Environmental Notification Support Using Passage Detecting Sensor Nodes

Daniel Reißner, Wolfram Hardt

Abstract

Interconnected sensor nodes can be used for a long term monitoring of widely spread ecosystems. Individual nodes can be unavailable during the runtime due to a lack of energy, disruption of communication channels, or physical damages of nodes. In this paper, a new approach to transfer messages from nodes to gateways (and optional to flood gate nodes) in such dynamically disturbed networks is presented. The focus is the routing in branched line-structures, e.g. flood barriers. The usage of gradient structures in each node allow tree routing, tree propagation, energy-efficient exploring broadcast, exploitation of line-structures, and collection of position information. Additionally, a generic preference evaluation and decision making concept allows energy or signal quality evaluation, routing decision, structure setup decision, position estimation, synchronization adaption, and randomization of security approaches. It can be extended by further rules.
