Autonomous sensors nodes to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a receiver (destination) [1] [7].

Military Applications: The origin of wireless sensor networks is from defence research, therefore there are vast applications in military where sensor nodes can be deployed in warfield surveillance to detect, locate and monitor enemy activities.

In these modern times when communication has become a fundamental tool for progress and advancement on many terms, it is already considered an imperative for many companies and businesses to improve their communication and information technology. The advent of new technologies and the introduction of newer softwares and tools necessary for survival in the tough and competitive market make it possible for many businesses and companies to reach their employees, other partner markets or businesses and even their customers while on the move. This is the gift of wireless devices and applications technology.

With the recent technological advancements of smaller sensor devices enabling ubiquitous sensing capabilities and driven by the adoption of global standard technologies, Wireless Sensor networks (WSN) are evolving as one of the most significant technologies of 21st century (Ruiz-Garcia, Lunadei, Barreiro, & Robla, 2009). Though wired networks provide more stable and reliable communication, sensor networks with dense wireless networks of small, low cost sensors collecting and disseminating environment data has facilitated monitoring and controlling of physical environments from remote locations with better accuracy. Moreover, with the unique characteristics of flexibility, energy efficiency, distributed intelligence, low cost and most importantly with very good monitoring capabilities Wireless sensor networks serve wide range of applications in various fields such as remote environmental monitoring, home security, industry applications, military purposes such as target tracking along with preparing a ubiquitous computing environment (Ruiz-Garcia et al., 2009).

A Wireless Sensor Network or WSN is supposed to be made up of a large number of sensors and at least one base station. The sensors are autonomous small devices with several constraints like the battery power, computation capacity, communication range and memory. They also are supplied with transceivers to gather information from its environment and pass it on up to a certain base station, where the measured parameters can be stored and available for the end user.

A wireless sensor network (WSN) is a computer network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.[1] The development of wireless sensor networks was originally motivated by military applications such as battlefield surveillance. However, wireless sensor networks are now used in many civilian application areas, including environment and habitat monitoring, healthcare applications, home automation, and traffic control.[1][2]

The grouping of various sensor nodes makeup a huge Wireless Sensor Network (WSN). These wireless sensor networks are employed in environments where human reach is difficult. The sensor nodes are small, inexpensive, battery powered devices which are capable of local processing and wireless communication. These sensors cooperatively work with each other to sense some physical circumstances and then the information is gathered and processed to get pertinent results. The information that is gathered is sent to the main location.

Wireless Sensor Networks (WSN) consists of large number of sensor nodes distributed across a geographical area in highly dense manner. These nodes are of low cost and use less energy to perform various functions. These sensors have the ability to communicate with each other and route the data to next node or back to the Base Station (BS). Sensor nodes in a sensor network communicate with other nodes and collect the information.

Sensors are small, low-cost and low-power communication devices which detects or measures a physical property and records, indicates, or otherwise responds to it. Basically, a single sensor node comprises a sensing part, power source, transceiver and processor. The sensing part enables them to collect information of a particular interest. Moreover, it determines their application. The type of power source a sensor node employs has a significant effect on the size, cost and longevity of the node. The integrated transceiver provides sensor nodes the capability for wireless communication between each other or as a network of devices. Hence, the term Wireless Sensor Networks.

A mobile wireless sensor network, shortly WMSN, can be defined as a wireless network of a sensor nodes that are mobile. Motivation behind a mobile wireless sensor network is to capture real world data and convert them so it can be transferred, processed, stored and later studied or analyzed (Guo, 2014). The MWSN is usually a combination of two or more technologies such as mobility, wireless connectivity and the ability to gather local information. The mobile wireless sensor network is usually deployment of a large number of small, inexpensive, self-powered nodes and receiving station (Kumbhare, Rangaree, & Asutkar, 2016). These MWSN can be effectively used for civil and military purposes.

The wireless sensor networks mainly comprise stationary and mobile sensors that are deployed randomly inside the network and they collect data from the surroundings via wireless communication links [7, 8].

Wireless sensor networks can play a key role in military command.This can be in form of control, easier communication, better surveillance etc. The ability of sensor network to rapidly deploy, privately organize and fault tolerance characteristic make them an admirable technique for sensing in application for military. Sensor networks can be applied in several aspects in the military including: observing friendly forces, equipment and ammunition; surveillance of the battlefield; organization of opposing forces and the terrain; also targeting; assessment of battle damage; and nuclear, and detection of biological and chemical attack
