Emerging mobile device applications, like those supporting augmented reality, require high data rates, but the rapidly growing number of devices connecting to the internet complicates the network and increases backhaul infrastructure cost. Small cells (devices that connect to a network via DSL or cable) offer better reception and reduced transmit power for prolonging battery life. However, interference between cells constrains network performance. Scarcity of the radio frequency spectrum, lack of coordination between small cells and networks, and complex requirements at the mobile device require the small cells to share network resources. Therefore, there is a need to create a novel wireless network architecture supporting small cells that mitigates interference.
Researchers at ASU have developed a novel wireless network architecture for small cells using software defined networking (SDN). The SDN-based backhaul network, Smart Gateway (Sm-GW), leverages available network resources to throttle data transfer, effectively reducing bottlenecking and delivering seamless internet access to a higher number of devices. SDN configures the backhaul and equally distributes resources to provide a uniform rate of data to the small cells without installing costly infrastructure. In conclusion, the network architecture increases user capacity through optimal resource distribution, resulting in enhanced coverage, reliable connectivity, and reduced operational and capital costs.
