1. INTRODUCTION
Development in Wireless Communication and networking has led to development of many applications like Bluetooth, Near Field Communications and Wireless Sensor Networks. A wireless sensor network is essentially a network of nodes which consist of a power supply, sensors which usually sense the ambient conditions and processors for storing and processing information collected and a transceiver unit which is used to transmit and receive information from other nodes. In addition it might have a GPS system which provides location based services. This Wireless Sensor network is divided into 3 main parts: Bottom nodes, cluster heads and network coordinators. The data collected by a node is transmitted to its cluster head, in turn, the data collected by the cluster head is sent to the network coordinator and data at the network coordinator can be sent to nearby clusters using a router and internet.

Wireless Sensor Networks are widely used in forest fire detection, wild life monitoring and mobile object tracking. In this paper we consider the application of wireless sensor networks in forest fire detection.
The nodes which consist of sensors like temperature sensor, smoke sensor and soil moisture sensor measure the ambient temperature and compare it with a set of threshold values. If the measured values are higher than the threshold values, the nodes will trigger an alert signal. The alert signal will consist of the…
