Channel estimation plays an important role in the performance of any communication system. To reduce the effects of hostile channel signals, precise channel estimate must be performed during signal processing. To achieve higher array gains for the signal as well as to reduce hardware cost hybrid precoders are used. It is difficult to configure hybrid precoders and combiners in Multi-User Multiple Input Multiple Output(MIMO) antenna systems that are operating at mm-wave frequency band. In this paper, a modified simultaneous weighted orthogonal matching pursuit technique is proposed for channel estimation in Massive MIMO systems, both on the uplink to configure precoders and on the downstream to configure combiners. In this first, the base station estimates the mobile station's channels on each sub-carrier and estimates the mobile station's channels. Then, the mobile station channel estimates the hybrid precoders and combiners of the designed base station. In this paper, the performance of channel estimation is measured in terms of normalized mean square error (NMSE) and spectral efficiency (SE). From the simulation results, it is observed that the proposed algorithm reduces the NMSE and improves the SE as the number of users in the massive MIMO antenna system increases.

In this work, we had proposed a smart irrigation system using Cisco packet tracer software for Indian climatic conditions. We had used different sensors, webcams, and different electronic devices for smart control and security of the farms. Different analyses for different crops (Kharif and Rabi) are discussed so that effective use of water and resources are maintained. For each case, proper simulation is done on the software. In the later section, security-based simulations are done and discussed. With the help of the Internet, our farmers can control and monitor the farms staying away from it.

In Mobile Adhoc Networks (MANETs), resilient optimization is based on the least energy utilization as well as privacy. The crucial concerns for the productive design to provide multi-hop routing are security and energy consumption. Concerning these problems, we present in this paper an author proposed routing protocol called Protected Quality of Service (QoS) aware Energy Efficient Routing protocol. It is developed on trust along with energy efficiency and points to improve MANET security. The proposed work utilizes an identification methodology in the company of a key based safety feature for assigning trust ratings. This study also determines three categories of trust ratings, including direct, indirect, and overall trust scores, beneficial to increase communication security. The head of a cluster is selected among the nodes based on QoS metrics and scores of the trust which is referred to as a cluster based secured routing approach. Finally, to carry out the safe routing procedure as efficiently as possible, the required final path that is picked depends on path trust, energy consumption, and hop number. The suggested work was evaluated via simulations using the Ns2 simulator. The proposed strategy beats others in the matter of enhanced delivery rate of the packets, lifetime of a network, and security according to the simulation findings. Further, the proposed safe routing technique saves time and energy as compared to current relevant secure routing methods.

Artificial neural networks are known for their superior performance in many applications. Weights obtained during training are fine-tuned to the training data used. As a result the performance is reduced when tested with unseen data. Also, the use of backpropagation algorithms used in conventional neural networks is time consuming. Extreme learning machine classifiers are known for better generalization and quicker training compared to the neural networks with back propagation. In this work, the performance of the above mentioned classifiers on both seen and unseen data when used with cepstral coefficients is compared.

Vehicular Ad-hoc Networks (VANET) are capable of offering inter and intra-vehicle wireless communication among mobility aware computing systems. Nodes are linked by applying concepts of mobile ad hoc networks. VANET uses cases empower vehicles to link to the network to aggregate and process messages in real-time. The proposed paper addresses a security vulnerability known as Sybil attack, in which numerous fake nodes broadcast false data to the neighboring nodes. In VANET, mobile nodes continuously change their network topology and exchange location sensor-generated data in real time. The basis of the presented technique is source testing that permits the scalable identification of Sybil nodes, without necessitating any pre-configuration, which was conceptualized from a comparative analysis of preceding research in the literature.

An increasing number of natural and artificially induced disasters shows the need for rapid disaster management methods backed by a reliable communication infrastructure and data source. Disasters bring losses to human life, livestock, properties and habitat. Building collapse is one of the disasters that predominantly endanger the local population. A proper rapid disaster management mechanism can cut down postdisaster damages. During a disaster, natural or otherwise, the Internet of Things (IoT) can play a crucial, potentially life-saving role. IoT systems support disaster management operations such as prevention, preparation, response and recovery phases. This paper summarises the existing IoT systems designed for disaster management and rescue operations. This paper proposes a fog computing and UAV-based IoT network architecture to combat the problems associated with frequent disasters focusing on collapsed buildings. The proposed architecture assists rescuers by integrating IoT sensors and UAVs data with the status of infrastructures. The architecture supports the rescuers by providing real-time data by analyzing disasters and facilitating disaster search and rescue operations. The paper also proposes a communication system with Lora mesh to transmit critical information to the base station during post-disaster situations. It presents the results from a prototype implementation of the proposed architecture in the Google Cloud Platform.

This work proposes a four-port MIMO square patch antenna for 5G Internet of Things (IOT) applications. A Spilt Ring Resonator (SRR) is etched on the ground construction to boost the antenna's performance. The antenna's bandwidth is increased as a result of SRR. The proposed MIMO antenna has a 60*60 mm dimension at 24GHz radio Frequencies. The antenna is mounted on a 1.6 mm thick FR4 substrate. The developed antenna has a broadband function at 24–30 GHz, which is suitable for 5G applications, as per the ANSYS simulated results in this proposed work. Antenna properties such as reflection coefficients Snn −10dB, transmission coefficients Snm −20dB, gain, axial ratio, and radiation pattern are all simulated. Furthermore, for the full range frequency, the Envelope Correlation coefficients (ECC) for the proposed four port MIMO antenna design are less than 0.015. From the mathematical analysis and simulation results, the proposed MIMO antenna is better selection for 5G application with improvement is optimal stability transmission.

This work involves the designing of a calculator which performs basic operations such as addition, subtraction, multiplication, division, factorial, square root, square, and cube. This is implemented using the MIPS32 (Microprocessor without Interlocked Pipelined Stages) processor, which has a five-stage pipelined architecture and 32 registers, using Verilog HDL in the ModelSim software. An interface module is created in which the processor module is instantiated to provide the two-phase clock input and control signals to the processor and for the user to inputs. Based on the choice of operation and the operands provided, the corresponding operation would be executed and the result would be displayed. The assembly language code for each operation is coded as 32-bit instructions within the interface module and stored in the memory. The processor fetches, decodes, and executes these instructions and stores the result in one of the registers, which is then displayed to the user using the interface.

The core challenge in wireless sensor networks is to design an efficient data gathering algorithm that improves the energy efficiency and lifetime of the node without delay. Data gathering is a process of collecting the sensed readings at predefined points to perform the analysis to process it. In a static-based approach, the collected data is flooded through the network and the node near to base station is highly affected resulting in non-uniform energy consumption, becoming vulnerable to hotspots or energy hole problems. As the static sink is inadequate and inefficient in energy utilization causing network performance degradation and shortening of network lifetime, the sink mobility concept is put forward to mitigate the energy hole issues among the nodes. Finding and selecting the optimal mobility trajectory of the mobile sink to gather the data efficiently become a challenging issue in sensor networks. Bio-inspired and machine learning based mobile sink path determination recently proves to be an effective method of data collection. This paper reviews different mobile sink data aggregation and path determination approaches to select the appropriate method for various applications.

In this study, we examine the performance of a dual-hop assisted amplify-and-forward (AF) based high altitude platform station (HAPS) free space optical (FSO) communication system. The HAPS used in the considered system act as an AF relay to provide connectivity between the two terrestrial stations. FSO links characterized by Gamma-Gamma atmospheric turbulence, pointing errors, and angle-of-arrival (AoA), provide connectivity between ground stations and HAPS. Closed-form expression for the outage probability (OP) and bit-error-rate (BER) of the considered AF relayed dual hop HAPS-FSO system are derived in this work. The numerical results reveal that the system's OP and BER are influenced by atmospheric turbulence, beam width, angle of deviation of the HAPS along with the different modulation techniques.
