Presentation title: Spatial-time coupling medium access control in underwater acoustic networks
Abstract: The propagation delay is non-negligible in underwater acoustic networks (UANs) since the propagation speed is five orders of magnitude smaller than the speed of light. In this case, the sending time and spatial distribution based propagation delay are strongly coupled to determine the arrival time of a received packet. In this talk, we will discuss the space-time coupling interference model for medium access control (MAC) in UANs. Based on the interference model, this talk will further discuss the design and performance analysis for MAC in centralised and mesh UANs. |
