Mobile Ad-hoc Networks (MANETs) are fully distributed networks that consist of fully-connected collaborative nodes. Each node in the network can act as a relay, if required, in order to route information from source to destination nodes. Traditional routing approaches that are being further investigated for standardisation at the Internet Engineering Task Force (IETF) are flat reactive and proactive routing protocols such as Ad-hoc On-demand Distance Vector (AODV) routing and Optimised Link State Routing (OLSR) respectively. However, in literature, various more elaborate approaches have been presented based on hybrid routing solutions which include nature inspired routing algorithms, cluster based routing as well as proactive-reactive zonal based routing. A further avenue towards optimising the flat routing approaches in MANETs is to adopt a converged hybrid routing approach where the nodes in the network use cognitive algorithms to detect the state of the network and adapt the routing approach to fit these conditions. Furthermore, in order to tackle the issue of deploying ad-hoc networks, a more realistic cognitive and adaptive framework is required. In this paper, we describe our work towards the development of such a converged routing approach and a suitable Cognitive and Adaptive Module (CAM), which is patent pending, for MANET deployments.
