Performance Maximization for Wireless Mesh Networks by incorporating Non Linear Cost Functions

Abstract: WMNs are multi-hop systems in which devices sustain each other in transmitting packets from beginning to end in the network. A mesh system offers multiple redundant interactions paths throughout the network. If one link fails for any reason, the network automatically routes messages through alternate paths. One of the principal issues in routing is to providing acceptable performance while scaling the wireless mesh network. It is appealing, however to look at what happens when routing nodes are extended in propagation environment and how that affects routing metric. In this paper, we examine the usage of different proactive, reactive and hybrid protocols in such a way so that we may be able to built a cost function which helps in selecting the optimum grouping of routing protocols for a particular urban wireless mesh network. The key metric is network throughput. A non linear cost function equation has been proposed analogous to routing metric taken. Bit rate is in use as constant (CBR).
