Abstract

This project discusses about an experimental test bed for voice over IP in Wireless LAN environment. This includes setting a multi hop mode for wireless communication and using Linux as an operating system. The metrics to evaluate are streaming, unidirectional, bidirectional request and responds of VolP in an Ad-Hoc WLAN network. The experiment setup includes three nodes in the wired and wireless network. Voice requires low end-to-end delay, jitter and percent packet loss. Voice receives strict priority servicing, and the amount of priority bandwidth assigned to it should take into count the VolP codec. The packet that include IP, UDP headers and Layer 2 overhead are the minor criteria effect the bandwidth and rate of packet through the network. Additionally, delay jitter, packet error and packet loss are effeted by node and the network infrastructure. To analyze the packet flow characteristic, few program which include Ethereal, Netperf, and Iperf to measure the throughput, bandwidth, delay, jitter, packet error and packet drop. The IPv6 has been developed to replace the current IPv4 protocol. Various operating systems running at end-systems now support IPv6 protocol stacks and network infrastructures (hosts, routers) are currently being deployed to support IPv6 features. To investigate the impact of IPv6 on VoIP, an empirical evaluation was conducted on the performance of IPv4 and IPv6 protocol stacks on the Linux operating system for UDP protocols. The IPv6 performance obtained on Linux was compared with the performance of IPv4. The experimental results on WLAN also been taken demonstrate that IPv6 protocol stack for Linux giving the capability to delivery UDP packet. The experimental result show that the current codec and WLAN are able to support voice streaming and conferencing.
