IETF MANET Working Group Internet-Draft Intended status: Informational

This document describes a generic Cognitive Adaptive Module (CAM) that can be utilized in conjunction with Mobile Ad hoc Network (MANET) routing protocols. The main concept behind CAM is the fact that the provisioning of multimedia communications traditionally requires routing Quality of Service (QoS) guarantees [9]. Such a task is NP Complete in MANETs when QoS optimization is subject to more than one parameter [9]. Hence, the provisioning of soft QoS guarantees for effective and efficient routing in dynamic environments, as specified in [1], is the best alternative. However, the latter cannot be optimally achieved by using a single metric based path selection process or routing approach due to variations in both upper layer service QoS requirements and situational constraints. CAM provides interfaces to routing components such that protocols can be segmented into these components and can be easily made configurable and adaptive. For instance, the route selection process can be done in an adaptive manner to satisfy the requirements for effective and efficient routing. This is achieved by providing interfaces from the CAM core to various user defined components (e.g. Repositories Component) such that all components and component parts (e.g. DYMO reactive routing logic) can intercommunicate.
