Providing Quality of Service (QoS) for sophisticated and QoS-constraining applications (e.g. video-based applications, multimedia services, and high speed data services) and ensuring continuous connectivity for universal mobile stations (UMS) in heterogeneous networks are important issues in the design of fourth generation (4G) networks. The latter will utilize multiple radio access technologie...

Next Generation Public Safety Communication (PSC) is a crucial topic for research community worldwide. There is a strong need of research towards Public Safety user requirements, such as mobility and security support in a system architecture able to interconnect heterogeneous access technologies belonging to different agencies and jurisdiction. In this work, a combination of Proxy Mobile IPv6 (...

Abstract In recent years, with the development of long-distance communication, encryption method has become one crucial topics. Quantum advantage no-cloning theorem, is far more secure than traditional communication and could be a key in encrypted communication. this paper, we simulate whole process quantum encryption, satellite-relayed distribution, transmission information, decoding received ...

Contrastive deep clustering has recently gained significant attention with its ability of joint contrastive learning and via neural networks. Despite the rapid progress, previous works mostly require both positive negative sample pairs for clustering, which rely on a relative large batch-size. Moreover, they typically adopt two-stream architecture two augmented views, overlook possibility poten...

The extraction of road network is an emerging area in information extraction from high-resolution satellite images (HRSI). It is also an interesting field that incorporates various tactics to achieve road network. The process of road detection from remote sensing images is quite complex, due to the presence of various noises. These noises could be the vehicles, crossing lines and toll bridges. ...

We propose a framework for single-source, satellite-based multicast dissemination of bulk files. The framework trades off between reception delay and bandwidth usage and coexists with terrestrial background network traffic; specifically TCP traffic utilizing a short-term congestion control mechanism. The framework consists of two major components: 1) a multicast rate scheduling mechanism that u...
