Performance of Clustered Wireless Mesh Network with Default Gateway Association

Wireless Mesh Networks (WMNs) is gaining wide acceptance in wireless network users due to its unique features. It is also capturing major share of attention amongst researchers as it is in its evolutionary stage and its performance is still under observation. This paper discusses the performance of wireless mesh network where cluster of static nodes is associated with cluster head which serves as default Gateway for Internet access. The performance of static client scenario is evaluated on the basis of packet delivery ratio and end to end delay with varying transmission rate. A single cluster with one Gateway is compared with the case where the same number of nodes is forming around four clusters with each cluster head serving as a Gateway. Network Simulator NS-2 is used for evaluation. The results show that Multiple Gateway scenario provides better results as compared to Single Gateway
