Abstract:

Wireless ad-hoc networks are highly dynamic networks for which routing is a challenging task. Existing routing protocols whether reactive, proactive or hybrid showed limitations in various situations. To optimize the behavior of the routing nodes, the academic community is recommending the reliance on an autonomic approach that would guarantee self-adaptation, self-configuration, self - management, and self - protection mechanisms of all the network nodes. In this paper we propose an autonomic architecture geared towards improving the routing service within wireless ad-hoc networks. This architecture provides a formal framework where each node has a routing agent whose role is to monitor routing activities within the network, which are used to tune the routing decisions of the node, in harmony with other nodes. Simulation results with an autonomic implementation of AODV show remarkable performance improvement with respect to efficiency (Packet Delivery Ratio improved on average by 20.65%), overhead (average reduction of 16.7%), quality of paths (average path delay reduced by 37.14% in low mobility and 19.68% in high mobility), and reliability (an average of 789.35 for 900sec of simulation)
