Application Of Using An Application For A Communication Network

Bandwidth: Is the bits per second that a link is capable of transmitting (ie: Exetel currently advertise their ADSL2+ connections to be up to 20,000/800kbps Download/Upload bandwidth)

Wireless network infrastructure has become just another connection method for corporate and home users alike. This rapid acceptance can be attributed from:

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

It is a metric in the network; also, it’s not free, because it cost money when you use it in either analog or digital from determine the overall bandwidth of a system, including the specific devices, the type of data sent, the network topology, the amount of users, and so forth. In my opinion, I prefer digital bandwidth, because it’s fast, so it’s multiple ways to reach the end like you get the result fast.

In today’s society, it is commonplace for one to be electronically “connected”, by using devices like computers, mobile smartphones, gaming devices, tablets or laptops. Typically there is some type of network, which enables us to be connected, such as a Wide Area Network (WAN), a Local Area Network (LAN) or even a Home Area Network (HAN). A WAN is the most expansive type of network commonly used, which can cover large geographical areas, usually by amalgamating multiple LANs. The most frequently used WAN is the internet, which many of us connect to daily. A smaller type of network is a LAN, most often used in the workplace to connect computers and devices in the same office or building, so users can collaborate and efficiently share resources.

In this smart world there is a rapid growth in using mobile network for requesting many queries, especially videos.Problem is more Base Staion (BS) is required for providing a continuous service, for the user to view videos without getting buffer, or in degrading of video quality. Since more BS are required, all BS has to be active all time, therefore energy requirement is more. It cause more power consumption, also if BS is reduced for save power it leads to poor quality of service(QOS). During peak traffic load during rush hours, wireless access network must be over deployed. It requires lot of BS to be active even when many times slots in a BS are free while providing service. Also, in a low-traffic period, the user will not request any data, but the BS have to be active.

The functional requirements of the BS is a data communication with Tier 1 devices, sufficient computing power, and \ac{WAN} accessibility. In most of the research, however, a single computing device with a network tool for the Internet or combined device configuration, such as a PC with a gateway or wireless router, and smart phone, has used as Tier 2 system due to its simplicity and effectiveness \cite{leijdekkers2008self, jin2009hearttogo, monton2008body, pandian2008smart}. The modern wearable and mobile devices, such as a smart watches and smart phones, can be employed as a \ac{cDAQ} in Tier 1 due to it has enough computing power and storage capacity to handle the data, as well as a \ac{BS} of Tier 2 when they support the Internet connection

It’s very important to determine the device and application requirements based on bandwidth, protocols and frequency. In wireless network, bandwidth, protocols and sometime environmental conditions affect the speed of the channel so we need to calculate the aggregate throughputs before designing the network. Today, users carry Wi-Fi devices such as notebooks, laptops, tablets and Smartphone’s so total throughput must be calculated by estimating number of connections rather than the number of the seats. Some common wireless networking standards such as 802.11a/b/g/n invented in the IEEE association must be supported by wireless network. For better performance and for faster devices (802.11n devices), dual-ratio access points should be deployed. Table1 [3] illustrate the different IEEE standards and throughput.

Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure, a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow, released in the year 2008, is a commercially viable implementation of this concept that is being well received by the networking industry at large. The paper also discusses the OpenFlow protocol, its implementation and the challenges facing its widespread acceptance

One proposed method for mitigating the address shortage problem in IPv4 is to use network address translators (NATs) to allow address reuse. The [3] basic idea is to transparently map a wide set of private network addresses and corresponding TCP/UDP ports to a small set of globally unique public network addresses and ports. NAT is a technology which is implemented, deployed and configured as a feature on devices like routers, servers, firewalls etc. When NAT is deployed and configured on the devices, it would make it possible for LAN devices with private IP addresses to communicate with the devices on the public network. NAT would typically be deployed and configured on equipments like routers, firewalls which have already access to the public network. The traffic which is initiated from the private network

Thus, a mobile station able to operate on several technologies should roam freely from one interface to another, being able to maintain its network connection and the QoS required by higher layer applications. The vertical handover is a very important capability in the future wireless communication era, where an integrated network grouping multiple technologies will try to offer a global broadband access to mobile users. However, compared to the horizontal handover, the signal strength metric is sometimes not suited and often not sufficient to appropriately trigger the vertical handover: as heterogeneous networks have different system characteristics, their performance cannot be simply compared using the signal strength of two cells [12]. At a particular position, there may be more than one network (WLAN, WCDMA and Wi-Max) available. On the other hand it may happen that the desired network, through which the vehicle is communicating currently, is not available at a particular area. Thus it is required to change the network immediately to ensure QoS. Vertical handoff enables seamless terminal, personal and network mobility. It provides for continuity and transfer of existing sessions. Vertical handoff can be separated into three phases: network discovery, handoff decision, and handoff execution [8]. This paper aims at defining an efficient user-driven vertical handover mechanism which does not require any change on network and Protocol

Advancements in the information technology sector have brought many benefits to the people all around the world.  Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.

(AP)-based mechanism. Mobile networks, Wi-Fi hotspots requires user devices to connect to a common base station before they can operate. Use of Device to Device (D2D) connectivity is so beneficial and is at the forefront of standardisation and research efforts. Some commonly scenarios for D2D are Internet of Things mechanism, machine to- machine communication, device replacement (in case of failure), social data sharing. Device¬-to-Device has the potentiality to play a vital role in future LTE offloading strategies. However, many of the promises in store for D2D commu¬nication lay bare what is arguably its biggest flaw: no "static" infrastructure, the availability of content is spotty and unreliable. Even if requested content is cached by a nearby node, reachable through a multi-hop D2D path, a robust content discovery and retrieval mechanism is needed. In this paper, we focus on the potentiality of Wi-Fi Direct as D2D communication technology in medium and large-scale scenarios, using open-source, non-rooted Android devices. [3] – [5].

Energy efficiency: Wireless/mobile broadband infrastructures account for more than 50% of the energy consumption of telecommunication operator networks, while the amount of global energy consumption of ICT approaches 4.5% with a rising trend4. It is important that future 5G networks meet requirements
