Sensor network is a system of nodes where each node is equipped with a battery which is used to supply power, a certain amount of computation, communication, a device for sensing and with some storage media. The reliability of wireless sensor networks is affected by faults that may occur due to various reasons such as malfunctioning hardware, environmental hazards e.g. fire or flood or dislocation of the sensor node. In this paper we have proposed a method of introduction a level of fault tolerance in to wireless object tracking sensor networks by monitoring the status of each wireless sensor node. Sensor networks are such networks which have to operate unattended for long periods. There for fault tolerance mechanisms are needed to protect these networks from various faults such as node failure due to loss of power, link failure, or even the failure of gateway nodes.

[...] In this paper we have tried to introduce the concept of fault tolerance in Object Tracking Sensor Network (OTSN) in the battle field to continuously monitor the movements WORKING OF SENSOR NETWORK Sensor Networks is an interdisciplinary research area and draws contributions from signal processing, networking and protocols, databases and information management, distributed algorithms and embedded systems and architecture areas. Various terminologies are used for sensor networks as: o Sensor: A transducer that converts a physical phenomenon such as heat, light, sound, or motion into electric or other signals that may be further manipulated by other apparatus.

[...] Moreover, self-healing should achieve-containment otherwise a fault in one region of the network may contaminate and hindering the availability of the tracking services. For the purpose of fault tolerance in object tracking sensor network we propose a two tier structure in which node will be deployed in a pair. Initially one node starts working and sends information to the base station of the object tracked by the node. When this node cause any fault and stop functioning properly then another node will take control over the previous one and establish in the network. [...]
