Abstract

In this paper, we propose to enhance a data-centric dissemination framework with geographic information and network-level caching in wireless sensor networks. The proposed framework enhances data-centric routing with three principal components: (1) publish/subscribe paradigm to coordinate sources and sinks; (2) geographic diffusion to mitigate unnecessary data forwarding; (3) network-level caching to process data or reduce redundancy in message delivery. We implemented the framework in ns-2 simulator, and conducted a simulation study to evaluate its performance in comparison with existing routing protocols. The simulation results indicate that the framework enhances message delivery ratio, reduces message delivery overhead, and saves energy consumption, regardless of wireless link errors.
