No. 802.11s is implemented at the datalink layer (actually inside the mac80211 kernel module) and provides you a way to establish a connection with other peers. With batman-adv you first need to establish the connection with the other nodes by means of adhoc or infrastructure mode (or any other kind of connection that creates a virtual Ethernet interface). Therefore when using batman-adv (or batmand or bmx6) you first need to establish a datalink layer connection and then you can use the protocol on top of it. In the case of 802.11s the datalink connection is handled by itself directly. I would say that it is a small difference, but then the sentence would be: "{batman-adv + adhoc mode} is an alternative to 802.11s" batman-adv took this approach because we believe that there is no need to re-implement something that we already have (e.g. adhoc mode) and at the same time this gives batman-adv more flexibility (it can be used also on top of wired Ethernet interfaces).

This is fine, if someone like Google or Cyanogenmod would enclude batman-adv in their Android builds, which would merely require to enable building the module in the kernel build process, as it is shipped with the vanilla kernel sources. >> >> batmand and bmx6 are user space programs that merely alter the routing table.
