Reservation MAC Protocols for Powerline Communications

چکیده
In this paper suitable MAC protocols for the implementation in PLC access networks are studied. We propose a logical model for the investigation of the MAC layer according to the applied transmission methods in the PLC systems and to the used telecommunication services. The impulsive noise has a big impact on the error behavior of the transmission, but there are various possibilities to do deal with this problem (FEC, ARQ, ...). In spite of that, the investigation of the MAC layer has to include several disturbance scenarios which are specified in this work. We propose the reservation MAC protocols to be applied to the PLC access networks, because they are suitable to carry hybrid traffic with variable data rates ensuring a high network utilization. Two basic reservation MAC protocols, ALOHA random access and polling based dedicated access, are analyzed. We also discuss several possibilities for the protocol improvement.

متن کاملPerformance Analysis of Reservation MAC Protocols for Ad-hoc Networks
Multimedia and real-time applications require bandwidth guarantees, which may be achieved by resource reservation. However, resource reservation in ad-hoc networks is a very challenging task due to the instability of radio channels, node mobility and lack of coordination between mobile nodes. Proposed reservation MAC protocols like CATA, FPRP, R-CSMA and SRMA/PA have limitations and are suitabl...

Multimedia and real-time applications require bandwidth guarantees, which may be achieved by resource reservation. Several researches were done to propose efficient reservation MAC protocols for ad-hoc networks. In these schemes, channel is segmented into super-frames composed of fixed number of slots. They allocate slots to each traffic source, and make sure that neighbor nodes record the rese...
