In wireless multihop transmissions of data messages, concurrent data message forwarding by 2-hop neighbor intermediate wireless nodes are prohibited due to collision avoidance between these data messages. However, depending on the distances between neighbor intermediate wireless nodes, no collision concurrent data message forwarding by 2-hop neighbor intermediate wireless nodes is realized due to the capture effects. Therefore, with more partial sequences of intermediate wireless nodes allowing the concurrent data message forwarding, shorter end-to-end transmission delay and higher throughput of data messages are expected. This paper proposes a more concurrent data message transmission method with collision avoidance in consideration of the capture effects and a routing protocol detecting a wireless multihop forwarding route allowing the concurrent data message transmissions. Results of simulation experiments suggest the improvement of end-to-end throughput of data messages due to the concurrent data message.

摘要

In wireless multihop transmissions of data messages, concurrent data message forwarding by 2-hop neighbor intermediate wireless nodes are prohibited due to collision avoidance between these data messages. However, depending on the distances between neighbor intermediate wireless nodes, no collision concurrent data message forwarding by 2-hop neighbor intermediate wireless nodes is realized due to the capture effects. Therefore, with more partial sequences of intermediate wireless nodes allowing the concurrent data message forwarding, shorter end-to-end transmission delay and higher throughput of data messages are expected. This paper proposes a more concurrent data message transmission method with collision avoidance in consideration of the capture effects and a routing protocol detecting a wireless multihop forwarding route allowing the concurrent data message transmissions. Results of simulation experiments suggest the improvement of end-to-end throughput of data messages due to the concurrent data message.
