A Wireless Sensor Network Testbed

Key design requirements for wireless sensor network (WSN) applications revolve around long battery life, low cost, small footprint and mesh-networking in supporting communication between large numbers of devices in an interoperable and multi-application environment. This paper presents a WSN testbed that aims to facilitate the developments and experiments of different routing algorithms. Numerous adaptive routing algorithms are implemented to offer self-healing capability for a wide range of WSN applications. Senor nodes in the network can connect together and to sensor gateways in star, mesh, and hybrid topologies. When any sensor node fails due to battery drain, physical destruction, hardware and/or software issues, etc, the network will dynamically route active connections around isolated network segments in order to minimize service interruption.
