A Performance Study of EY-NPMA for Medium Access in Power Line Communications

摘要

Power Line Communications provide an efficient and inexpensive way for the creation of access or in-house networks, especially in areas where there is no dedicated preexisting cabling for communications. The choice of a suitable medium access scheme is imperative, since the MAC is the final arbiter of the efficient usage of the available network resources or not. In this paper we present a modified version of the EY-NPMA medium access scheme for power line communications, showing through simulation trials the very good characteristics of the proposed scheme.
