Optimizing the Internet Gateway Deployment in a Wireless Mesh Network

Overview In a Wireless Mesh Network (WMN), Mesh Routers (MRs) are interconnected by wireless links and form a wireless backbone to provide ubiquitous high-speed Internet connectivity for mobile clients. The wireless backbone is tightly integrated with the Internet by nodes called as Internet GateWays (IGWs). This paper addresses the IGW deployment problem which is shown to be NP-hard. First it is formulate as a Linear Program (LP) issue, and then develop two heuristic algorithms for the purpose of cost-efficient IGW deployment. The paper further compares these algorithms with a leading approach by extensive simulations. This analysis shows the effectiveness of the proposed algorithms.
