A CSMA/CD Compatible MAC for Real-Time Transmissions Based on Varying Collision Intervals
نویسندگان
چکیده
This paper suggests a CSMA/CD compatible MAC protocol for real time transmissions in a Home or Small O ce Local Area Network. The protocol allows high priority devices transmitting real time tra c such as digital video and audio to communicate with each other with guaranteed low delay and jitter, across an existing Ethernet, which is supporting standard Ethernet devices such as PCs, printers and ISDN routers. A device implementing the new MAC can also communicate across the Ethernet with the standard devices.

The new MAC is based on the distributed assignment of special TAG numbers to the stations transmitting real-time traffic. These TAG numbers determine a Round Robin order of transmissions amon...
متن کاملComparison of IEEE 802.3 & IEEE802.11 MAC Protocol EEET1149 LOCAL AND METROPOLITAN AREA NETWORKS LECTURER:
The IEEE 802.3 and 802.11 standards are used to define CSMA/CD (Carrier Sense Multiple Access with Collision Detection) based on the Ethernet LAN (Local Area Networks) and Wireless LAN (WLAN) protocol, respectively. This report deals with the comparison of IEEE 802.3 and IEEE802.11 MAC protocol in terms of the physical and medium access control (MAC) layer. CSMA/CD Ethernet-based protocol is th...

متن کاملThe Effect of Exerting Adequate Persistence in Collision Avoidance Protocols
Many medium-access control (MAC) protocols based on a collision-avoidance handshake between the sender and the receiver have been proposed for wireless networks. To date, however, the analysis of these protocols has assumed non-persistent strategies in sending control packets for collision avoidance. The persistent strategies discussed in the past for CSMA and CSMA/CD provide performance improv...
متن کاملMac for Physical-Layer Network Coding in VANETs
In this paper, the authors present VPNC-MAC, a PNC-based MAC protocol for efficient and reliable periodic beacon broadcasts in VANETs. In addition to PNC-based scheduled transmissions, VPNC-MAC makes use of CSMA/CA to ensure fairness and flexibility with transmissions from CSMA-based nodes. VPNC-MAC consists of two phases: In the setup phase, a quasi-optimal mechanism of selecting a relay node ...
