We all know that during pandemic like corona or generally in hospitals, the front-line workers such as doctors, nurses, compounder in hospitals are nearest to the patients. They all need to look after the patients without caring about themselves and hence doctors, nurses, workers have a high chance of getting contacted to the disease. And few of the medical personnel fearing for the disease and their health, they are not ready to work in the hospital. Hence to tackle this problem we have come up with a solution i.e., Virobot- The artificial nurse. The result of this project is a robot that is designed to act as a medical assistant robot which can be controlled by nurses or doctors from a distance using their smart phone or it can just use autonomous navigation to reach the patients and give them required medicines, monitor patients health and stream all the patient information wirelessly through the internet to your palm(mobile). And, it has built-in UV sterilizer lights, which sterilizes the hospital wherever it travels. Not only it can carry lightweight packages and sterilize the hospital, It can be used as a telecommunication robot ad establish communication between doctor and patient since it is a built-in FPV camera and a Bluetooth speaker. The best thing is all these features are connected to the internet hence the doctor can get data from the robot from anywhere around the world.

This paper proposes a novel approach to emulate an arbitrary wireless multi-hop network scenario in a fixed wireless test-bed, in which every node is equipped with a variable attenuator. We take notice of the interval equivalent character of wireless communication and consider the wireless multi-hop scenario emulation problem as an interval equivalent emulation problem. We define the generalized error, which is an error of a value relative to an interval, formulate the MinGenMax (Minimize Generalized Maximum) error problem and propose an optimum algorithm.

ZBLE: zone based leader selection energy constrained AOMDV routing protocol
Статья научная
In today's life, wireless networks (WNs) are being used very fast in every area. Wireless networks have been used in various applications, but finding some of its weaknesses, such as mobility, diversity, lack of resources and so on, finding an optimum route is very complex and problematic. By reducing the energy consumption on each node, the quality of the network can be ensured. Need to increase the battery life of the node to increase the network lifecycle. Therefore, reducing the energy consumption can extend the battery life of the node. To find and maintain routes between nodes, multi-path routing is a fundamental research issue for such networks. This paper discusses the zone-based routing protocol, which uses the energy, distance and power of the node to maintain high circulation and accelerate the path search process and maintain high search. The Zone-based Leader Selection Routing Protocol (ZBLE) is one of the new protocols, which is a modified form of the famous Ad Hoc on Demand Distance Vector Routing Protocol (AOMDV). Zone Leader Node and Zone Members are selected using the value of energy, position and power of the node. The performance of the proposed communication protocol is evaluated with other existing protocols such as AODV and AOMDV. The simulation result is that when it receives the best path for data communication with proper energy conservation. Network simulator version 2.35 is used for simulation purpose. To support our ideas, we used the 5 quality of service parameters such as packet distribution ratio, energy consumption, network lifetime, and throughput.

ZBLE: zone based leader selection protocol
Статья научная
Various wireless mobile nodes are simultaneously a network that does not depend on any central administration system. This kind of network is called Mobile Ad Hoc Network (MANET). Due to the nodes dependent on the battery in MANET, energy consumption has become a major problem. Because of the mobility of the nodes in the network, the nodes rapidly change their positions, causing the battery to end very quickly, thereby reducing the life of such a network. The main objective of this paper is to reduce energy consumption and increase the life of the network by modifying the AOMDV protocol using zone-based technology. Keeping this objective in mind, a zone-based protocol was developed which has been addressed in the name of Zone Based Leader Selection Protocol (ZBLE). This proposed protocol uses zone-based technology to select the path based on high energy and high power. For the data forward, selecting the Leader node in each zone, the best path is chosen based on the energy level of the node and the strength of the probe. The proposed protocol has been evaluated using Network Simulator version 2.35. Comparison of ZBLE, protocols the most popular protocols are from AODV and AOMDV. With the help of simulation results, we have used service parameters such as packet distribution ratio, energy consumption, network lifetime and throughput to tell the quality of the proposed protocol.
