Summary: The number of mobile devices accessing wireless networks is increasing rapidly due to the advancement of sensors and wireless communication technology. It is expected that mobile data traffic will continue to rise in the coming years. In order to meet the demands of the Internet of Things, smart homes, and more sophisticated applications, a new cellular network paradigm is being developed. Offloading computation to distant clouds or nearby mobile devices has improved the performance of mobile devices, and D2D collaboration can further reduce task delays. However, the variation in performance capabilities of edge nodes affects the task offloading performance. This paper proposes a new method for D2D communication by enabling edge nodes to exchange data samples, which reduces time delay and demonstrates better performance compared to traditional algorithms.

Summary: D2D communication is an essential part of 5G cellular networks, allowing close-proximity devices to establish direct communication with advantages such as reduced latency, high data rates, range extension, and cellular offloading. Efficient device discovery is the first step in establishing a D2D session, leading to efficient D2D communication. This work considers six distinct scenarios for initiating D2D communication, taking into account their merits, demerits, limitations, and optimization parameters. Based on the signal flow, D2D communication procedures including device discovery, resource allocation, and session teardown have been formulated for each scenario. Finally, latency evaluation based on propagation and processing delays is conducted for each scenario.

Summary: In this study, an integrated sensing and communication (ISAC) aided dynamic resource allocation is proposed for random access (RA) in Internet-of-Things (IoT) oriented satellite terrestrial relay networks (STRNs). The proposed ISAC aided RA architecture consists of sensing phase and RA phase, where relays sense the number of active users and assist RA accordingly. The active users are grouped into orthogonal clusters in the spectrum domain. A dynamic resource allocation optimization problem is solved to allocate bandwidth to each cluster based on the number of intra-cluster active users, ensuring optimal uplink RA and maximum system throughput.

Summary: Rate-splitting multiple access (RSMA) is investigated for the resource allocation problem in a downlink multi-user and multiple-input single-output (MU-MISO) RSMA system with successive interference cancellation (SIC) errors for ultra-reliable and low-latency communications (URLLC). Single-carrier RSMA (SC-RSMA) and multicarrier RSMA (MC-RSMA) schemes are proposed with optimization algorithms to maximize the effective throughput (ET) and solve the non-convex optimization problem. Simulation results demonstrate that RSMA schemes can achieve higher ET and improve latency and reliability compared to non-orthogonal multiple access (NOMA) schemes in the URLLC scenario.

The study demonstrates that GEC guarantees better concentration of cache storage size than existing methods, with significant reductions in required cache size for both uniform and non-uniform spatial traffic.

Summary: TCP is a key Internet protocol, but its design limits its ability to react to network events. This paper proposes TCP Path Changer (TPC), which incorporates eBPF programs into the Linux TCP/IP stack to make TCP more agile. Experimental results demonstrate that TPC can quickly reroute TCP connections around failures and monitor and reroute connections with high round-trip-time, providing significant performance benefits.

Summary: This paper presents a rational approach to reduce the computational and communication complexities of lossless point-to-point compression for computation with side information. By using b-fold coloring of characteristic graphs, the approach provides a linear programming relaxation to the traditional coloring method and achieves coding at a fine-grained granularity. The lower bound for compression is derived through generalizing the notion of graph entropy.
