Self-configuration for surveillance sensor network

This paper describes an autonomous monitoring system to supervise environmental parameters such as temperature, humidity, poisonous gases or smoke concentration, etc. This system is designed as a set of sensor nodes connected via a wireless network. The feature of this system is its ability to autonomously configure the network structure and synchronize data between nodes. This allows the network to be fault-tolerant. Each sensor node consists of three layers. The bottom layer includes a 5 to 12 volts battery and a stabilizer. The middle level consists of an 8-bit microcontroller, LCD (Liquid Crystal Display), SD (Secure Digital) card reader, and a set of sensors. The top level includes RF (Radio Frequency) communication module and GPS (Global Positioning System) module. Each sensor node is able to work as a standalone unit and as a part of a sensor network. The experimental works were performed for ensuring worth using in real time.
