEMBER 2013, 251–256 Available online at: ISSN 2308-9830 N C S A New Unicast Routing Algorithm for Load Balancing in MultiGateway Wireless Mesh Networks Mohammad Karim Jafaryan1, Mohammad Ali Jabraeil Jamali2, Shahin Akbarpour3 1 Faculty of Engineering, Department of Computer ,East Azarbaijan Science and Research Branch, Islamic Azad university, Tabriz, Iran 2, 3 Department of Computer, Shabestar Branch, Islamic Azad University, Shabestar, Iran E-mail: , 2m_jamali@, 3sh_akbarpour@ ABSTRACT Gateways are a very important element of wireless mesh networks. They provide the connection between the whole network and the outside world, including the Internet. Since all of input and output traffic in the network go through gateways, these points are simply prone to congestion. Despite having multiple gateways in the network, in the absence of load balancing in the network, some of these gateways are still in danger of congestion that causes traffic aggregation in gateways, and hence, degrading of network throughput. In this paper we propose a method named LBMGW for selecting appropriate gateways that aims load balancing in gateways and increasing network performance. LBMG is the measure for selecting a gateway which is a combination of measures such as negative percent hop, time, and internal load in each gateway. Furthermore, some conditions have been considered to prevent control overhead inside the network. GloMoSim has been used for simulations. Then the results are compared with other available methods that show improvement in throughput of wireless mesh networks with the proposed method. Keywords: Wireless Mesh Network, Gateway load Balancing, Negative Percent Algorithms. 1 INTRODUCTION Recently, Wireless Mesh Networks [1, 2] (WMN) has received attention as a new generation of wireless networks for .
