一种基于邻近度的电力线Ad-hoc重传方案LAN
A Proximity based Retransmission Scheme for Power Line Ad-hoc LAN
摘要：
电力线作为数据传输的一种替代方式正在被探索，并得到了一定程度的应用。但从数据传输的角度来看，电力线作为一种信道是高度动态的，因此不太适合。为了将办公室或家庭布线系统转换为局域网（LAN），需要对现有协议进行自适应改变。本文提出了一种时隙传输方案，该方案通过物理感知介质来发现可用时隙。发送器-接收器对的公共可用时隙用于通信。但是这些将不能确保安全的分组传递，因为分组可能在从发送者到接收者的传播过程中被破坏。因此，我们还建议了一个基于邻近度的重传方案，其中局域网中的每台机器都缓冲好的数据包，并且靠近接收机的机器在接收到NACK时停止。
英文摘要：
Power line as an alternative for data transmission is being explored, and also 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. To convert 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, a slotted transmission scheme is suggested, in which usable timeslots are found out by physically sensing the media. Common usable timeslots for the sender-receiver pair are used for communication. But these will not ensure safe packet delivery since packets may be corrupted on the way during propagation from sender to receiver. Therefore, we also suggest a proximity based retransmission scheme where each machine in the LAN, buffers good packet and machines close to the receiver retransmit on receiving a NACK.
