Abstract:
This is a working document intended to focus discussion on
requirements for multicast in Low-power and Lossy Networks in the
area of M2M communication for control applications. The Trickle
algorithm, which uses random re-broadcasting to assure that messages
arrive at all destinations, has been proposed in the Trickle
Multicast Forwarding ROLL WG draft as the basis for a multicast
routing protocol. In this draft additional requirements on multicast
routing are presented, such as timeliness, motivated by building
control. Random re-broadcasting and timeliness can be difficult to
reconcile. This draft presents some simulation results in typical
control settings which show that achieving latencies below 400 ms is
feasible with Trickle. Recommendations are proposed for the current
Trickle Multicast Forwarding draft to achieve optimal performance and
meet the stated requirements.
