Channel Allocation and Routing For Throughput Optimization in Wireless Mesh Networks

S.Vijaya, R.Raja, V.Loganayagi

Various approaches have dedicated to maximizing the network throughput in a multichannel multi radio wireless mesh network. Recent solutions are based on either purely static or dynamic channel allocation approaches. One major problem facing wireless mesh network is the capacity reduction due wireless interference. The major challenge in multiradio multichannel wireless mesh network is the allocation of channels to interfaces of mesh routers so that network capacity can be maximized. Currently two approaches of channel allocation, that is, static approach and dynamic approach. In static channel allocation, each interface of every mesh router is assigned a channel permanently. In dynamic channel allocation, an interface is allowed to switch from one channel to another frequently. In proposed hybrid architecture which combines the advantages of both approaches that is one interface from each uses the dynamic channel allocation strategy, while other interfaces use the static channel allocation strategy. The links working on dynamic channels provide high throughput paths from end-users to the gateway while the links working on dynamic enhance the network’s adaptability to change the traffic. Therefore, hybrid architecture can achieve better adaptability compared to the purely static architecture without much increase of overhead compared to the purely dynamic architecture.
