Synthesizing Existing CSMA and TDMA Based MAC Protocols for VANETs
Sensors, 2017 Many Carrier Sense Multiple Access (CSMA) and Time Division Multiple Access (TDMA) based medium access control (MAC) protocols for vehicular ad hoc networks (VANETs) have been proposed recently. Contrary to the common perception that they are competitors,

Local Multicoloring Algorithms: Computing a Nearly-Optimal TDMA Schedule in Constant Time [PDF]
, 2009 The described multicoloring problem has direct applications in the context of wireless ad hoc and sensor networks. In order to coordinate the access to the shared wireless medium, the nodes of such a network need to employ some medium access control (MAC)

InfoMat, Volume 8, Issue 4, April 2026.Current brain‐inspired computing chips require complex additional circuits to operate effectively, making them bulky and inefficient. We have created a single adjustable artificial neuron device made from MoS2 that can dynamically modulate its behavior on demand, eliminating the need for extra circuits and enabling it to process different types of ...

Advanced Science, Volume 13, Issue 13, 3 March 2026.An ultralight, multilayer anisotropic tactile sensor—an artificial Pacinian corpuscle—exhibits ultrahigh tangential sensitivity (1022 kPa−1) and spatiotemporal sensing. It discriminates static, sliding, and rolling contacts, detects incipient stick–slip via high‑frequency signatures, and enhances robotic touch (100%/98.18% accuracy for active/passive ...

A Review of Software for Designing and Operating Quantum Networks
Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.A quantum network can be organized following a three‐plane abstraction: infrastructure, logical, and control. A taxonomy of the network functions of the control plane is proposed, and the state of the art in software for quantum networks is discussed. A guide for future directions on software development is provided.
