We consider a cooperative system to provide power saving, quality of service, and coverage extension over in-home power line communications (PLC) networks. We focus on a cooperative relay scheme, where the communication between source and destination nodes follows an opportunistic time division decode and forward (ODF) protocol. At the physical layer we assume the use of a multi-carrier scheme. We...
We consider the use of a relay to provide capacity improvements and range extension for in-home power line communication networks. In particular, we focus on opportunistic relaying where the relay is exploited only if it provides improved capacity w.r.t. the use of direct transmission between the source and the destination. The relay applies a decode and forward scheme and the channel is shared in...
This paper propose a new and effective communication protocol for implementation of automatic meter reading (AMR) systems using power line communication (PLC). The proposed hybrid contention-polling protocol involves request broadcasting by the data concentrator (DC) and subsequent rebroadcasting by higher level meters up till the third hop using a novel dual purpose packet for transmission. The proposed...
