Enhanced Intra-Cluster Network Routing Scheme for Efficient Wireless Mesh Network B Divya Reddy + and J Faritha Banu RMK Engineering College, Kavaraipettai, Chennai, India Abstract. This paper proposes a load control routing scheme for intra cluster routing in wireless mesh networks. Unlike other existing schemes proposed for load balancing for wireless mesh networks, this routing scheme implements in a different manner for both Inter-cluster and Intra-cluster routing based on Load Aware Routing by forming a Virtual Network and use the free nodes inside the cluster to route the data instead of cluster head. This method reduces the load on the respective cluster head, which is used for efficient Inter-cluster routing. This improves performance of the network increases. We prove through simulations that load on the particular cluster head is reduced by taking number of flows into account. Keywords: wireless mesh networks, load-balancing, inter-clustering, intra-clustering. 1. Introduction A Wireless mesh network (WMN) is a communication network made up of radio nodes, organized in a mesh topology. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. In this network nodes act as routers to transmit data from nearby nodes to distances. One of the main concerns for wireless mesh networks is the reduction of the overall network capacity due to the interference between adjacent nodes. In a wireless mesh network traffic load tends to be unevenly distributed over the network. In this situation the utility of the network had been decreased. In the WMN, a great portion of users intends to communicate with outside networks via the wired gateways. In such environment, the wireless links around the gateways are likely to be a bottleneck of the network. If the routing algorithm does not take the account of the traffic load, some gateways may be overloaded while the others may not. This load imbalance can be resolved by introducing a load-aware routing scheme that adopts the routing metric with load factor. When the load-aware routing algorithm is designed to maximize the system capacity, the major benefit of the load-aware routing is the enhancement of the overall system capacity. Although there have been some works on load-aware routing for mobile ad-hoc networks and WMN’s, they simply include some load factors in the routing metric without consideration of the system-wide performance. In this paper , we proposes a load control routing scheme for intra cluster routing in wireless mesh networks, which maximizes the overall network performance. We can implement this routing scheme by forming virtual network. Using this method, we can not only reduce the load on the cluster head but also reduces the end-end delay in the network. The paper is organized as follows: Section 2 gives the related works, Section 3 presents the existing system and its drawbacks, and Section 4 presents the proposed system with the support of results presented in section 5. Section 6 concludes the paper. 2. Related Work + Corresponding author. Tel.: + 91 96 76 89 3066.
