WiPlatform, a sensing and event processing platform

This paper describes the WiPlatform, a scalable, sensing and event processing solution with applicability in building home automation systems, environmental monitoring systems, home care and other related applications. At the base of the system stays the WiSensors, a low power 802.11 Wi-Fi device powered by an RN-131C chip to which various sensors and actuators can be connected. Depending on the application requirements, a network of WiSensors with different sensing and action capabilities can be created. For each application a coordinator responsible for managing devices in the network and communicating with the application server, is required. The proposed solution presents a high level of flexibility, implementing a dynamic reconfiguration mechanism where the coordinator can be reprogrammed to act according the specific application and user needs.
