ABSTRACT The broadcast data dissemination is an important transmission mode of wireless sensor networks (WSNs) in Internet-of-Things (IoT) systems. Seeking the optimal forwarding path of the broadcast data is a non-deterministic polynomial problem, and therefore, we tried to use the theory of opportunistic routing for reducing redundant rebroadcasts and enhancing the trustworthiness of transmission. However, minimum research is available focusing on the opportunistic broadcast in planar structure network which is point-to-multipoint transmission model. This paper explores the performance of broadcast data dissemination by using opportunistic routing for point-to-multipoint in theory. A new protocol called receiver negotiation opportunity broadcast (RNOB) protocol is proposed, including the distributed cooperation scheme and the priority scheduling algorithm. Simulation results showed that the performance of RNOB is better than traditional protocols, which shall improve the trustworthiness and efficiency of data transmission for WSNs in IoT systems.
