An Accelerated Peer-To-Peer (P2p) Communication Method Facilitated By Reusing Existing P2p Paths For Low-Power And Lossy Networks, Huimin She, Harbor Dong, Wenjia Wu, Nan Yi

Defensive Publications Series

The Wireless Smart Utility Networks (Wi-SUN) alliance promotes interoperable wireless standards-based solutions for Internet of Things (IoT) deployments, such as distributed automation (DA). For some applications, such as smart utility or smart city applications, it is desirable to provide optimized peer-to-peer (P2P) routing. However, for P2P traffic within a Destination Oriented Directed Acyclic Graph (DODAG), packets either have to be routed through a root in a non-storing mode or through a common ancestor in a storing mode. Techniques herein provide for locally reusing and distributing projected directed advertisement object (P-DAO) tracks. For example, when a node receives a P-DAO track …

Use Of Augmented Reality To Enable Comparisons Between Physical And Virtual Objects, Alexander James Faaborg, Brett Barros

Defensive Publications Series

Augmented reality (AR) shopping is typically thought of as the filling up of an empty space with virtual objects to assess the fit of that object to that space. This formulation ignores the portion of shopping that involves the replacement of an item. While a user can take a photo of an item, without an AR model of the item, the user cannot determine the fit or suitability of the item to their spaces. Current AR tools cannot identify and describe the key differences between what a user has and what the user wants to purchase. This disclosure describes techniques …

Use Of Per-Cpu Counters To Protect Kernel-Mode Processes On A Multicore Processor, Joel Agnel Fernandes

Defensive Publications Series

When user and kernel mode processes are scheduled to run simultaneously on the same physical processor core via simultaneous multithreading, processor vulnerabilities can result in sensitive data restricted to kernel-mode processes being leaked to user-mode processes. While disabling simultaneous multithreading or use of a scheduler that determines sequence of execution can prevent such leakage, these changes degrade processor performance. This disclosure describes the use of per-CPU counters to track when each physical core of a processor begins and ends the execution of a program thread running in the kernel mode. Upon detection of such a thread, the core is identified …
