System and Methods for Distributed Medium Access Control and QOS Scheduling in Mobile Ad-Hoc Networks

摘要

A communication device and method are provided for communicating with a receiving device over a channel within a mobile ad-hoc network. The receiving device includes a clear-to-send (CTS) packet generating portion that can generate and a CTS packet based on a parameter of the channel and that can transmit the CTS packet over the channel. The communication device includes a transmitter portion, a receiver portion and a management portion. The transmitter portion can transmit information into the channel. The receiver portion can receive information from the channel. The management portion includes a request-to-send (RTS) packet generating portion, a CTS packet receiving portion, a threshold database, a comparator and an RES packet generating portion. The management portion is in communication with the transmitter portion and the receiver portion. The RTS packet generating portion can generate a RTS packet and can provide the RTS packet to the transmitter portion. The transmitter portion can transmit the RTS packet to the receiving device by way of the channel. The receiver portion can receive the CTS packet from the receiving device by way of the channel and can provide the CTS packet to the CTS packet receiving portion. The threshold database can store a threshold value for the parameter of the channel and can provide the threshold value to the comparator. The CTS packet receiving portion can provide channel parameter information, to the comparator, based on the CTS packet. The comparator can compare the threshold value and the channel parameter information and can generate an instruction signal based on the comparison. The RES packet generating portion can generate an RES packet based on the instruction signal and can provide the RES packet to the transmitter portion.
