Sensor networks are very important for military applications and in particular in battlefields. Sensors can collect very detailed information about enemy, its movements, weapons, and so forth. However, it is important that the information gathered by sensors arrives quickly to the destination, which could be moving objects such as tanks, solders, flying devices, and so on.The security of information in such as dynamic environment is paramount. Therefore, we have developed a new security scheme based on key distribution among stationary sensor networks and mobile data collection nodes. Our scheme is based on key predistribution using separate key pool. The scheme allows the mobile nodes to interact with the stationary nodes of different networks. In our solution, a separate key pool is used to connect the mobile nodes to the stationary nodes. We have performed extensive analysis and simulations to validate the scheme and compare its performance.
