Project goalThe wireless profit is highly dynamic , the tote up of examplers in each introduction point is changing in all the judgment of conviction and therefore those kinds of profits requires a powerful counsel tool that gives the network managing director the capability to control the network in truly time from anywhereThe project goal was to en carapace a web application (using Microsoft .NET environment ) that leave completely provide easy admission for network counselling to the network managerThe application implys 3 modulesMain application - this module includes the network manager interface such as the login window , applyr management functions and doorway Point management functionsDatabase interface - this module deals with the access to the database using SQLAccess point material body - this module deals with the access to the Access Points in to get or set the Access Point properties using the SNMP protocolLater on , a detailed history on each of these modules lead be given2 .

11 protocol is defined for a wireless LAN (Local airfield Network and is based on a carrellular architecture in which the network is divided into cells where each cell (called a fundamental Service Cell (BSS ) is controlled by a base discount called an Access Point (APThe basic access mechanism apply in the protocol is a toter Sence Multiple Access with Collision Avoidance (CSMA /CA . The CSMA protocol works as follows : if a come out wishes to transmit cultivation by means of it network , it senses the sensitive . In study the medium is busybodied (another rank in the network is currently transmittal breeding then the set will delay its contagion clear ups to a later time Ot herwise , the medium is justify and the station is allowed to transmit the desired informationThe problem with the CSMA protocol is the case where a collision guides A collision may pop off if two different stations sense the medium as free and begin to transmit information . For this purpose , we use a collision avoidance mechanism : a station willing to transmit senses the medium . If the medium is busy , it defers its postulate . Otherwise , it sends an RTS (Request To Transmit ) which includes the source , destination and the duration of the dealing . If the medium is free then the destination station will respond with a packet called CTS (Clear To Send ) which will include the same duration information and once the source station receives this...If you want to get a full essay, order it on our website: BestEssayCheap.com
