Wireless sensor networks consist of small nodes with sensing, computation and communication capabilities, often deployed in remote inaccessible areas to interact with the environment and forward the measured event to the base station, thus posing several possibilities of physical attacks. Hence security becomes an important issue in wireless sensor networks. For resource constrained environments like wireless sensor networks key pre-distribution is found to be better choice. Another significant information regarding network is the deployment knowledge which can be used to improve the performance of the key pre-distribution schemes. Deployment knowledge offers numerous advantages when used in resource constrained environments, achieving better storage, better resilience to node capture, minimizing the number of keys and reduce network overhead.
