A novel architecture for intelligent and adaptive wireless sensor network based alarming system

Wireless Sensor Networks (WSN) play very important role in information and communication Technology (ICT) and have attracted a lot of attention lately. The importance of these networks are increasing exponentially due to its usage in monitoring wide variety of applications. In this paper, we propose a novel architecture for intelligent alarm generation in a wireless sensor zone. We developed a decision support system for continuous monitoring the logged data for quality assurance across the zone, to raise alerts in terms of mail or message or alarm following any violation in the safety norm in an intelligent and adaptive manner. We implemented the system, by creating a Wireless Sensor Network Zone using Crossbow Imote2 sensor nodes. The standard Zigbee 802.15.4 protocol is used for communication. Our prototype system generates alerts in terms of SMS to predefined and authenticated mobile number(s) following detection of alarm in terms of fire, light, object movement and pH, Temperature, Salinity, Dissolved Oxygen of drinking water.
