Medium Access Control in Ultra-Wideband Wireless Networks

Medium Access Control for Wireless Sensor Networks based on Impulse Radio Ultra Wideband

This paper describes a detailed performance evaluation of distributed Medium Access Control (MAC) protocols for Wireless Sensor Networks based on Impulse Radio Ultra Wideband (IR-UWB) Physical layer (PHY). Two main classes of Medium Access Control protocol have been considered: Slotted and UnSlotted with reliability. The reliability is based on Automatic Repeat ReQuest (ARQ). The performance ev...

Multi-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

Medium Access Control in Impulse-Based Ultra Wideband Ad Hoc and Sensor Networks

A Novel Framework for Medium Access Control in Ultra-Wideband Ad Hoc Networks

Ultra-wideband (UWB) communication is becoming an important technology for future Wireless Personal Area Networks (WPANs). A critical challenge in UWB system design is that a receiver usually needs tens of micro-seconds or even tens of milliseconds to synchronize with transmitted signals, known as timing acquisition problem. Such a long synchronization time will cause significant overhead, sinc...
