With the growing demand for quality-of-service (QoS) aware routing protocol in wireless networks, QoS-based routing has emerged as an interesting research topic. Quality of service guarantee in wireless sensor networks (WSNs) is difficult and more challenging due to the fact that the available resources of sensors and the various applications running over these networks have different constraints in their nature and requirements. In this paper, we present a heuristic neighbor selection mechanism in WSNs that uses the geographic routing mechanism combined with the QoS requirements to provide multiobjective QoS routing (MQoSR) for different application requirements. The problem of providing QoS routing is formulated as link, and path-based metrics. The link-based metrics are partitioned in terms of reliability, delay, distance to sink, and energy, and the path-based metrics are presented in terms of end-to-end delay, reliability of data transmission, and network lifetime. The simulation results demonstrate that MQoSR protocol is able to achieve the delay requirements, and due to optimum path selection process, the achieved data delivery ratio is always above the required one. MQoSR protocol outperforms the existing model in the literature remarkably in terms of reliable data transmission, time data delivery, and routing overhead and underlines the importance of energy-efficient solution to enhance network lifetime.

The main purpose of this paper is to assess the system reliability of electronic transaction data transmissions made by commercial banks in terms of stochastic flow network. System reliability is defined as the probability of demand satisfaction and it can be used to measure quality of service. In this paper, we study the system reliability of data transmission from the headquarters of a commercial bank to its multiple branches. The network structure of the bank and the probability of successful data transmission are obtained through the collection of real data. The system reliability, calculated using the minimal path method and the recursive sum of disjoint products algorithm, provides banking managers with a view to comprehend the current state of the entire system. Besides, the system reliability can be used not only as a measurement of quality of service, but also an improvement reference of the system by adopting sensitivity analysis.

This research addressed the issue of improving the quality of service for the control system of mobile radio networks. The analysis of the forecasting sphere concerning the methods of service quality of mobile radio networks for special purposes, in particular, forecasting the time of congestion of data transmission routes is carried out. It is found that these methods are used in wired and computer networks operating at the network and data link levels. The basic parameters of the protocols of the channel and network layers of mobile radio networks are highlighted. Forecasting methods are analyzed: temporal extrapolation, causality, expert, and the main disadvantages are indicated. A model of a control system for mobile radio networks with a forecasting subsystem is shown. The features of mobile radio networks, which form the requirements for routing methods, are described. A lot of requirements have been put forward for the model of a control system for mobile radio networks. The structure of a model of a control system for mobile radio networks with an improved forecasting subsystem is proposed. On the basis of genetic algorithms, the tasks that arise in the process of identification, training and forecasting in the forecasting subsystem are solved. The operation of the processes consists in building a base of rules aimed at identifying significant dependencies in a time series based on the use of a genetic algorithm. It is based on the use of evolutionary principles to find the optimal solution. Application of the proposed model will allow real-time identification and will significantly improve the quality of service for mobile radio networks. It will increase the speed and volume of data processed during training, improve the quality and reliability of predicting changes in data transmission routes

Banks as service providers have to behold to the security of ATM in various regions since CCTV and the existing security officers unable to overcome the problem of ATM damage or burglary maximally. ATM crime monitoring system was created to solve this problem by sending alarms and notifications in real time. The main focus of this paper is to define the data transmission on ATM crime monitoring system using MQTT. MQTT is used on the system as a protocol for sending data from the Arduino Mega 2560 microcontroller and SIM800L devices to the server. All data from various sensor will be sent in JSON format and Quality of Service (QoS) used in MQTT is level 0. Data transmission using MQTT may filter normal conditions and alert conditions on ATM, data sent using 2 topics in order that the data can be used to send notifications and alarms in real time. In this research, SIM800L circuit configuration, SIM800L programming and MQTT protocol on Arduino IDE, and data transmission testing were carried out. The results of the research are that data transmission is successfully sent in real time and the filtered data is successfully divided into 2 conditions, namely under normal conditions and alert conditions. Further development can be done by replacing QoS with level 1 for the security of the data.

Wireless ad hoc networks are increased with respect to data transmission between different nodes via relay routing in real time network environment. Wireless ad hoc networks are the collection of different wireless nodes which communicate over common wireless medium. Relay configuration of particular node over relay routing is a complex task which improves the quality of service parameters based on basic standards in routing communication scenarios. Different security challenges appear in this scenario because of misbehaving nature of intermediate nodes in data transmission with respect to scalability and efficiency in wireless ad hoc network communication. So that in this paper we present and develop a Hybrid approach, which consists unital key distribution approach and dynamic source optimized routing scenario to improve scalability and efficiency for key sharing to all the nodes in wireless networks. Performance of proposed approach in terms of increasing quality of service (QOS) parameters in wireless ad hoc networks.

Multimedia file transmission with quality of service is the important issue in Mobile Ad-hoc Networks. The real-time data is in the form of audio file and the video file. These kinds of files can be divided into several data packets and the data packet is delivered from the begining node to the recipient node within the limited amount of time. The increase of throughput is possible only by means of secure data transmission. So, the secure data transmission methodology is used to implement the quality delivery of the multimedia files. The sequence of data packets are encoded and decoded using the encryption and the decryption process. The simulation results proved that the proposed method has the highest amount of throughput, delivery ratio and also improving the quality of service compared to all the other related methods.

Qos Requirement

This paper discusses a group communication protocol to exchange multimedia messages in a group of multiple peer processes. Quality of Service (QoS) required by an application has to be supported. In traditional protocols like RTP, a process can reliably deliver messages to one or more than one process. In the group communication, each process sends a message to multiple processes while receiving messages from multiple processes in a group. Due to the limited computation and communication capacity, we cannot adopt traditional one-to-one or one-to-many transmission ways to the group communication. We propose a notification-based data transmission procedure to exchange multimedia messages among multiple processes so as to satisfy QoS requirement.
