Abstract
In this paper, we consider interconnected IEEE 802.15.4 beacon enabled clusters with secure and reliable sensing. Each cluster has to contribute constant number of packets per second to the sink. Packets are protected with Message Authentication Code which requires secret key to be shared between each node and coordinator. We consider generic key exchange protocol with arbitrary complexity and periodic key update. Bridges between the clusters are implemented on cluster coordinators and participate in key exchange as regular nodes when they visit foreign cluster. We evaluate impact of complexity of key exchange protocol and level of event sensing reliability on the network lifetime.
