... node in the network is linked as a chain. In each round, a node in the chaining structure is chosen as the chaining head. Both ends of the chain then start transmitting data to adjacent nodes in ... of the chaining head. In addition, each receiving node gathers the information. Finally, the chaining head transmits the information to the base station. In recent years, wireless s...
