Enabling future mobile wireless networks edge with adaptive access control and caching

无线网络（6 G）的长期愿景为触觉互联网、联网车辆和工业物联网的网络设计提供了一种新颖的方法，这对支持以下内容提出了独特的要求：1）同时实现高数据速率和超可靠低延迟（URLLC）通信的多个性能目标（例如，用于沉浸式虚拟现实（IVR）），以及2）包括触觉、语音和视频的异构业务。毫米波（mmWave）无线电在蜂窝和WLAN网络中均采用，用于高数据速率（高达Gbps）通信。它采用定向波束成形来实现空间分集，这对低延迟也至关重要。然而，实现URLLC是具有挑战性的，因为它需要沿着通信路径沿着的所有功能的对齐以在队列中工作，从而提供最佳延迟控制。该建议的重点是在通信路径的两个阶段上设计URLLC的网络功能：1）用于信道访问的介质访问控制，以及2）用于内容访问的缓存。在工业中，无线定位和传感器网络连接传感器、控制器和执行器，用于执行工业自动化任务，如对象跟踪、库存控制、故障诊断、应急响应、视频监控和机器人控制。这需要非周期性的传感数据传输;高速视频流;以及定位、紧急情况、触觉和故障诊断数据的超可靠低延迟传输。在工业设备中，信号传播经历深度衰落。我们计划开发一个自适应媒体访问控制方案。它结合了集群和调度，适应节点的移动性，非周期性的流量激增，可变的睡眠时间。用于毫米波通信的定向波束成形天线减轻了瞬态衰落，但由于本研究中解决的耳聋问题，它影响了用于定位和簇头的读取器的选择。 信息中心网络（ICN）是一种新的网络设计范例，其允许通过无处不在的网内缓存在网络内分发内容，并且通过内容路由使其沿着沿着最短路径可访问。ICN在网络中集成了缓存，使路由器不仅可以转发内容，还可以缓存内容，以减少未来的请求延迟。对移动性（位置无关内容请求）和多播（通过请求聚合将内容转发到多个下游路由器）的支持是ICN固有的。ICN中无处不在的网络内缓存的风险是其对安全威胁的敏感性。ICN中的安全威胁更加严重和复杂，因为它们的目标是网络（路由）和计算（缓存）功能和资源。该提案的另一个目标是开发用于低延迟内容访问的安全分层ICN缓存。

The long-term vision of wireless networks (6G) warrants a novel approach to network design for Tactile Internet, connected vehicles and Industrial Internet of Things, which poses unique requirements to support: 1) multiple performance objectives of high data rate and ultrareliable low latency (URLLC) communication at the same time (e.g. for immersive virtual reality (IVR)), and 2) heterogeneous traffic including haptic, voice and video. The millimeter wave (mmWave) radio is adopted in both cellular and WLAN networks for high data rate (up to Gbps) communication. It employs directional beamforming for spatial diversity that is also vital for low latency. However, achieving URLLC is challenging because it needs alignment of all the functions along the communication path to work in cohort to provide optimal delay control. The focus of this proposal is on the design of network functions for URLLC at two stages of communication path: 1) medium access control for channel access, and 2) caching for content access. Both are critical for URLLC because they can cause significant delays through excessive channel contention and long content download path. In industries, wireless positioning and sensor network connects sensors, controllers, and actuators for industrial automation tasks such as object tracking, inventory control, fault diagnosis, emergency response, video monitoring, and robotic control. This requires aperiodic transmission of sensing data; high rate video streaming; and ultrareliable low latency transmission of localization, emergency, haptic and fault diagnostic data. In industrial plants signal propagation experiences deep fading. We plan to develop an adaptive medium access control scheme. It incorporates clustering and scheduling that adapt to node mobility, aperiodic traffic surge, and variable sleep time. The directional beamforming antenna for mmWave communication mitigates transient fading, but it impacts the selection of readers for localization and cluster head because of Deafness that are addressed in this research. Information Centric Network (ICN) is a new paradigm of network design that allows distribution of content inside the network through ubiquitous in-network caching and makes it accessible along the shortest path through content routing. The ICN integrates caching in the network by enabling the routers to not only forward the content but also cache it to reduce future request latency. The support for mobility (location independent content request) and multicast (forwarding content to multiple downstream routers through request aggregation) is intrinsic to ICN. The risk of ubiquitous in-network caching in ICN is its susceptibility to security threats. Security threats are more severe and complex in ICN because their targets are both networking (routing) and computing (caching) functions and resources. Another goal of this proposal is to develop a secure hierarchical ICN caching for low latency content access.
