Network Synthesis Essay
As wireless technologies continued to evolve, however, several standards, which govern wireless technology, were developed by the Institute of Electrical and Electronics Engineers (IEEE). The IEEE 802.11 Working Group (WG), for example, is responsible for specifying the family of standards for wireless LAN technology. The IEEE 802.11 WG’s main goals are to produce standards that encourage interoperability of products made by different vendors and to ensure that wireless LANs provide equivalent security as wired LANs. The following sections will limit its focus to the IEEE 802.11 family. It will then conclude with a brief overview of the 802.1X protocol, which is used to authenticate and authorize devices connecting to a network.
2.4.1 IEEE 802.11b

Although the IEEE 802.11a standard was introduced at the same time, it didn’t take on the same level of acceptance as 802.11b, even though it was capable of higher data rates. This is because 802.11a operated in the 5 GHz licensed band rather than the 2.4 GHz unlicensed band of 802.11b, which made it much more expensive. In addition, 802.11b supports data rates up to 11 Mbps, which is equivalent to traditional Ethernet. It’s important to also note that devices using 802.11b can experience interference with other devices operating in the 2.4 GHz band. For example: Bluetooth devices, cordless phones, microwave ovens, and even baby monitors can interfere with 802.11b signals, causing signal degradation and issues with

694 Words | 3 Pages5. METHODOLOGY 5.1 Secure Multipath Routing Protocols in Wireless Sensor Networks Till date many routing protocols have been proposed for wireless sensor networks, but only few of them consider the problem of security [4] and most of them are developed without any security concern. So in this section we focus at selected multipath routing protocols in order to cope with the various attacks. For avoiding intruders attacks in HWSN various methods and algorithms are implemented out of that Professor Hamid Al-Hamadi and Professor Ing-Ray Chen:

The difference between these wireless encryption is that WEP is wired equivalent privacy, a default procedure for wired security networks, WPA is an upgrade from WEP, and it is a wireless protected access to networks, whereas WPA2 is modernized into a more secure Wi-Fi from WPA. 2. With Static addressing, a computer (or other device) is configured to always use the same IP address, whereas dynamic addressing, the IP address can change periodically and is managed by a centralized network service.

Ece160 Unit 6 Essay
1391 Words | 6 PagesIntroduction The purpose of this report is to summarize what our team, the Fig Neutrons, did for the final project of ECE160. For the project we used an Arduino Sparkfun Kit to build a Simon says game with multiple game modes that would display several different game statistics on an LCD screen. The work the team has done includes Charlieplexing LEDs and including code for implementing the LEDs, writing code for a reverse Simon game. We also had to make the game play a different song than the one provided, and write code for the LCD to display wins, losses, game length, and the number of games played.

Another new aspect is challenger module will only allow one client to securely communicate with the server so communication architecture is peer to peer only but multiple clients can try to connect, so they will be connected to server but will not be authenticated to start messaging they have to wait for authenticated communication clearance one by one. Here the flow diagrams are described in two parts –First in Fig. 1 the generic communication model and in Fig.

598 Words | 3 PagesUnderstanding 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.

Summary Of Networking Isn T Always Easy By Liz Rappaport
602 Words | 3 PagesIn “Networking Isn’t Always Easy. But It Is Crucial” Liz Rappaport discusses how networking in business plays a key role in career advancement, especially for women, but is often much harder for them to do than for their male colleagues. Rappaport describes why women need to make a habit of building strong business relationships, maintaining them with regular following-up through social events and networking functions. These business relationships serve several important functions: gaining a forum to seek professional advice based on experience, garnering solid industry connections that provide later career advancement opportunities, and maintaining an expansive, robust business environment that promotes personal growth and development.
