The Network Simulator NS-2 is a versatile extendable tool that is widely used in the networking community. It provides support for simulation of many protocols over networks including 802.11e. To investigate network performance, researchers can configure a network scenario with an easy-to-use scripting language, and then observe results generated by NS-2. This paper outlines plans to investigate how synchronized time implemented in end terminals can aid in optimizing 802.11e parameters to improve QoS for VoIP. In particular this paper will look at the Network Simulator (NS-2), and outline the plans to build an extension to the open source simulator.
