Research in Wireless Sensor Networks (WSN) is widespread and pervasive in many disciplines because of the potential to embed tiny, inexpensive, low-power sensors in many environments to provide a wide range of surveillance and monitoring applications. A key advantage of WSN is that the network can be deployed on the fly and can operate unattended, without the need for any pre-existing infrastructure and with little maintenance. Typically, sensor nodes are deployed randomly (e.g., via aerial deployment), and are expected to self-organize to form a multi-hop network. A sensor node is capable of sensing some physical phenomenon (e.g., detect tank vibrations or sniper gun noise), processing the sensed data and communicating the observed measurements to fusion nodes, also called micro-servers. The sensor nodes may also perform data aggregation/compression to reduce the communication overhead in the network. The prime idea of FCS concept is to support the soldier with real time situational awareness and joint operability among forces to complete a mission successfully with low mortality rate. This system allows the soldier to see first, understand first and act decisively. Basic work done behind the screen is fusing data collected from different reconnaissance vehicle, unattended ground sensors, unmanned aerial vehicles and live assets. System of system common operating environment supports the system. SOSCOE provides reusable software architecture for platform and battle command application via low bandwidth Adhoc network. It uses TINEX workflow engine which minimizes traffic and allows different software to execute flexibly. Since, most of the system operates in remote environment with battery support, power consumption is a serious issue. System with many nodal points has to be encrypted strictly to prevent the network from attacks (simply hacking).
