Essay On Ad Hoc Networking

715 Words3 Pages

Distributed Networking is a distributed computing network system, said to be "distributed" when the computer programming and the data to be worked on are spread out over more than one computer, usually over a network. Prior to low-cost computer power on the desktop, computing was centralized. Although such centers still exist, distribution networking applications and data operate more efficiently over a mix of desktop workstations, local area network servers, regional servers, Web servers, and other servers. A popular trend has been client/server computing which is simply the view that a client computer can provide certain capabilities for a user and request others from other computers that provide services for the clients. A distributed network consists of one or more applications spread over several computers. These computers may be geographically separated from one another. …show more content…

Recent advances in low-power, high-performance processors and medium to high-speed wireless networking have enabled new applications for ad hoc and sensor networks, ranging from large-scale environmental data collection to coordinated battlefront and disaster-relief operations. Ad hoc networking applications differ from traditional applications in three fundamental ways. First, ad hoc networking applications are inherently distributed. Operating on a distributed platform requires mechanisms for remote communication, naming, and migration. Second, ad hoc networks are typically highly dynamic and resource-limited. Liuet. al. [LIU 2005] describes the design and implementation of distributed operating system for ad hoc networks. Proposed system simplifies the programming of ad hoc network and extends total system lifetime by making the entire network appear as a single virtual

‘Chubby’ is a unified lock service created by Google to synchronize client activity with loosely coupled distributed systems. The principle objective of Chubby is to provide reliability and availability where as providing performance and storage capacity are considered to be optional goals. Before Chubby Google was using ad-hoc for elections, Chubby improved the availability of systems and reduced manual assistance at the time of failure. Chubby cells usually consist of chubby files, directories and servers, which are also known as replicas. These replicas to select the master use a consensus protocol.

The aim of SAR algorithm is to reduce average weighted QoS metric throughout network lifetime. Another wireless sensor network QoS routing protocol that ensures soft real-time end- to-end guarantees is SPEED that ensures avoidance of congestion during network congestion. Diff-MAC is a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) based QoS-aware MAC protocol with differentiated services and hybrid prioritization. Diff-MAC aims at increasing the utilization of the channel with effective service differentiation mechanisms while providing fair and fast delivery of the data.

6. Mobility: Almost all of the routing protocols that consider the situation in which the base station, the sensor nodes and the sink are fixed are available. Since, there are some applications available i.e. a clash environment, where mobile is necessary for both sink and sensor nodes. 7. The merger of wireless sensor networks and wired networks required for routing protocols, i.e. the Internet.

• ICMP; is one of the main rules of the internet protocol suite. It is used by system devices, like router, to send error messages showing, for example, that a demanded service is not offered or that a crowd or router could not be touched. • DHCP; Dynamic host configuration protocol is a customer server rules that repeatedly delivers an internet rules (IP) address and other linked arrangement information such as the subnet mask and avoidance entry. • Bluetooth; Bluetooth is a wireless communication technology that lets people to usefully connect their plans with other policies “and “the character of the technology is developing to not only allow devices to talk with one another, but actually allow the all-in-one communication between devices, native requests and the cloud.” •

Goals of the Lab This lab has many different overall goals that are meant to introduce us to the challenges and procedures of building a preliminary enterprise environment from the ground up. Each task has it’s own set of goals that expose us to important areas of system administration in this type of environment. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet. The lab then introduces installation of an enterprise Linux distribution, Red Hat Enterprise Linux 7, which will be used as the main Linux based server in our enterprise environment.

Network internet layer This can be used to set the border line of what people can think of about the network. With this layer it will be able to interconnect with networks and will decide how the layers can do this process. It will be able to can concentrate and determine how the data will get from one remote network to the computer. Also it will take care with devices which are local. This is mainly tasked to take care of is routing which allows data to be moved the data across the series of networks which are connected.

Understanding networking is a fundamental part of configuring complex environments on the internet. This has implications when trying to communicate between servers efficiently, developing secure network policies, and keeping your nodes organized. Every location or device on a network must be addressable. This is simply a term that means that it can be reached by referencing its designation under a predefined system of addresses. In the normal TCP/IP model of network layering, this is handled on a few different layers, but usually, when we refer to an address on a network, we are talking about an IP address.

Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 Andrew LeLusche Professor Gregory Roby Colorado Technical University 1/6/2017 Fundamentals of Networking IT204-1701A-03 Unit 1 Discussion Board 2 In order to choose the correct network for your needs, it is important to first understand the differences, advantages, and disadvantages between a peer to peer network and a client/server network. Whether you are a family home, a mom and pop shop, a data center or large corporation- there is a network for your needs. A network is a system of operating machines that allows a user to access an interface suitable for creating and saving documents, access webpages and video/audio content, run administrative programs to serve clients based on whatever business model or service provider you are. First let’s discuss a peer to peer network.

Sharing Internet Access: within a computer network learners are able to access the internet at once. Speed: Using a network is a faster way for sharing and transferring files. Without a network, files are shared by replicating them to a floppy disk. Cost: Networkable versions of many popular software programmes are available at significant savings compared to buying individual licensed copies. It also allows easier upgrading of the program.
