Abstract
On-demand broadcast is an effective data dissemination approach in mobile computing. Recently, a large number of mobile applications have been developed in broadcast systems equipped with multiple channels. Therefore, it becomes a critical performance consideration for the underlying scheduling algorithm to utilize bandwidth efficiently in multi-channel on-demand broadcast environments. However, we find that existing scheduling algorithms fail to utilize bandwidth efficiently in this new environment and it results in a poor system performance. In this paper, we examine this bandwidth utilization problem. Based on the observation, we propose a bandwidth-efficient scheduling algorithm called COS in multi-channel on-demand broadcast environments. Results from our simulation study demonstrate the superiority of COS.
