Smart Approach for Discovering Gateways in Mobile Ad Hoc Network

摘要

Providing Internet access for nodes in wireless mesh networks or Mobile Ad hoc Network (MANET) is one of the most critical and challenging processes. Multiple gateways (GWs) are deployed to enhance the capability of MANET. Many of the existing routing protocols, either using the traditional routing approaches or using the tree-based network's approach, are employed and enhanced to work with MANET. However, as MANET is dynamic and temporary networks, using current methods fail to discover new or failure GWs and are required more overhead on the network. To handle this gap, the work presented in this paper utilizes swarm intelligence techniques to build a routing approach dedicated to MENET that works well to discover new GWs, checks, and maintains existing paths to the GWs. Furthermore, it can discover new paths to existing GWs, detect any link failure in any path, and try to fix it. Many experiments were conducted to validate the suggested routing approach, and the results reveal the applicability of the suggested model.
