A Study of the Impact of Traffic Type, Node Mobility and Handoff on the Performance of Mobile WiMAX Network
IEEE 802.16e, mobile WiMAX is a wireless technology used to provide very high data rate over large areas to larger number of users where broadband is unavailable. It is an attractive solution for providing high-speed internet access in a cost-effective way to people living in both sparsely populated rural areas as well as densely populated urban areas. This popularity is a result of the flexibility, low-cost and user mobility offered by the technology. This paper analyses mobile WiMAX performance for small, medium and large network scenarios under FTP, HTTP, VoIP and video conferencing traffic with varied node mobility (0-90km/h) when handoff is enabled or disabled through extensive simulation experiments.
