Application-layer versus Network-layer Multicast: Networking Load, Link Stress, and Distribution Delay
DownloadFall 2017
Multicast is the task of disseminating a message from a source to a set of destinations. If supported by the network and switches, multicast can be performed at the network layer. The alternative solution is application-layer multicast (ALM) which disseminates the message through a set of unicast...

Wireless relays offer benefits such as coverage extension and improving robustness. Selection of relays may provide further benefits. The best relays are selected based on the channel state information. However, due to feedback or scheduling delays, in practise, the relay and/or the source node can...
