A Generic Framework for Context-Aware Routing and its Implementation in Wireless Sensor Networks

Abstract:
As networks become more dynamic, the awareness of the network members’ current context is of growing importance. This can be said especially for communication networks, but also for other types of networks, e.g. logistic networks. Context-aware routing takes this context information into account when selecting routes in such networks. This paper introduces a novel generic framework for context-aware routing, including the message flow as well as the route decision method. The framework is not limited to a single application domain, but it is a generalized approach that can be adapted and specialized for various application domains. As an example, a wireless sensor network scenario is presented where this routing framework is applied.
