FEC, ARQ module (maybe create a separate kernel module, port also the link layer fragmentation to this module so other protocols might use it?) +* Dynamic OGM/NDP intervals +* Dead-node fast path switching +* Link quality / Packet delivery ratio measurement improvements + -> weighted/exponential moving average + -> testing / performance measurements of / improving NDP, find and improve "performance bottlenecks" +* Multicast Optimization Algorithm enhancements + -> implement reactive tracker packet mode + -> decrease latency of reactive tracker packet mode: attaching small data packets to tracker packet, if MTU fits (otherwise broadcast) in react. mode? ...? + -> ultimately, make proactive tracker mode obsolete + -> optimize number of rebroadcasts (we have the info about the number of next hop nodes) + -> don't send tracker packets if <= 1 destination or > 50%25 of all nodes are destinations + -> Enhance HNA, host network announcements, improvement scheme to also support MCAs, multicast announcements + -> ... +* Implement a suitable solution against hidden node broadcast packet problem (time slots, multiple interfaces, channel switching (extra module?), ...) +* Implement a suitable congestion avoidance mechanism for batman's control packets (different queues for control and data packets, time slots, ...) +* Unit test infrastructure (Implementation centric tesitng, simulator using Linux VMs to test different topologies or administrative changes? Code centric unit tests ...) +* Separate routing algorithm from routing infrastructure (ultimately, allow user space routing protocols to interact with kernel routing framework) +* Bonding improvements: + -> Add checks for links' capacities (detect full queues etc.) to gain performance of IF1 + IF2 + ... instead of min(IF1, IF2, ...) (example to have 1gbit/s (ethernet) + 100mbit/s (802.11n wifi) instead of just the minimum of all interfaces) + -> Improve bonding mode gain (seems to be just 66%25 efficiency with TCP due to reordering problem?) +* IPv6 stateless autoconf GW solution (playing with TTL of broadcast packets, use router preference option in RA (RFC4191)?) +* Further HNA roaming improvements +* Network Coding? + +== batctl == +* Enhance live link quality monitoring: bisect -> dot-files -> graphs -> to (live) video? (+ adding horst tool information, wifi interface stats?) +* Add further info to batman-adv vis servers/clients for debugging networks +* bisect, include initial state +* live vis in map (HTML5 + Openstreetmap?) + +== misc == +* multiple interface support in Mesh 3D +* ap51flash GUI; ap51flash multi-flash on single interface +* Android/Maemo/Meego porting + _maintenance_! +* Cooperative work with Pidgin guys?
