An Integral Approach to Programming Sensor Networks

In this paper we present a complete approach to programming sensor networks. The main contribution concerns the separation of three abstraction levels, viz., application level, network level and node level, leaving more room for standardization than with current practices. In addition we propose to program the network from an overall perspective rather than programming individual nodes. The proposed model is event- based, corresponding closely to the nature of wireless sensors and admits content-based addressing of nodes and groups of nodes. The paper describes how the three abstraction levels come together and gives examples of the approach at all three levels.
