Todo

Project wide todo list

On this page we list all the items we normally have in our head, in small text files on our hard drives or scribbled on a piece of paper next to our keyboards. :-) Only high level items are listed here, the details can be found in the linked GitHub issues which we use for tracking.

wpan-tools (userspaces configuration utilities)

• Implement llsec kernel interface and expose it to the wpan-tools commandline (#2)
• wpan-ping: adjust maximal packet length automatically based on given configuration (address size, crypto, etc) (#4)
• PAN coordinator daemon to handle associated nodes, leases and configuration (depends on MAC command support in the kernel) (#5)

linux-wpan (Linux kernel implementation)

** Kernel drivers:**

• Remove cb context from dev_hard_header and introduce generic header generation functions like header_ops. Here too, crypto need to be done at first.
• Devicetree extended addr setting, draft is here ieee802154: add usual way to get extended address via device tree
• Bring XBee out of tree driver into mainline (#1)
• Change the cc2520 driver to xmit_async (#3)
• Update atusb driver to latest ieee802154_ops (#4)

Kernel 802.15.4 socket interface:

• Cleanup/fix 802.15.4 af raw/dgram socket code. We should use bluetooth socket code as example.

Kernel 802.15.4 SoftMAC layer:

• New frame parsing style in mac802154 and ieee802154 based on mac80211 frame parsing design.
• Support for beacon frames (#11)
• Support for MAC command frames (#12)
• Allow a node to scan for available PAN's (#13)
• Allow a node to act as PAN coordinator (#14)

Kernel 802.15.4 netlink userspace interface:

• In wireless exists a "station dump", we need something similar "node dump" with all neighbour nodes and their last LQI value, addresses, etc. information.

Kernel 6LoWPAN implementation:

• Add support for Generic Header Compression (RFC7400) (#6, #7, #8)
• Support ieee802154 short addresses for 6LoWPAN
• RFC6775

Misc

• On the 6LoWPAN side we need a configuration interface for all kind of compressions options (IPHC, NHC). A userspace utility is also needed for this and should not be bundled with wpan-tools as it should be generic for all kind of 6LoWPAN adaptation layers.
• Support for raven usb stick inside ATUSB firwmare (code is done, awaits v0.3 release of the atusb firmware)
• Develop firmware for CC2531 usb stick comparable to the ATUSB firmware
• Research potential for IEEE 802.15.4e support inside Linux and work on a proof of concept (#9, #10)

Interoperability

• Develop test cases for interop with RIOT
• Develop test cases for interop with Contiki

External projects we might interface with

• systemd: add basic functionality for nl802154 and 6LoWPAN setup in systemd-networkd
• network-manager: add basic functionality for nl802154 and 6LoWPAN setup if needed (#22)
• connman: add basic functionality for nl802154 and 6LoWPAN setup if needed (#23)
• unstrung: RPL implementation.
