Abstract-WSNs consist of a large number of small sensor nodes. These nodes are very cheap in terms of cost. In military operations, there is always a threat of being attacked by enemies. So, the use of these cheap sensor nodes will help to reduce the loss. In this paper, we analyze the existing literature of using WSNs for military applications. We will discuss the available scenarios of using sensor nodes in the military uses. Provided suitable sensors the system can detect identify and classify threads based on the count, number, type weather it is armored vehicles or men in foot, type and amount of weapons they carry, etc., can be detected in advance. This system provides reliable real time war picture and better situational awareness. This will further help to improve the troop readiness and decrease the reaction time. Added using the data collected tactical planning for deploying troops effectively can be done. In case of civil applications economic zones like oil fields, gold mines, can be protected from intruders and attackers. Industrial complex and production facility can be protected with minimized man power and improved efficiency. Basic criteria are which had to be taken into account while deploying wireless sensors for such applications has been discussed. Particularly locating the intruder with respect to the distance from the sensor node to the target in terms of latitude and longitudinal coordinates are discussed here.Index Terms-Radar signals, quantization error, friend identification, power management, perimeter defense.

Abstract-Due to uneven natural distribution of rain water it is very crucial for farmers to monitor and control the equal distribution of water to all crops in the whole farm or as per the requirement of the crop. There is no ideal irrigation method available which may be suitable for all weather conditions, soil structure and variety of crops cultures. Green house technology may be the best solution for this solution. All the parameters of greenhouse require a detailed analysis in order to choose the correct method. It is observed that farmers have to bear huge financial loss because of wrong prediction of weather and incorrect irrigation method to crops. In this contest with the evolution in wireless sensor technologies and miniaturized sensor devices, it is possible to uses them for automatic environment monitoring and controlling the parameters of greenhouse, for Precision Agriculture (PA) application. Now a days WSN is mainly focused on civilian applications such as environment monitoring, object tracking and bio-medical applications. They carry out collaborative activities due to limited resources, such as battery, processor and scarce memory. Nowadays, the applications of WSNs are several and diverse, and the applications in agriculture are still budding. One appealing WSN application is in environmental monitoring and greenhouses, where the plant conditions such as climate and soil does not depend on natural agents. To manage and monitor the environmental factors, sensors and actuators are critical. Under these circumstances, WSN should be used to make a distributed assessment, spreading sensors all over the greenhouse by means of distributed clustering. This paper reveals some grave issues when a wireless sensor network is exposed to real world environment to monitor and manage parameters like temperature, humidity, smoke, CO 2 , light and greenhouse gases and how distributed clustering mechanisms can be integrated within this monitoring process.

Abstract-Intelligent transportation systems (ITS) are advanced applications which, without embodying intelligence as such, aim to provide innovative services relating to different modes of transport and traffic management and enable various users to be better informed and make safer, more coordinated, and 'smarter' use of transport networks. Highway travel is the lifeblood of modern industrial nations. The larger roads are sorely over burdened: around the major cities, heavy usage slows most peak-hour travel on freeways to less than 60 kilometers per hour. In all excessive traffic causes more than five billion hours delay every year; it wastes countless gallons of fuel and needless multiplies exhaust emission. The main goal of this paper is to make the experience of driving less burdensome and accident less, especially on long trips. This can be achieved by making the highway itself part of the driving experience and integrating roadside technologies that would allow the overburdened highway system to be used more efficiently. The automobile will have automatic throttle, braking and steering control.
