Abstract

Cooperative communication systems, which make use of the intermediate relays between the transmitter and the receiver, have been employed as an effective technique to combat the channel fading and to enhance system performance. Cooperative systems have some drawbacks such as high latency and may diversity order not guaranteed. To alleviate the negative effects of these factors, the relay selection protocol is employed in cooperative communication systems to increase overall cooperative system performance. Relay selection in the cooperative systems enables the source to cooperate with the single relay node rather than multiple relay nodes which guaranteed the diversity order.

Abstract

Among the crucial invention of the 5G is the device to device (D2D) system, whereby cellular gadgets correspond via immediate transfer or by multihop transfer excluding the ground-terminal. It is probable that D2D users are concurrent with human body network. Due to this, we suggested an internet of health things (IoHT) system which enables collaboration work among D2D users and human body indicators. We may regard the power as the most unique source in the wireless body area network (WBAN). The least needed transferring capacity may accomplish a particular degree of function, and minimum capacity for transfer holds a crucial responsibility in decreasing power usage. In this study, we discovered the needed transfer energy of four transferring modes: the straight transferring system, the double-hop transferring system, as well as double increasing coordinated transferring system with Rayleigh medium vanishing in its layout. Besides that, we suggested an energy-competent system named as efficient-power transmission mode selection-based (EPTMS) system. The suggested system chooses suitable transferring system whereby it offers the least needed transferring energy that assures a particular transfer duration. The statistical as well as simulation results shows that the two-master node cooperative protocols (TMNCP), EPTMS may enhance system conduction within the main criteria.

Abstract

In the recent health-care field, the interent of health thigs (IoHT) technologies provide appropriateness between doctors and people receiving medical treatment, because they are useful to several curative domains. The wireless body sensors networks which can be abbrivated as every technology of a WBSN is an important one from IoT growing’s of the health-care model, as all sick people are observed utilizing some set of nodes of sensors that are light as well as with no high power. In this paper, we proposed energy harvesting-based inter-WBSN cooperation network coding (EH-IWCNC) for Internet of Medical Things.

Abstract

A WBAN can be spread over a person's body, so; posing, dressing, moving of muscles, degree of heat of bodies as well as weather changes in general affect connections among sensors as well as desired point. Secondly, information collected via every sensor can be connected to a person's course of life; so, it can be considered as significant to guarantee that the collected information ought to be given to desired point competently. In this work, a critical cooperating communicating protocol to WBAN established on information has been suggested, called critical data transmission using transmission mode selection (CD-TMS) method established for the architecture of star topology. In the beginning, we performed a studying, also we established a system model can be looked at according to channel los of path, effective transmitting possibility, as well as the out of work time possibility. Thirdly, relaying selecting can be used accompanied by CD-TMS, that lets just the most successful relaying take part in cooperating in a spread manner. Simulating as well as numeral outcomes illustrate that CD-TMS has the ability to develop the performing of a network under common terms comparing with direct transmission mode (DTM) IEEE 802.15.6 CSMA as well as benchmark.

Abstract

In this paper, we report new nanoscale plasmonic multiple inputs logic gates based on insulator-metal-insulator (IMI) nanoring waveguides. The proposed all-optical gates are numerically analyzed by the finite element method. NOT, AND, NAND, NOR, and EX-NOR all-optical logic gates were suitably designed and investigated based on the linear interface between the propagated waves through the waveguides. The operation wavelength was 1550 nm. The simulation results show that the optical transmission threshold of (0.26) which performs the operation of planned logic gates is accomplished. Moreover, simulation results show that our compact structure of all-optical logic gates may have potential applications in all-optical integrated networks.

Abstract

The rise of wing-rock motion in delta-wing aircraft has an adverse effect on the manoeuvrability of aircraft and it may result in its crash. This study presents a finite-time control design to tackle the dynamic motion due to the Wing-Rock effect in delta-wing aircraft. The control design is developed based on the methodology of Super Twisting Sliding Mode Control (STSMC). The Lyapunov stability analysis has been pursued to ensure asymptotic convergence of errors and to determine the finite time. The design of STSMC leads to the appearance of design parameters, which have a direct impact on the dynamic performance of the controlled system. To avoid the conventional tuning of these parameters and to have an optimal performance of the proposed controller, a modern optimization technique has been proposed based on Wale Optimization Algorithm. A comparison study between optimal and non-optimal finite-time super twisting sliding mode controllers has been established and their effectiveness has been verified via numerical simulation using MATLAB programming format.

Abstract

The surveillance and security of areas such as home, laboratory, office, factory, and airports, are important to prevent any threatening to human lives. Mobile robots are proven their effectiveness in a large number of applications, especially in hazardous areas where they can be remotely controlled by humans to accomplish certain tasks. This research paper presents a design and implementation of a mobile robot for surveillance and security applications. The main objective of the design is to lower the cost and the power consumption of the mobile robot which accomplish using low-cost open-source hardware such as Arduino and Raspberry Pi. The robot is connected wirelessly via a low-power ZigBee module to the control station to allow the operator for controlling the mobile robot motions and monitoring the physical events in the environment where the robot is used.  Sensors such as camera, temperature, and range are embedded in the robot to sense and monitor human motion, the room temperature, and the distance of the surrounding obstacles. The testing of the implemented mobile robot shows that it can run continuously for approximately 6.5 hours at a motor shaft speed 25 rpm of unlit the need to recharge the battery.
