With expanding applications of the opportunistic Internet of Things (IoT), there has been ever-increasing enthusiasm in integrating blockchain with the IoT for enhancing privacy and security. However, due to high resource consumption by the blockchain, its implementation becomes challenging task for IoT networks. A traditional opportunistic IoT network sends multiple copies of messages for communicating information from source to destination, which gives rise to two risky situations: communication overhead and network security. Therefore, this paper proposes a probabilistic-based blockchain algorithm for opportunistic IoT network.
The algorithm presents a secure routing protocol based on the delivery predictability of messages by integrating blockchain to ensure security and privacy. The simulation results shows that our proposed protocol outperforms some traditional routing schemes like epidemic routing and PRoPHET (Probabilistic Routing Protocol using History of Encounters and Transitivity) routing with more secure transmission.
