Wireless mesh networks (WMNs) have been attracting significant attention due to their promising technology. The WMN technology is becoming a major avenue for the fourth generation of wireless mobility. In a Wireless Mesh Network, Mesh Routers (MRs) are interconnected by wireless links and constitute a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients (MCs). The wireless backbone is tightly integrated with the Internet by some selected nodes called as Gateways. The gateway has more capabilities than a simple MR and is more expensive. In this paper, the performance of WMN is improved by an energy aware gateway selection mechanism where the gateway is selected based on the threshold energy. Here the gateway to which the mesh routers are connected keeps on changing depending on the energy level of the current gateway. The performance of WMN using the single gateway is compared with the energy aware gateway selection scheme using ns2 simulator and the energy aware gateway selection scheme is found to exhibit more performance than the normal single gateway WMN architecture.

Abstract


Wireless mesh networks (WMNs) have been attracting significant attention due to their promising technology. The WMN technology is becoming a major avenue for the fourth generation of wireless mobility. In a Wireless Mesh Network, Mesh Routers (MRs) are interconnected by wireless links and constitute a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients (MCs). The wireless backbone is tightly integrated with the Internet by some selected nodes called as Gateways. The gateway has more capabilities than a simple MR and is more expensive. In this paper, the performance of WMN is improved by an energy aware gateway selection mechanism where the gateway is selected based on the threshold energy. Here the gateway to which the mesh routers are connected keeps on changing depending on the energy level of the current gateway. The performance of WMN using the single gateway is compared with the energy aware gateway selection scheme using ns2 simulator and the energy aware gateway selection scheme is found to exhibit more performance than the normal single gateway WMN architecture.
