Agent based Connectivity Detection and Routing in Mobile Ad-hoc Networks

The proposed scheme uses an agent-based model to address the aspect of connectivity detection and routing in mobile ad-hoc wireless network environment. Three kinds of agents are used in the model: manager agent (MA), monitoring agent (MOA), and discovery-routing agents (DRA). MOAs of a node in a network are employed to monitor resources (such as transmit power, battery life, bandwidth, reliability, one-hop delay), whereas DRAs discover the links between the mobile nodes, perform routing information fusion and build pre-computed paths so that mobile users can communicate with each other based on the requirements (power/bandwidth/reliability/bandwidth-delay aware) of the network users. MA manages the activities of the discovery and routing agency. The model ensures network connectivity even under the conditions of uncontrolled mobility of nodes. Model has been simulated to test its operation effectiveness. It is observed that agent based approach supports component based software engineering features and facilitates flexible and adaptable discovery and routing information fusion services
