Mechanisms for Distributed Data Fusion and Reasoning in Wireless Sensor Networks

Decision making in decentralized and dynamic environments is challenging due to the continuous changes in the network topology and the absence of specific nodes that are responsible to take decisions. These challenges are increased in case of sensor networks deployments. In this paper, a novel approach is presented for realizing distributed data fusion and reasoning in wireless sensor networks. The approach is based on the storage and retrieval of data in stable overlay networks that abstract the physical network topology and the design of proper mechanisms for the semantic annotation of the available information in order to be used in the decision making process.
