Enhancing Security and Power Management in Wireless Sensor Networks

Heuristic techniques enable to select an information fusion of the selected sensor observation with the prior target location. The main objectives are to share the information about the target accurately, to adjust the power consuming in the sensors while transforming the information and to conserve the system resources by associating data tracks which is simpler in distributed environment of global consistency. Mutual information based sensor selection (MISS) algorithm is adopted to track the accurate information collaboratively. A novel approach to energy savings is devised as information-controlled transmission power (ICTP) where nodes with more information use higher transmission powers than those that are less informative to share their target state information with the neighboring nodes. One of the main challenges in this kind of application is security. Due to their key role in WSNs and also their fragility, localization systems can be the target of an attack that could compromise the entire functioning of a WSN and lead to incorrect military plans and decision making, among other problems. Here, we propose some techniques that can be used to prevent or impede the attacks in WSNs.
