Vehicular network standard demands a short range reliable vehicle-to-vehicle (V2V) communication with high mobility, also increasing amount of downloaded data in short encounters. Satisfying demands of clients with minimum number of transmissions using index coding has proven notable significance in wireless ad-hoc networks. The proper encoding at the server with side information leads to simultaneous...
For any n-bit boolean function f, we show that the randomized communication complexity of the composed function f o g^n, where g is an index gadget, is characterized by the randomized decision tree complexity of f. In particular, this means that many query complexity separations involving randomized models (e.g., classical vs. quantum) automatically imply analogous separations in communication complexity.
This work is motivated by the need for the fundamental increase of spectral efficiency with the transmissions on the Transmission Control Protocol and the Internet Protocol (TCP/IP). To emphasize the work in physical layer, we define a bit-unit (BU) that is conceptually similar to an IP packet containing sufficient information for its destination node to identify the address and interpret the contents...
In an Intelligent Tutoring System (ITS), the graphical user interface is the main mode of interaction between the program and the user. Thus, it is important to evaluate its usability, which is the system's efficiency and ease of use. For these evaluations, methods such as Nielsen heuristics and questionnaires are more recurrent. However, such procedures cannot detect problems that were not foreseen...
Wireless Sensor Networks (WSNs), deployed in distributed Internet of Things (IoT) applications, measure data, process, exchange information, and function collaboratively with other sensor nodes and end-users, which can be internal or external to the network. To maintain the reliable connectivity and the accessibility of distributed IoT, it is vital to establish secure links for end-to-end communication...
Energy and carbon issue have gained a lot of attention in recent years. However, energy management and services of electric bicycles based on international standards are not very common. This work uses communication standards, including Energybus, MQTT and Bluetooth 4.0 to design an energy management service platform. We implement a system that integrates electric bicycles, smart mobile devices and...
With the increasing of mobile devices, Device-to-Device(D2D) communication is considered as a promising technology for achieving direct communication of devices. But the security issues still remain to be solved. In this paper, We utilize D2D communication between UEs in proximity to share epidemic media contents. We propose a Secure Content Sharing Protocol(SCSP) that combine with the credibility...
In this paper, we consider the privacy preserving problem in an agreement network under interception attacks. First, we introduce a consensus protocol with privacy preserving, where each node hides their initial states into a set of random sequences, and then injects the sequences into the process of consensus. Second, we assume that an attacker with limited power can intercept the data transmitted...
In this paper, we investigate the consensus problem for the second-order multi-agent systems with communication time-delay. We firstly introduce the consensus protocol based on neighbor directed network. Then by using Lyapunov functions, we prove the stability of the proposed control protocols, and derive a sufficient condition for the consensus convergence of the multi-agent system. Finally, simulation...
This work is motivated by the need for the fundamental increase of spectral efficiency with the transmissions on the Transmission Control Protocol and the Internet Protocol (TCP/IP). We define a bit-unit (BU) that is conceptually similar to an IP packet that contains sufficient information for its destination to identify the address and interpret the contents. Armed with these functions, each BU is...
This paper aims at carrying out a parameters sensitivity analysis on a charge transport model using an approach based on the Sobol's method when data at different temperatures, different applied electric fields and different charging times are available. The Sobol's approach applied herein is used to study how the variation of the current density and charges density can be quantitatively apportioned...
Wireless Sensor Network has constraint with energy and computation. Network Life is based on the way the energy in the battery is used. Continuously sending data along a specific path for long intervals of time, results in large amount of energy consumption. This could eventually lead to network partitioning, which in turn will create a path loss between the sender and receiver. Though several (sensor)...
With the widespread use of embedded software, the embedded software testing has become an indispensable part of the development process. The current representative tools for testing embedded software include ADS2 made by TechSAT, RT-LAB developed by OpalRT, and GESTE developed by Beihang University. However, their degree of automation is inadequate. Therefore, this paper studies an automatic testing...
Internet of things(IoT) is the system which interrelates different computational devices, digital machines, mechanical machines and they have been bestowed with unique identifier having the talent to send data over a interconnection of networks which does not require interactions between human and human or machine and mankind. In this manuscript we have discussed about the different communication...
In this paper, a novel two-phase orthogonal frequency division multiplexing-index modulation (OFDM-IM)-aided cooperative relaying protocol is proposed for overlay cognitive radio (CR) networks, where the primary and secondary networks work concurrently over the same spectrum band. In the proposed scheme, OFDM-IM technique is used at the secondary user (SU) to split the transmission space into the...
In this paper, we consider the consensus tracking for second-order multi-agent systems via adaptive repetitive learning control. Under the assumption that the velocity information may be unmeasured for any of the following agents, an observer-based distributed adaptive repetitive learning consensus protocol is designed. Based-on the Lyapunov stability theory, a sufficient condition which guarantees...
Ongoing emphasis on the fourth industrial revolution requires further focus on the Internet of Things (IoT) as a means to integrate all relevant entities within a single technological system. In the integration process, a gateway to relay the raw data to an IoT endpoint is essential so that a joint interface among the heterogeneous domains can be provided. This work describes the development of a...
In order to achieve network interface plug and play (PnP) of IEEE 1451 networked smart sensor, this paper presents network interface's universal plug and play (UPnP) mechanism of IEEE 1451 networked smart sensor. Firstly, UPnP based IEEE 1451 networked smart sensor system structure is set up. The self-recognition information conversion between IEEE 1451 model and UPnP model are elaborated. Scheduling...
Industrial Internet of Things covers all aspects of networked intelligent manufacturing systems. This means covering a wide array of application domains and user requirements. In such scenarios it is not feasible to define a single protocol for all situations. Hence, a multi-protocol approach is required. OPC UA has strong backing from Industry 4.0 as the protocol for the Industrial Internet of Things...
Local distinguishability of quantum states is a basic problem in quantum information theory. For an arbitrary group of entangled states in d ⊗ d bipartite system, Singal presented a subspace related to these states, and then he determined that the group of states can be distinguished by one-way local operations and classical communication(1-LOCC) if this subspace contains a maximally Abelian subspace...
