TARA: weighted majority cooperative game theory-based task assignment and resource allocation in 5G heterogeneous fog network for IoT

A weighted majority cooperative game (WMCG) theory-based heterogeneous fog architecture with fog-to-fog (F2F) communication is proposed in this article to reduce the delay and power consumption of the network. The fog devices are participated as players in the game, and they are operated cooperatively to perform a task. If one fog device is unable to complete the task, only a part of task is completed by it and the remaining task is completed by neighbour fog devices. Among the neighbour fog devices, the high majority fog device is selected using WMCG. The proposed TARA has generated ∼ 7–24, 9–28 and 11–30% less delay and ∼ 9–28, 11–31, and 12–32% less power consumption for transmitting 1 Kb, 5 Kb, and 10 Kb of data, respectively, than other networks. Results show that the proposed TARA is a delay and power efficient network.
