A context-aware architecture for wireless sensor networks

Abstract

Unlike those traditional layered architectures, a non-layered protocol architecture for WSNs is proposed in this paper. The goals are greater flexibility and reliability with less network resource consumption. Based on the concept of micro-modularization, the context-aware architecture allows functions to be automatically composed within each sensor node according to the context information. An experimental simulation shows that, our proposal efficiently utilizes network resources, meanwhile provides good network performances. © Springer-Verlag Berlin Heidelberg 2012.
