Performance evaluation of ip wireless networks using two way active measurement protocol

With the advent of different kinds of wireless networks and smart phones, Cellular network users are provided with various data connectivity options by Network Service Providers (ISPs) abiding to Service Level Agreement, i.e. regarding to Quality of Service (QoS) of network deployed. Network Performance Metrics (NPMs) are needed to measure the network performance and guarantee the QoS Parameters like Availability, delivery, latency, bandwidth, etc. Two way active measurement protocol (TWAMP) is widely prevalent active measurement approach to measure two-way metrics of networks. In this work, software tool is developed, that enables network user to assess the network performance. There is dearth of tools, which can measure the network performance of wireless networks like Wi-Fi, 3G, etc., Therefore proprietary TWAMP implementation for IPv6 wireless networks on Android platform and indigenous driver development to obtain send/receive timestamps of packets, is proposed, to obtain metrics namely Round-trip delay, Two-way packet Loss, Jitter, Packet Reordering, Packet Duplication and Loss-patterns etc. Analysis of aforementioned metrics indicate QoS of the wireless network under concern and give hints to applications of varying QoS profiles like VOIP, video streaming, etc. to be run at that instant of time or not.
