The Variation Of Link Quality Of Wireless Channels Essay

Figure 8.3(a) demonstrates a portion of a wireless ad hoc network where a source node S has a data packet to be sent to a destination node that is

Geographic Adaptive Fidelity (GAF): Geographic Adaptive Fidelity is an energy-aware location based routing algorithm planned for mobile ad-hoc networks but has been used to WSNs. Geographic Adaptive Fidelity conserving energy by switching off redundant sensors nodes. In this routing protocol, the entire network is classified into number of static zones and a virtual grid is made for the covered region. Every node utilizes its GPS-indicated location to link itself with a point in the virtual grid. Nodes linked to the same point on the grid are assumed equivalent with respect to packet routing costs. Nodes within a zone cooperate by choosing one node to show the zone for a period of time whereas the rest of the nodes sleep. A sample situation is considered from

We have simulated another network having 30 numbers of nodes. The simulation is made using the same platform used for network 1. This simulation is done taking node 1 as a source and node 28 as destination. The optimal path obtained in this simulation is 1-23-13-28, in which data rate is 0.47 kbps. The second optimal path is 1-17-28, in which data rate is 0.35 kbps. The simulated results are summarized here in

A group of wireless sensor nodes (devices) dynamically constructs a temporary network without the exercise of any pre-existing network infrastructure or centralized administration. The main goal of ad-hoc networking is multihop broadcasting in which packets are transferred from source node to destination node through the intermediate nodes (hops). The main function of multi hop WSN is to enable communication between two terminal devices through a bit of middle nodes, which are transferring information from one level to another level. On the foundation of network connectivity, it dynamically gets to determine that which nodes should get included in routing, each node involved in routing transmit the data to further

Currently billions of mobile devices are connected to wireless networks and by the year 2020 when the massive arrival of 5G to the market is expected to be four times higher. This paper aims to analyze the advances in communication for these networks that will be present in all types of portable devices and personal use in addition to computers. It evaluates the progress for aspects of communication and ability to transfer data and information through new wireless networks. The benefits and improvements in communication and performance in different devices for 5G networks are evaluated; this 5G of wireless networks promises an excellent performance in the exchange of personal, business and institutional data, also this paper

Unfortunately, it is a big overhead to maintain routing tables in the mobile ad hoc network

The Mobile ad hoc networks is one of the emerging technologies today. The instability of the nodes in a mobile ad hoc network makes it difficult to calculate the reliability of the network. When a node moves freely move in a

MANETs (Mobile ad-hoc network) is defined as autonomous collection of wireless mobile nodes that are self-configure to construct a network that can communicate over relatively bandwidth constrained wireless links.

Wireless is the term used to describe any computer network where there is no physical wired connection between sender and receiver, but rather the network is connected by radio waves and or microwaves to maintain communications (Boyds, 2016). Wireless and mobile technologies continue to have a major impact on the global business environment and can be roughly categorized into mobile client devices for interactivity and communications infrastructure. Wireless technology is technology that uses radio waves to transmit and receive data, such as cell phones. It is used more than ever today for data transmission. Mobile

A wireless network is any type of computer network that uses wireless data connections for connecting network nodes .Wireless networking is a method by which homes, telecommunications networks and enterprise (business).Installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model  network structure.

Audience for this topic can be the anyone who has some basic knowledge about networking. This Document provide detailed information about quality of structure (QoS) in wireless networks and cellular networks.

Ad hoc networks consist of a set of self-organized of mobile nodes which cooperate using a routing protocol to facilitate the communication. They have become very popular in recent years due to their characteristics: easy deployment, lack of infrastructure, dynamic topology, mobility and minimum commissioning costs.

In this global world of technologies where the communication is being modern day by day, on every other day the new technologies are being invented so in this vast world of growing technologies the cognitive radio network is another addition and a step toward fast and secure communication. Cognitive radio network is the network used for wireless communication which uses the spectrum of frequencies. It is an intelligent network in a sense that it can recognize the channels in use or vacant, the ability of this network is that it can shift the data on vacant channel without letting the other busy channel get disturbed. CRN is a technology which works on the spectrum of frequencies, sensing the spectrum of frequencies at receiver’s
