Channel access mechanism based on equally allocation of protocol sequence for VANET
In order to improve the throughput performance in VANET, a channel access mechanism based on equally al-location (EA) of protocol sequence was proposed. For highway scenery, the proposed mechanism re-planed the mapping of traffic channel allocation of IEEE 802.11p to competition zone. In addition, t...

| description | In order to improve the throughput performance in VANET, a channel access mechanism based on equally al-location (EA) of protocol sequence was proposed. For highway scenery, the proposed mechanism re-planed the mapping of traffic channel allocation of IEEE 802.11p to competition zone. In addition, the frame structure was also redesigned according to the characteristic of user irrepressible protocol sequence. A few bits of data were used to find out the number of nodes in the competition zone. Cyclic polling allocation was proposed to allocate the protocol sequences under average meaning. The theoretical throughput expression is derived and proved to be correct by simulation. It is also verified that the throughput of EA is more superior to classical met in a sparser distributed network or a higher PHY data rate. Equally importantly, EA can also keep relative low net overhead and available fairness about channel access of the nodes. |
