Energy & Time Performance Metrics in Wireless Sensor Network

Wireless sensor networks (WSNs) represent a new computing class consisting of large numbers of resource-constrained nodes which are often embedded in their operating environments, distributed over wide geographic areas, or located in remote and largely inaccessible regions also faces the security problem. Lots of security solutions are available for wired networks which can be used for wireless networks, but because of low form factor properties of wireless nodes which are also mobile, it is infeasible to deploy the complex security solutions for wireless networks. In WSNs, challenges such as wireless nature, low battery power and mobility are prime reasons why we are not able to deploy complex security solutions. Hence it is important to study, design and analyze security solutions for this kind of networks. Therefore, the concept of Cryptography Assistant is introduced, which is assumed to be highly powered device compared to sensor node. The crypto assistant node is capable of implementing high end cryptography algorithm. This work mainly focused on energy and time tradeoff of encryption algorithms and files communication
