Force-Based Navigation in Wireless Sensornets
Certain scenario-oriented network tasks require a nontraditional approach to routing. This happens when routing should become aware of the node's state defined beyond the network layer (e.g., sensed value, current physical location, etc.). In this paper, the authors present an approach that helps software elements to navigate through the network based on the metaphors of fields and forces known from physics. The elements encapsulate logic to make a decision on the next move in the dynamic environment that is formed by overlapping, interacting fields and represent a physical value (e.g., fire) or a role (e.g., sink node). As a result, the force is induced on a node which pushes the element in a certain direction, towards or even away from the field source.
