Abstract and Objectives
Sensor Network Image
Our proposed sensor network system is automatially organized by lots of tiny nodes; each nodes composed of sensors, information processing units, and wireless communication functions on one silicon chip. This sensor network system accomplishes given missions. Each nodes has ability to modify and evolve its early functions so that it could adopt to its surroundings, thus this system will be optimized by itself to make it easy to solve the given missions. This function is one of the significant differences from other existing sensor network systems.
Specific applications are as follows:
Environment Sensing Network Systems:
In this sensor network system, nodes throwed to a field automatically organize their network system and send the required surrounding information of them to host. This system is targeted for environmental pollution monitor and applications to the home security.
Die-hard Network Systems:
If some nodes were broken, the nodes beside them work instead of them; the network system works normally. This network system is targeted for the information network systems whose communication isn’t disrupted by calamities.
