TinyOS 2.0 Network Protocol Working Group

We define the programming interfaces to network protocols in TinyOS 2.x, specify and document protocols to support interoperability between different implementations, and provide and support reference protocol implementations in TinyOS 2.x. So far, we have released CTP, MultihopLQI, Drip, DIP, and Deluge protocols.

Charter

The TinyOS 2.0 Network Protocol Working Group (net2) is responsible for

• defining the programming interfaces to network protocols in TinyOS 2.x,
• specifying and documenting protocols to support interoperability between different implementations, and
• providing and supporting reference protocol implementations.

Relevant TinyOS Enhancement Proposals (TEPs)

• In TinyOS, TEPs are used to document and standardize OS implementations, interfaces, mechanisms, and programming conventions. The Network Protocol Working Group has contributed TEPs that propose, document, and specify network protocols. The TEPs are available at http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-2.x/doc/txt.

Group Membership

If you'd like to join the WG, you should send an email to the net2 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.
