Re: [v6ops] IPv6 multicast WiFi power usage - draft-desmouceaux-ipv6-mcast-wifi-power-usage

[Nabil Benamar <[e-mail]>]

Hi Yoann,

I really like your draft related to IPv6 multicast. Your current work could
become also a good research paper to be submitted to a good journal for
publication!

 As said in the Abstract: "Although the use of multicast does not create
real difficulties on wired networks, it can become painful on wireless
ones, notably in terms of power consumption" . This is a huge problem in
the case of constrained devices such in the Internet of Things. If the
sensors are in sleep mode they will nor receive all multicast messages and
then their IPv6 connectivity and performances could become intermittent !!

So in the introduction " this can have a negative impact on low-energy
devices such as

smartphones, as stated in [I-D.vyncke-6man-mcast-not-efficient]. The

802.11 protocol [IEEE80211]"  you can also mention the case of the
constrained devices (IoT) and the LLN (Low Power Lossy Networks).

more to come...
