Abstract
The development and implication of medium-access-control (MAC) and logical-link-control (LLC) protocols for a low-cost power-line local area network (LAN) is described. A hub polling scheme is developed for use in the MAC sublayer. For the LLC sublayer, a modified version of the IEEE 802.2 standard has been adopted. Some measurements and a performance evaluation of throughput and delay are presented and discussed. Using prototype 14400-b/s power-line modems, it is found that the design and implementation of the protocols on the Sun workstation provides a reasonable throughput and response time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
