In this paper, we focus on the static routing, spectrum, and core assignment (RSCA) problem in space-division multiplexing (SDM)-based elastic optical networks (EONs) with multi-core fiber (MCF). RSCA problems, it is a challenging task to control inter-core interference, called crosstalk (XT), within an acceptable level simultaneously maximize spectrum utilization. We first consider XT worst interference scenario (i.e., XT-unaware), which can simplify problem. scenario, formulate using...
Edge computing has been introduced as a promising technology for real-time video streaming systems. However, due to the lack of automatic incentives and limitation resources, traditional edge performs poorly in nowadays scenarios. To handle these two challenges, we propose framework <underline xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">J</u> oint xmlns:xlink="http://www.w3.org/1999/xlink">I</u> ncentive design...
Self-supervised video hashing (SSVH) is a practical task in indexing and retrieval. Although Transformers are predominant SSVH for their impressive temporal modeling capabilities, they often suffer from computational memory inefficiencies. Drawing inspiration Mamba, an advanced state-space model, we explore its potential to achieve better balance between efficacy efficiency. We introduce S5VH, Mamba-based model with improved self-supervised learning paradigm. Specifically, design...

Offloading computation based on mobile edge computing paradigms can augment the computational capabilities of resource-scarce devices. However, capacity limitations servers constrain performance improvement achieved through offloading. In this article, we consider a three-tier offloading schema with multiple users, servers, and cloud servers. Computation be offloaded from devices to or further remote if necessary. Since number connected will share common wireless communication network, which...

We formulate as an optimization problem. Then propose two optimal...
Wavelength-division multiplexing (WDM) technology has emerged as a promising for backbone networks. The optical layer based on WDM provides routing services to the upper layers such packet-switching and time-division (TDM) over generalized multiprotocol label-switching (GMPLS) paradigm. set of all-optical communication channels (lightpaths) in defines logical topology applications. Since traffic demand applications fluctuates from time time, it is required reconfigure underlying accordingly....
In space division multiplexing (SDM) systems, the spatial dimensions can be divided into one or several group(s). Spatial in same group jointly switched based on joint switching (J-Sw)/fractional (FrJ-Sw), resulting less wavelength selective switch (WSS) usage. Additionally, optical carriers frequency of these share a single laser source. Therefore, coarser (switching) granularity reduce usage both WSSs and lasers. However, compared to case finer granularity, this scenario leads more guard...
To keep pace with the rapidly increasing network traffic demand anticipated in coming years, space-division multiplexing (SDM) has become a promising technology for overcoming limitations of current wavelength-division based optical networks. The key advantage SDM-based transmission is that it increases capacity by extending available spatial dimensions. In this context, several innovative technologies have been proposed to support spatially and spectrally flexible all-optical transmission....
Network function virtualization (NFV) is a new network architecture concept that simplifies the deployment of services and improves service management. However, it challenging for provider (NSP) to decide where place virtual functions (VNFs). Most previous studies have considered only single-chain services, wherein VNFs request are executed in sequence. In contrast approaches, we consider more general practical situations which can be parallel represented as forwarding graph. Our objective...
