A real-time traffic scheduling algorithm in CDMA packet networks

The demands for multimedia and packet data services over wireless devices have increased over the past few years. The direct impact on performance makes scheduling for real-time traffic important. This paper presents a novel scheduling algorithm called fair channel-dependent scheduling which schedules packet delivery to mobile stations in a fair manner and at the same time takes into consideration the channel conditions for power efficiency. With added delay information for real-time traffic, this approach aims at delivering real-time traffic in a timely manner, while maintaining a balance between power conservation and fairness. Through comparative simulations with two conventional scheduling algorithms, we show that our scheme indeed achieves better overall performance than comparable scheduling schemes.
