Abstract
We analyze the performance of MAC-layer Reed-Solomon error-recovery in the cdma2000 1xEV-DO Broadcast and Multicast Services (BCMCS) environment, with respect to the size of the error control block (ECB) and the air-channel condition, and establish the relationship between ECB size, error-recovery capacity and service latency. Real-time traffic, such as voice and video streaming, is very sensitive to delay, but can stand a certain level of packet loss. We therefore propose an adaptive error-recovery scheme which adjusts the size of the ECB to reflect the environment of the mobile nodes so as to meet the required service quality (target bit error-rate), while reducing the latency of real-time applications, decoding complexity, and memory requirement. Extensive simulation results show the effectiveness of our adaptive approach compared to the current static scheme. Our scheme achieves near-optimal service latency while meeting the target service quality criterion, and also reduces energy consumption during error recovery.
