Abstract
Secure message forwarding and privacy in the large-scale heterogeneous Internet of Things (IoT)objects is a challenging task. User data confidentiality with an optimum number of forwarding nodes and minimum message replication rate are the significant factors in IoT networks. In this paper, we present Delay Aware Secure Hashing for Opportunistic (DASHOP) message forwarding in IoT network. Base stations as trusted authority coordinate with mobile social nodes and relay nodes. The divide-and-conquer rule establishes the secure, opportunistic and reliable paths in the network. The principle of optimality reduces the routing cost in IoT network. In the proposed DASHOP scheme, the message replication coefficient and message forwarding cost reduce the degree of channel access request, message transmission rate and jamming effects of adversary nodes in the network. Simulation results indicate that the proposed DASHOP scheme achieves high delivery rate with optimum trust levels and low message forwarding cost as compared to relay-based message forwarding and opportunistic forwarding schemes.
