چکیده :

Publish-subscribe architecture is one of the dominating architectural styles in designing the Internet of things (IoT) monitoring applications. Establishment of brokerless publish-subscribe systems leads to exchanging a high number of control messages including advertisements, subscribes and updates messages which are used to inform the whole network about any changes in registered publishers and subscribers. Another problem is the in-efficiency in forwarding of publish messages in the resource-constrained IoT environment which results in network congestion, communication delay, and energy loss. The recent approaches in brokerless publish-subscribe systems for IoT domain introduced various methods including new communication protocols, maintaining routing tables for network nodes, and clustering the network. However, the efficiency in exchanging control messages does not receive much attention. In this paper, we propose an enhanced communication protocol to establish a brokerless publish-subscribe IoT system. The protocol is based on beaconing for packet dissemination. We applied a new structure that provides metadata in the packet header that facilitates the receivers regarding their next possible actions. The simulation results demonstrate that the proposed method reduces the network traffic by 28% on average and decreases the energy consumption of nodes up to 33% in comparison to the baseline method.
