A gateway-based approach for information retrieval from data-centric wireless sensor networks from IP hosts

It would be useful if an IP-based host could collect information from multiple remote data-centric networks using a predefined application programming interface (API). This research presents two APIs for gathering named data from remote WSNs - one API for wireless sensor nodes in the data-centric directed diffusion WSN and the other API for IP-based nodes residing on an IP network outside of the WSN. An associated WSN middleware layer used to effectively connect these two APIs through an application-layer gateway is also described. These three components work together in harmony to support gathering of sensed data from one or more remote WSNs through an application-layer gateway which connects different remote WSNs to an IP network.
