A Survey on Consensus Algorithms for Distributed Wireless Networks

A distributed wireless communication system consists of multiple nodes. Due to the diversified resources and environmental conditions for each node, a consensus-based algorithm can be used to solve the conflicts in the wireless communication system so that each node can reach a consensus based on a consistent algorithm and a consistent result. In particular, the channel quality, signal strength, energy consumption, protocol delay, security, and reliability can be improved. Consensus algorithms can also be applied for channel decision-making, authentication problems, message routing problems, and fault tolerance problems. Consensus algorithms are becoming essential for safe and more reliable wireless communication systems. Focusing on consensus algorithms from the perspective of wireless communication applications, the survey compares current trends and emerging research opportunities in consensus algorithms. Finally, we provide future research directions for consensus algorithms for distributed wireless networks.
