1.0 INTRODUCTION For mini project of this subject, I choose to analyze performance management of different Wi-Fi based on context Wi-Fi service provided in my house area which is SriPuteri WifiNet. To analyze the performance management, I have to identify the problem statement, scope and method to use. In Local Area Network (LAN), although multiple device such as PC, laptop, mobile phone and many more can connected to Wi-Fi but as the increasing of device used, the network can become slower because of data traffic congestion. To overcome the problem, it is essential to have a good Network Management plans. In Network Management, there are three main aspects that must considered which is Security, Performance and Reliability. Security is on how to ensuring the network protected from unauthorized users, Performance is on how to eliminating bottleneck in the network and Reliability is to make sure the network is available to users and responding to hardware and software malfunctions. Based on my mini project requirement, I have to analyze the network based on Performance Management. Performance Management is derived on monitor end-to-end performance including monitor component performance (throughput), how the react of respond time when we sent a request to network, and how the traffic flow in network. 2.0 PROBLEM STATEMENT There are several problems that affect the efficiency network performance:- 2.1 Performance Performance can be measured by the consumption of bandwidth and the flow of the traffic, throughput, data latency or delay time, packet loss and retransmission of data. Throughput is the amount of traffic a network can carry at any one time, the higher the bit rate, the faster files transfer. If there is a lack ... ... middle of paper ... ...problem such as bottleneck, traffic overload, retransmission. 5.0 METHODS To measure a performance management on Wi-Fi, I used Wireshark as a medium to tracking all network activity. Wireshark is a packet analyzer software to see visible traffic on network. It also captures data packets in real time and displays them in human-readable format. Figure 1 : WireShark interface 6.0 CONCLUSION As a conclusion, the performance management of network management are one of essential things of aspect in networking. The efficiency performance of different wifi are based on two aspects, performance and hardware. To make sure a good network performance, we must monitor all of the network activity and analyze all the data including network traffic, bandwidth, latency and etc. From the input, we can use this information to troubleshoot if there is an error in network.

You have probably taken advantage of Wi-Fi access when traveling, at airports, in your hotel room, shopping, enjoying a latte at your favorite coffee shop or even waiting for your doctor to see you. In today’s world, Wi-Fi is an important feature whether you are in the hospitality industry, (free, high speed, in-room Internet access ranks as the most desired guest-room amenity), at an event (free Wi-Fi affects the choice of venue ), or in an office/hotel lobby, bar, restaurant or conference room. As a business owner or IT manager selecting the right wireless solution can have either an adverse effect on business or be a highly beneficial
Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas they cover. Ethernet has dominated the LAN side, while ATM covers the WAN (backbone). This paper will compare the two technologies and determine which has a hand-up in the data trafficking world.
‘If you can’t measure it, you can’t management it’, [Dan vesset and Brian, M. 2009]. Performance management is concerned with the measurement of results and with studying progress to achieving objectives base on the results. Managing performance can tell you what you’re doing well in, and also reveal areas where you need to make adjustments. Measuring performance tells you how far you’ve gone achieving your ultimate

Wi-Fi facilitates ease of use and is getting increasingly popular with homes and businesses. Multiple Wi-Fi Access Points can be located in a given area. Wi-Fi security issues continue to be a problem, as the number of Access Points grows.
Performance Management - is an ongoing communication process, undertaken in partnership between an employee and his or her immediate supervisor. Done together, this approach involves establishing clear, shared expectations and understanding about:
Performance management is a management tool used to value, monitor and measure a company’s strategies that ensure the efficiency and effectiveness of its product delivery. This management tool does not focus on the organisation and on its employees as well as stakeholders. It is a continuous process that entails that managers make sure that organisational and employee values are corresponding (Aguinis, 2005,p.1/2-1/5). Performance Management brings about the competencies in the employees, increases self-esteem by giving feedback to employees, there is a low number of lawsuits because it helps understand the company better (eThekwini Municipality, 2008,p.10-11). According to Pride, Hughes and Kapoor (2011, p.288) performance management creates motivation for employees; one theory of motivation is of Expectancy, which stipulates that employees satisfaction is driven by expectations of what an organisation will offer in return.
Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing Internet wirelessly at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly by a router. By transmitting signals at 2.4 or 5 GHz it allows the waves to transmit more data at a faster rate. Typical Wi-Fi standards are 802.11a, b, g, n, or ac and they can switch up the frequency depending on the model (Brain). Families can create their own wireless network that can be shared between family members without the use of hooking all their devices up to the modem and can also protect their home network from potential hackers with the use of a TKIP or AES encryption. Businesses can also create a “hotspot” which is an area that has wireless networks for free or at a set fee. This is extremely convenient for commuters that need internet access while they are at work, waiting on a plane, or just sitting at a coffee spot without the need for wires(Cox).
This paper describes the basic threats to the network security and the basic issues of interest for designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers

Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
Computers in technological development demand more efficient networking. In a very short period it has changed the way we have looked at things since centuries. It is one industry that is going to shape our future for centuries to come Coming from a background of Electronics and Communication Engineering, I have developed an interest to probe into the area of Networking and Computer Networks. Hence I wish to do Masters in Computer Science (CS) as my major.
Performance management is a useful and powerful tool that can be used by managers to identify what areas of their organisation they need to improve to increase the organisation’s overall performance. The idea of a balanced scorecard enforces a sensible distribution of resources and effort across all aspect of performance an organisation is, or should be, concerned with.
Short for Simple Network Management Protocol, a set of protocols for managing complex networks. The first versions of SNMP were developed in the early 80s. SNMP works by sending messages, called protocol data units (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP requesters.
