Due to the rapid growth in wireless local area networks (WLANs), it is important to characterize the fine structure of user association patterns. In this paper we focus on understanding the structure in user’s daily access point (AP) association patterns in WLANs in the long run. We propose new methodologies to systematically analyze the WLAN user traces and utilize USC WLAN trace as a case stu...

Target-to-user (T2U) association is a prerequisite to fully exploit the potential of sensing function in communication-centric integrated and communication (ISAC) systems, e.g., for beam blockage management. This letter proposes purposely mount RIS on roof vehicular user equipment (VUE), which can serve as an intentional back-reflector towards base station. By controlling reflection pattern ove...

The risk of surface water flooding (SWF) in England is already high and its frequency severity projected to increase the future. SWF generally occurs due intense, highly localised rainfall, which challenging forecast with sufficient accuracy take proactive action ahead flood events. Being able manage effectively lies improved rainfall products, better communication uncertainty building capacity...
