Internet of Things is a crucial research empire in the current era which enables a wide diversity of applications. One of the emerging classes of technology in recent age dominate the universe of IoT is the concept of the Internet of Drones Thing (IoDT). The following work fundamentally emphasizes the key concepts of the Internet of Drones architecture in the context of the Edge computing perspective. A state of the art “EdgeDrone” concept has been engineered where the standard message transfer strategy of IoT and the opportunistic Ad-Hoc network have been amalgamated. Parameters like message transfer latency, overhead ratio, message delivery chances under several QoS values and resource usage, energy performance for the protocol have been analyzed. A hardware testbed has been implemented with the JavaScript platform along with the simulation which has been executed after tuning the performance of the protocols. The result shows 30% improvement in average packet delivery for enhanced MQTT-SN and about 17% improvement for enhanced MQTT in comparing to standard strategy. The study also reveals the minimum value of the message delivery latency of 15.5 msec for enhanced MQTT-SN in QoS-1. In memory usage point of view, the result shows that the MQTT broker takes a maximum of 5.6 MB of memory during enhanced MQTT-SN takes to publish–subscribe operation which is significantly less. Another two major parameters which report the maximum message transfer bandwidth of 620 msg/sec for enhanced MQTT-SN at QoS 1 and about 1800 msg/sec for QoS 0 as well as the enhanced MQTT-SN within 802.15.4 interface ensures minimum energy consumption amongst all other strategies [Display omitted]
