Abstract:
Multicast is one of the most efficient ways to distribute data to multiple users. There are different types of Multicast such as IP Multicast, Overlay Multicast and Application Layer Multicast (ALM). In this study, we focus on Application Layer Multicast where the multicast functionality is implemented at the end user. We introduce a new ALM protocol, Link Aware-NICE (LA-NICE), which is an enhanced version of the NICE protocol. NICE is a recursive acronym which stands for NICE is the Internet Cooperative Environment. LA-NICE protocol takes into account the fact that different links can have different bandwidths and this fact can be used to improve multicast message delivery and minimize end-to-end delay. OMNeT++ simulation framework was used to evaluate LA-NICE. The evaluation is done through a comparison between LA-NICE and NICE. The simulation results showed that LA-NICE produces an increase in the percentage of successful message delivery ranging from 2% to 10% compared to NICE. Also, LA-NICE has less average delay and less average message hop count than NICE which reduces the overall latency of message delivery.
