Dynamic Time Slot Partitioning for Multimedia Transmission in Two-Hop Cellular Networks

—In recent years, there has been an exponential increase in the number of mobile phone users. In addition, a significant growth in the demand for high-rate multimedia services over wireless networks, such as video conferencing, multimedia streaming, etc., was noted. Different solutions were proposed to support high quality high data-rate delivery to mobile users, including resource allocation techniques for packet radio-based next generation cellular networks. In this paper, an efficient time slot allocation method - Dynamic Time Slot Partitioning (DTSP) algorithm based on statistical multiplexing is proposed for a two-hop cellular architecture. In DTSP, the available bandwidth resources are increased by partitioning each time slot into several minislots; different number of minislots are allocated to different users. The DTSP algorithm is based on asynchronous time division multiplexing, wherein users with variable number of packets in their buffers can transmit data sequentially ...
