TinyOS 15.4 WG

The goals of the 15.4 WG are:

• to develop and maintain a platform-independent, standard-compliant implementation of the IEEE 802.15.4-2006 MAC
• to make the implementation available on (appropriate) TinyOS 2 platforms and TOSSIM

• to align the MAC interfaces with the next-higher layers in TinyOS 2 (AM, prospective ZigBee NWK, 6lowPAN)

• to provide mechanism to integrate enhancements / variants / add-ons to the MAC protocol (e.g. QoS, traffic differentiation mechanisms, frequency agility and coexistence)

The basis for the implementation is the code located in: tinyos-2.x/tos/lib/mac/tkn154 (TinyOS 2 CVS)

Goals for 2009

• define radio driver interfaces (interfaces that a radio chip abstraction must provide to the MAC),
• finish the baseline implementation (including (non)beacon-enabled mode, but without GTS / security),
• start validation through interoperability tests with certified 15.4 MAC protocols (e.g. TIMAC),
• improve code documentation, extend example applications, create a documentation Wiki, write a TEP
• make the implementation available in TOSSIM,
• implement security / GTS,
• align MAC interfaces with next higher layers in TinyOS 2

Group Membership

If you'd like to join the WG, you should send an email to the 15.4 WG chair, who will forward the message to all members for discussion. Admittance is based on group consensus. When consensus is reached, a member of the WG will forward the group's decision to you. General considerations include expected degree of participation, prior work, and area of expertise with respect to the rest of the WG.

Overlap and Interactions

A platform-independent 15.4 MAC implementation will require (a) a set of radio interfaces provided by the radio chip abstraction and (b) alarms/timers with symbol resolution and conforming with the accuracy requirements of the standard. Radio/Timer chip abstractions are defined by the core WG, thus there will be interaction with the core WG. In addition, there will be interaction with prospective ZigBee WG and core WG on aligning the MAC interfaces with the AM and ZigBee layers.
