An Index-Bit Enabled Transmission Scheme with Dynamic Balancing
2020
To tackle the traffic congestion over channels, we propose a new transmission scheme, which is powered by the concept of index bit (IB), to increase the transmission efficiency. In this letter, the item of bit-unit (BU) is adopted to replace that of IP packet. Explicitly, every BU is divided into two parts: one is IB, and the other is conventional bit (CB). In specific, every IB is of equal length with its value representing the length of the corresponding CB. At the transmitter side, a storage is prepared for caching CBs temporarily, and has been divided into multiple sub-buffers in advance. Each CB is loaded into certain sub-buffer according to its IB, which is hidden during storing and transmission. To augment the benefit, a dynamic balancing method is proposed to adjust the width of each sub-buffer iteratively. Our numerical results demonstrate the achieved transmission efficiency gain. With the dynamic adjustment continues deeply, the utility function is increased in fluctuation to a saturated level.
