Throughput Analysis of WLAN with Network Coding

Abstract

Network coding is a new concept of combining theinformation at intermediate nodes, which can increase thethroughput of the network. In this paper we apply networkcoding techniques to Wireless LAN (WLAN). Network codingis applied at the access node of a 7-cluster WLAN and theprobability of network coding feasibility is arrived at. Furtherqueuing theory is applied to analytically obtain the WLANthroughput both in the presence as well as absence of physicalchannel induced transmission errors. From the analysis it isobserved that application of network coding to WLANincreases the throughput by 5 to 7% as compared to traditionalstore and forward routing

Queuing Theory Approach for Evaluating Rate of Transmission in Wireless Network Using Network Coding

“…The transmission rate in the wireless network using 11 number of routers shows an improvement to the wireless network using less number of routers. Conventional routing shows good network performance both in this analysis and in [1]. Adding network coding makes it more accurate in performance.…”

“…The result obtained from our analysis is to be compared with a specific literature [1]. The transmission rate in the wireless network using 11 number of routers shows an improvement to the wireless network using less number of routers.…”

“…Stable rate of transmission is defined as the greatest possible quantity of packet generation at which the packet attain their respective destination with minimal predictable delay [1].…”

“…Wireless LANs have some varieties of smaller forms sometimes called "Personal Area Networks", this is because their basic purpose is to typically serve an individual that is connecting a laptop computer or personal digital assistance to a desktop machine [1][2].…”
