Wireless sensor network (WSN) deployments often require a back-end network and a data visualizer. Motivated by this, the authors have designed an integrated framework for WSNs with a custom hardware sensor mote, and a back-end network visualizer and alert manager.

The customized hardware sensor mote, IITH-Mote, is designed as part of the overall framework. The IITH-Mote includes an IEEE 802.15.4 radio and an 8 MHz Atmega microcontroller, and runs on the TinyOS sensor network operating system. With this sensor mote, a 13-node multihop data collection sensor network is deployed and designed. A Java-based network visualizer is deployed on the back-end to monitor the sensor network. A sensor network surveillance-based application is designed to detect when the sound signal level is above a threshold.

There are some assumptions mentioned in the paper that are not correct. For example, the authors note that “most ... existing visualization tools support only a single type of sensor network related to the TinyOS.” In addition, there are some notions of multihop sensor network operations described that are not very standard. But overall, the literature on available sensor network visualization tools is well discussed. This work may be somewhat useful for people interested in sensor network visualization.
