Power line as an alternative for data transmission is being explored, andalso being used to a certain extent. But from the data transfer point of view,power line, as a channel is highly dynamic and hence not quite suitable. Toconvert the office or home wiring system to a Local Area Network (LAN),adaptive changes are to be made to the existing protocols. In this paper, aslotted transmission scheme is suggested, in which usable timeslots are foundout by physically sensing the media. Common usable timeslots for thesender-receiver pair are used for communication. But these will not ensure safepacket delivery since packets may be corrupted on the way during propagationfrom sender to receiver. Therefore, we also suggest a proximity basedretransmission scheme where each machine in the LAN, buffers good packet andmachines close to the receiver retransmit on receiving a NACK.
