To exchange information between two sources in a two-way relaying network with multiple potential relays, most researches focus on two-hop relay system with single-relay-selection (SRS) scheme. Comparing with SRS scheme, the authors first design a paired-relay-selection (PRS) scheme in which a pair of `best’ relays broadcast network-coded information to other nodes (source or relay). They […]

Design of rectangular microstrip patch antenna based on Artificial Neural Network algorithm
The Design of Rectangular Microstrip Patch Antenna using Artificial Neural Network (ANN) has been presented. This paper used Feed Forward Back Propagation Algorithm (FFBPN), Resilient Back-propagation (RPROP), Levenberg-Marquardt (LM) and Radial Basis functions (RBF) of ANN to obtain the resonant frequency of rectangular microstrip patch antenna. The model of ANN algorithm was developed and implemented […]

Outage Probability of Energy Harvesting Relay-aided Cooperative Networks Over Rayleigh Fading Channel
Energy harvesting technique is a potential way for relay node energy supply in cooperative networks in the respect of deployment flexibility and maintenance charge reduction. However, unlike traditional power source, it is intuitive that the fluctuation of harvested energy flow can degrade the benefit resulted from relay-aided cooperative transmission. To this end, this paper focuses […]
Read moreThis paper presents a novel change detection approach for synthetic aperture radar images based on deep learning. The approach accomplishes the detection of the changed and unchanged areas by designing a deep neural network. The main guideline is to produce a change detection map directly from two images with the trained deep neural network. The […]

Full-Duplex Spectrum-Sensing and MAC-Protocol for Multichannel Nontime-Slotted Cognitive Radio Networks
Because of the asynchronization between primary and secondary wireless networks, the synchronization between primary users (PUs) and secondary users (SUs) can be hardly guaranteed in nontime-slotted cognitive radio networks (CRNs). In this paper, we propose a novel framework for multichannel nontime-slotted CRNs, where the PUs randomly access and leave the licensed channels. Since the PUs […]

Minimization of CSI Feedback Dimension for Interference Alignment in MIMO Interference Multicast Networks
It is well-known that interference alignment (IA) can achieve substantial theoretical gains in multiple-input multiple-output (MIMO) networks. However, the conventional works usually assume the full channel state information (CSI) is available at the transmitter side, which would create a overwhelming CSI feedback overhead for practical frequency-division duplexing (FDD) wireless systems. To implement IA in practice, […]
Read moreIn mobile cloud computing systems, cloud computing has a significant impact on wireless networks. Cloud computing and wireless networks have traditionally been addressed separately in the literature. In this paper, we jointly study the operations of cloud computing and wireless networks in mobile computing environments, where the objective is to improve the end-to-end performances of […]
Read moreMeasurement of chlorophyll concentration is gaining more-and-more importance in evaluating the status of the marine ecosystem. For wide areas monitoring a reliable architecture of wireless sensors network is required. In this paper, we present a network of smart sensors, based on ISO/IEC/IEEE 21451 suite of standards, for in situ and in continuous space-time monitoring of […]
Read moreIn this paper, we study the capacity and delay scaling laws of cognitive radio networks (CRN) with static primary nodes (PNs) and mobile secondary nodes (SNs). The primary network consists of randomly distributed primary nodes of density $n$, which have a higher priority to access the spectrum. The secondary network consists of randomly distributed secondary nodes […]
Read moreNetwork on Chip (NoC) has been envisioned as a scalable fabric for many core chips. However, NoCs can consume a considerable share of chip power. Moreover, diverse applications are executed in these multicore, where each application imposes a unique load on the NoC. To realise a NoC which is Energy and Delay efficient, we propose […]
