Self Organizing Wireless Sensor Network

Wireless sensor networks will enable low-cost connections between the physical world and telecommunications networks, with applications including security, industrial automation, remote exploration, and medical monitoring. After brie y discussing the underlying technology, we describe a protocol suite for self-organization of sensor networks, in which the number and topology of the sensor nodes are a priori unknown, and no timing has been made available. The scalable protocol very quickly establishes a TDMA and frequency assignment schedule, and then proceeds to establish energy-e cient routing. Simulation results will be demonstrated. We are in the process of porting the protocol to our network of 40 sensor nodes, and incorporating limited mobility features.
