Handover mechanism of mobile WiMAX (802.16E) with Wi-Fi (802.11g) technology
IEEE802.16e (Mobile WiMAX) standard is proposed to support mobility, handover has
become one of the most important Quality of Service (QoS) factors. Applications
like mobile Voice over Internet Protocol (VoIP), multimedia gaming greatly benefits
from low-latency. To maintain such low-latency and keeping high QoS various advanced
handover schemes are being proposed and developed. The hybrid networks of Wi-Fi
and WiMAX can provide high data rate and enhanced multimedia services, but it is
challenging to obtain optimized handover decision based dynamic QoS information.
The first goal of this project is to implement various techniques used for handover
in mobile Wimax technology and compare the performance of such techniques in different
physical channel environment. The second stage of this project is to implement and
simulate the handover techniques from WiMax to WiFi without degradation in the QoS
i.e. maintaining the connectivity of the MS (mobile station) to either base station.
The third stage is the coordination of both technologies at the same time i.e. keeping
the MS (mobile station) connected to both technologies so that the SS (subscriber
station) feels the huge bandwidth available when both technologies are simultaneously
available. We will divide this project into 3 phases so we can build and model our
system in the right way for easy debugging. However, our first goal is to accomplish
the first stage, and as time permits we will continue the other phases. We intend
to complete our model with a full documentation as an open source for interested
students.
