Summary: This paper proposes a hop-by-hop bandwidth allocation framework for service function chains (SFCs) to guarantee delay QoS constraints. By modeling the traffic and using effective bandwidth theory to allocate bandwidth hop by hop, the performance of SFC deployment is evaluated using novel delay evaluation metrics. Finally, a heuristic algorithm is designed to solve the SFC deployment problem.

Summary: This paper proposes a routing protocol based on IEEE 802.15.4a that enhances the delay and energy efficiency in Wireless Sensor Networks (WSN) using two-hop information. The proposed scheme utilizes potential relay information (PRI) and preemptive neighborhood state index (NSI) algorithm to improve the performance of WSNs, and integrates proactive feedback technique to simplify the update of two-hop information. Simulation results validate the efficiency of the proposed scheme and demonstrate improvements in network lifetime, packet delivery ratio, end-to-end delay, and energy consumption over compared algorithms.

Summary: This paper investigates the potential of improving the end-to-end throughput of a multi-hop wireless network using wireless cut-through transmission based on in-band full-duplex technique. It is found that the achievable throughput is mainly determined by the cut-through mode, spatial reuse factor, protocol overhead, and channel rate. To improve the end-to-end throughput, a low-overhead distributed MAC protocol is designed, along with a transmit-delay mechanism and an algorithm to adaptively select transmission parameters.

Summary: A Wireless Sensor Network (WSN) is a new type of real-time embedded device that can be used for various applications that are impracticable for regular networking. WSN faces major issues with energy production of nodes that can influence system stability. Therefore, protocols and standards are needed to utilize constrained capacity and energy resources effectively. Clustering has proven to be an effective strategy for addressing power utilization and energy imbalance issues in WSN.

Summary: This paper focuses on the trade-off analysis between fixed-time stabilization and energy consumption for a type of nonlinear neural networks. By constructing a compound switching controller and utilizing inequality techniques, a sufficient condition is proposed to ensure fixed-time stabilization. An estimate of the upper bound of the energy consumed by the controller in the control process is provided. Furthermore, quantitative analysis of the trade-off between control time and energy consumption is studied. The results reveal that appropriate control parameters can balance the two indicators to achieve optimal control state.

Summary: To save energy, extend the lifespan of sensor devices, and provide reasonable packet delay time in IoT systems, it is important to design an efficient sleep mode energy-saving scheme. By analyzing the relationship among sleep procedure, energy consumption, lifetime, and packet delay time, a multi-hop-based energy-saving control scheme is proposed. It selects the power save class type adaptively, leading to reasonable energy consumption and proper packet delay time for sensor devices.

Summary: Mobile devices can store, communicate, and disseminate large data files across networks, but it is challenging in Delay Tolerant Networks due to lack of connectivity and short contacts among nodes. Existing protocols are not suitable for the data-intensive mobile era, so a large data routing protocol is proposed to chop data into chunks for forwarding, achieving a higher delivery rate compared to other routing strategies.
