A vehicle assisted offloading scheme for hotspot base stations on metropolitan streets
With field measurement data, it indicates that the data traffic of cellular networks is highly nonuniform along the city streets. The nonuniformity of the data traffic leads to overload in hot zones and inefficient use of wireless resources in light loaded zones. However, the intuitive solution is costly for such scenario of streets. To solve this problem, we propose a vehicle assisted offloading (VAO) scheme, which utilizes the vehicle queue stopping at the red light to offload data from the busy intersection cell to its adjacent cells that are largely idle. The performance of VAO is theoretically analyzed by considering both the road traffic conditions and the vehicle pedestrian communications. An architecture is also proposed to enable the offloading scheme. Simulations with practical parameters have confirmed our analysis and showed that the VAO is capable of achieving significant performance gain.
