Summary: This paper proposes a novel sleep-mode base station (BS) selection scheme called forced handover, which uses mobile stations as mobile relay stations to maximize the number of BSs in sleep mode. Forced handover is a concept that forces edge mobile stations to neighbor relay stations for energy saving and SINR improvement. The proposed energy saving scheme can be applied to micro and macro sleep modes as well as turning off the BSs. The performances of BS sleep mode schemes in various environments, such as small cell networks and different user distributions, are investigated.

Summary: The design of green cellular networking can reduce overall energy consumption cost-effectively, especially through the implementation of cell zooming and renewable energy resources. Utilizing solar energy for base stations can be cost-effective and reliable but requires feasibility assessment for photovoltaic schemes. Therefore, cellular operators need to consider both technical and economic factors before implementing solar-powered BSs.

Summary: In this study, we investigate the allocation of green resources in mobile edge computing systems to minimize the energy consumption of users. We propose a joint search and Successive Convex Approximation scheme to optimize task offloading decisions, transmit power, and computation resource allocation. By addressing the non-convex mixed-integer nonlinear programming problem, we develop a heuristic scheme to reduce computational complexity and obtain sub-optimal solutions through fixed task offloading decisions and exhaustive search.

Summary: In this paper, a delayed SEIR model is formulated to describe malware propagation on mobile wireless sensor networks. The basic reproduction number is calculated using the next generation matrix method, and the impact of time delay due to the incubation period of malware is discussed using the eigenvalue method. Additionally, the properties of Hopf bifurcation are derived using the center manifold method. An optimal control strategy is presented to minimize the number of infectious nodes and the cost of detoxication, which is based on constructing a suitable Hamiltonian function. Numerical calculations are conducted to validate the theoretical findings.

Summary: In this article, a novel energy efficiency metric called integrated relative EE (IREE) is proposed, which can jointly measure the traffic profiles and network capacities from the perspective of energy efficiency. The traditional EE metric fails to capture the variations in traffic and capacity of next-generation wireless networks. Through analytical and numerical results, it is shown that the proposed IREE metric is able to capture the wireless traffic and capacity mismatch property, which is significantly different from the conventional EE metric. The IREE-oriented design or deployment strategy can be considered as a useful guidance for future energy-efficient network design.

Summary: This paper proposes an end-to-end scheme, VSiM, for supporting mobile video streaming applications in heterogeneous wireless networks. It allocates bottleneck bandwidth among multiple users based on their mobility profiles and Quality of Experience (QoE)-related knowledge to achieve max-min QoE fairness. The scheme also improves the QoE of buffer-sensitive clients using a novel server push strategy based on HTTP/3 protocol.
