We explore the performance of coded caching in a SISO BC setting where some users have higher link capacities than others. Focusing on a binary and fixed topological model where strong links have a fixed normalized capacity 1, and where weak links have reduced normalized capacity T < 1, we identify — as a function of the cache size and T — the optimal throughput performance, within a factor of...
In heterogeneous network environment, it is important to choose an appropriate access network for a Multimode Mobile Terminal (MMT). Currently, there are some methods proposed to make network access selection decision. However, those methods didn't consider some dynamic attributes and could not offer effective handoff strategies. In this paper, we introduce an Intelligence Access Selection Scheme...
We propose an efficient MAC protocol for OFDMA PONs that eliminates the synchronization requirement of ONUs and also exploits the statistical multiplexing gain among traffic of all ONUs for high performances in throughput and delay.
With the rapid increase of real-time applications, jitter, delay, and throughput have become the three important QoS criteria in the scheduling of input-queued (IQ) switches with virtual output queues (VOQ). In this paper, we propose a novel frame-based scheduling algorithm, referred to as dichotomy slot allocation (DSA), to achieve high throughput, bounded delay, and bounded jitter. DSA possesses...
