Efficient Coordination in Internet-of-Things through Fast Many-to-Many Conveyance of Bulk-data

In advanced applications of Internet of Things (IoT), sharing of multimedia data is one of the common requirements which is not explicitly addressed in the existing works. The constraints of the low-power IoT-devices in their processing capability, memory, and energy, make efficient coordination based on the shared data quite challenging. In this paper, we study one such situation in the context of an IoT-assisted lightweight Intelligent-Transportation System (ITS). A many-tomany data-sharing strategy called ChainBus is proposed for fast sharing of bulk-data among the Road-Side Units (RSU) in ITS. Next, an efficient inter-RSU coordination mechanism is designed to dynamically infer the road-connectivity structure among the RSUs without the help of cloud. We show that our strategy can achieve its goal upto 54.3% faster compared to the solutions obtained by the existing best-known strategies.
