Unmanned aerial vehicles (UAVs) have recently rapidly grown to facilitate a wide range of innovative applications that can fundamentally change the way cyber-physical systems (CPSs) are designed. CPSs modern generation with synergic cooperation between computational and physical potentials interact humans through several new mechanisms. The main advantages using UAVs in CPS application is their exceptional features, including mobility, dynamism, effortless deployment, adaptive altitude,...

In this paper, we study distributed power allocation for multiflow carrier aggregation in cognitive cellular networks. Our approach differs from the conventional water filling (WF) algorithm since deal with heterogeneous fading channels, wherein all of Lagrange multipliers are not handled equally over cells. The control solution is carried out channels that considered nonidentically Nakagami-m channels. We first formulate optimization problem, and then solve it using alternating direction...

Vehicle-to-vehicle (V2V) communications have recently received growing attentions due to the fact that it enables dynamic wireless data exchange between nearby vehicles, offering opportunity for safety improvements and information sharing. In this paper, we investigate performance analysis of a two-way amplify-and-forward (AF) multi-relay cooperative V2V communication networks with MPSK modulation, two cases where relays are vehicles or they access-points road. mobile-to-mobile system...

In this paper, we present an adaptive wireless communication system with energy harvesting relay where, two sources wish to send data a destination via that utilizes hierarchical constellation. our proposed model, the based on channel side information, adaptively decides between sending information bits of each source and saving energy, which leads three modes cooperation. first mode, after successfully decoding sources, puts bit lower amplitude in layer other second constellation only...

In this paper, we investigate relay-sharing in cognitive radio (CR) networks to improve the secondary user's (SU's) performance presence of interference. It is assumed that relay shared simultaneously between both primary user (PU) and SU by using hierarchical modulation at node while mapping PU's SU's symbols onto two different layers constellation. The proposed scheme relies on power adjusting, where adjustment based channel side information (CSI) tolerable interference limit PU....

In this paper, a new watermarking method based on spread spectrum technique, which we call capacious (CSS) is proposed. method, unlike the traditional (TSS), more than one pseudo noise (PN) sequence will be deployed. Also, novel to produce orthogonal PN-sequences achieved. Moreover, it shown that with utilizing approach, for same capacity, reconstruction error probability would less of TSS method.

Sharing a relay in cognitive radio (CR) networks order to enhance the secondary user's (SU's) performance an interference‐limited scheme is investigated. It assumed, by utilising hierarchical modulation, shared used simultaneously between both primary user (PU) and SU. The proposed relies on power adaptation rate scheduling. Based channel side information tolerable interference limitation at PU, SU adapts its transmission data rates are regulated PU's status channels condition. Theoretical...

Three different improvement concepts were identified as suitable for the environment. Lean, Six Sigma, Theory Constraints (TOC). Lean was retained being most due its low cost, focus on quality, built continuous process. In study, applied address three top issues. A baseline established...

In this paper, we investigate the performance of energy harvesting relay-aided cooperative system wherein, source node transmits hierarchical signal to relay and destination nodes. But, since in networks relays are often nearer than destination, is able decode multi-resolution whereas, only capable detecting most important layer modulation signal. Moreover, subject be lack with certain probability thus, not being cooperate at every communication instances. This, turn degrades overall...
