Prediction-based routing for real time communications in wireless multi-hop networks

Shouyi Yin, Yongqiang Xiong, Qian Zhang, Xiaokang Lin
2006 Proceedings of the 3rd international conference on Quality of service in heterogeneous wired/wireless networks - QShine '06  
By selecting route with minimal PPTT, the quality of service for the coming RTC flow will be improved, in terms of end-to-end delay and goodput.  ...  In this paper, we propose a novel prediction-based routing metric, PPTT (Path Predicted Transmission Time), to estimate end-to-end delay of RTC traffics.  ...  Thus the measurement based routing schemes can not reflect path quality accurately.  ...
