Wireless broadcast data scheduling in environment with re-attempt users: Optimization through intelligent feedback monitoring
(2001)Most of the previous work on wireless broadcast data scheduling has been based on simplified assumptions regarding mobile user behaviour. In this paper, we show that the employment of a realistic mobile user behaviour model ...
