Flashback: decoupled lightweight wireless control
Unlike their cellular counterparts, Wi-Fi networks do not have the luxury of a dedicated control plane that is decoupled from the data plane. Consequently, Wi-Fi struggles to provide many of the capabilities that are taken for granted in cellular networks, including efficient and fair resource allocation, QoS and handoffs. The reason for the lack of a control plane with designated spectrum is that it would impose significant overhead. This is at odds with Wi-Fi’s goal of providing a simple, plug-and-play network. In this paper we present Flashback, a novel technique that provides a decoupled low overhead control plane for wireless networks that retains the simplicity of Wi-Fi’s distributed asynchronous operation. Flashback allows nodes to reliably send short control messages concurrently with data transmissions, while ensuring that data packets are decoded correctly without harming throughput. We utilize Flashback’s novel messaging capability to design, implement and experimen...
