SNMP Proxy for Wireless Sensor Network

In this paper the authors describe the implementation of a wireless sensor network of Micaz motes as a viable and effective solution for a health monitoring application that is connected to the Internet for global and remote monitoring. An architecture for this purpose has been developed. First, the network of wireless sensors gathers environmental and medical data and, using an enhanced graphical user interface (GUI) based on the CodeBlue software, then displays and stores data on the PC. The locally stored data are available for remote access via an SNMP-proxy connection. Finally a network management system installed on the remote server analyses the data collected. This approach provides a straightforward solution for an effective remote health monitoring application. The system has been tested using a series of experimental scenarios that have been established in the laboratory to (1) determine the reliability of the data collected from the mobile sensor network, and (2) determine the parameters for future expansion of the health monitoring network by introducing new sensors, alarm triggering algorithms, advanced security techniques, and location tracking capabilities.
