【 摘 要 】

Secure communication in a Wireless Sensor Network (WSN) can be achieved through efficient key managementtechniques. Achieving security is not so simple due to the limited capability of radio module in wireless sensornetwork device. The probabilistic model provides a flexible and efficient solution when comparing various keydistribution schemes developed so far. Here, we propose an Optimal Resource Key Management Protocol(ORKMP) considering the limited capabilities of WSN for a Clustered Heterogeneous Wireless Sensor Network(CHWSN) which follows a hierarchy. Better performance and scalable security solutions can be achieved byheterogeneous sensor nodes. The sensor nodes are deployed in groups, each controlled by a cluster head, whichleads to less communication overhead. The keys distributed to nodes are based on the probabilistic model whichcombines the deployment knowledge with the sensor node’s attributes of signal range and state. This hybrid effectreduces the memory requirement, by sustaining high connectivity and resilience. On the whole, the proposed keymanagement protocol provides an efficient security solution with optimum resource requirement.
