Fuzzy logic based propagation limiting method for message routing in wireless sensor networks

Abstract

Recent advances in micro sensors and wireless communications have enabled the wireless sensor networks. Also, a number of routing protocols have been proposed for the sensor networks. Especially, the directed diffusion is a data-centric and application-aware routing algorithm in which all communication is processed by the attribute-value pairs of the named data. In the directed diffusion, an interest message is propagated through all the nodes within the network. However, the propagation to all the nodes is inefficient in terms of energy consumption. To solve this problem, we propose a new data propagation method in which the data transmission area is limited according to a threshold value for reducing the energy consumption in the network. The fuzzy rule based system is exploited to determine the threshold value by considering the energy and density of all the deployed nodes. © Springer-Verlag Berlin Heidelberg 2006.
