In this paper, the authors study real-time scalable video broadcast over wireless networks using Instantly Decodable Network Coding (IDNC). Such real-time scalable videos have hard deadline and impose a decoding order on the video layers. They first derive the upper bound on the probability that the individual completion times of all receivers meet the deadline. ...
In this paper, the authors study the Gaussian Two-Way Relay Channel (GTWRC), where two nodes exchange their messages with the help of a half-duplex relay. The authors investigate a cooperative transmission protocol, consisting of four phases: Multiple Accesses (MA) phase, broadcast phase and two cooperative phases. For this setup, they propose a new transmission scheme ...
Sink mobility is one of the most effective solutions for improving lifetime and has been widely investigated for the last decade. Algorithms for single-sink mobility are not directly applied to the multiple-sink case due to the latter’s specific challenges. Most of the approaches proposed in the literature use mathematical programming techniques to solve the multiple-sink ...
Without doubt the lure of high resolution videos along with a deeply engaging user interface is an irresistible attraction for almost all gamers across the world. Sales of video games are projected to cross more than billion in the coming years. With Internet speeds in certain countries climbing into the 3G and the newer 4G, ...
According to the loss network problems caused by limited resources and environment interference factors, they presented a survivability mechanism based on mobility prediction and based on the topological evolution of cloud computing Wireless Multimedia Sensor Network (WMSN). First, based on cooperative neural network and opportunity Markov chain model, the multimedia mobile sensor node state and ...
Spectrum sensing plays a significant role in enabling utilization of spectrum holes by unlicensed Secondary Users (SUs) in Cognitive Radio Networks (CRNs). Most of the related work concerning spectrum sensing has focused on sensing carried out by incoming Secondary Users (SUs) aiming at locating spectrum opportunities. However, in order to appropriately protect returning licensed Primary ...
A Mobile Ad hoc NETwork (MANET) is a group of autonomous mobile nodes that wirelessly communicate with each other to form a wireless dynamic topology network. It works without requiring any centralized pre-existing administration units (infrastructure less network). There are many studies that focus on improving source-destination route stability and lifetime by modifying the existing ...
With an explosive growth of mobile cloud and Internet of Things (IoTs) technologies, the Mobile Cloud IoT (MCIoT) concept has become a new trend for the future Internet. MCIoT paradigm extends the existing facility of computing process to different mobile applications executing in mobile and portable devices. In this paper, the authors provide a new ...
Recently, emerging IoT cloud systems create numerous opportunities for a variety of stakeholders in terms of optimizing their existing business processes, as well as developing novel cross-organization and cross-domain applications. However, developers of such systems face a plethora of challenges, mainly due to complex dependencies between the application business logic and the underlying IoT cloud ...
Opportunistic routing has gained much attention as a new and promising approach to relay packets in wireless mesh networks. The collaboration of intermediate nodes to deliver packets without a predetermined route, using the broadcast nature of wireless channel, increases the transmission reliability and network throughput. Nevertheless, such characteristics make the process of admission control even ...
