Associated devices information element and faster association

Associated Devices Information Element and Faster Association

17 March, 2004

Manoj Choudhary, SISO/SAIT


Abstract

Abstract

  • We propose an Associated Devices Information Element (ADIE) in the beacon frame that conveys association status of all devices (DEVIDs) in the piconet.

  • We propose a faster association procedure using Associated Devices Information Element (ADIE).

  • The proposed Associated Devices Information Element (ADIE) may be used for some other purposes also.

  • Summary

Manoj Choudhary, SISO/SAIT


Current solution 1

Current Solution (1)

  • Beacon frame

    • There is a clerical error in the draft diagram (L1 is shown as Lm)

    • Beacon is sent by PNC at the start of all the superframes

    • Beacon contains different Information Elements (IEs).

      • Details about beacon frame: Reference Section 7.3.1 in Draft P802.15.3/D17, February 2003

Manoj Choudhary, SISO/SAIT


Current solution 2

Current Solution (2)

  • These IEs are encoded in type, length, value format. The IEs in the beacon payload may appear in any order except for the channel time allocation (CTA) IEs

    • Element IDs 0x00 to 0x0F: Already assigned

    • Element IDs 0x10 to 0x7F: Reserved

    • Element IDs 0x80 to 0xFF: Vendor specific

      • Details about Element IDs: Reference Table 48 in Draft P802.15.3/D17, February 2003

      • Details about Information Elements: Reference Section 7.4 in Draft P802.15.3/D17, February 2003

Current association procedure reference section 8 3 1 in draft p802 15 3 d17 february 2003

Current Association Procedure (Reference Section 8.3.1 in Draft P802.15.3/D17, February 2003)

Manoj Choudhary, SISO/SAIT


Problems with current solution

Problems with Current Solution

  • Longer and centralized association procedure

  • New node (trying to join) does not have information about associated nodes in the piconet and their DEVIDs

Manoj Choudhary, SISO/SAIT


Proposed solution

Proposed Solution

  • Associated Devices Information Element (ADIE)

    • Purpose of this IE is to provide the information about all associated devices in beacon

    • Element ID of ADIE is 0x10 (Which is taken from reserved pool of Element IDs).

      • Details about Element IDs: Reference Table 48 in Draft P802.15.3/D17, February 2003

Manoj Choudhary, SISO/SAIT


Format of associated devices ie adie

Format of Associated Devices IE (ADIE)

Total Length of ADIE (bytes) = ((2 ^ Length of DEVID field in bits) / 8) + Size of Length field + Size of Element ID field = ((2 ^ 8) / 8) + 1 + 1 = 34

Manoj Choudhary, SISO/SAIT


Proposed beacon with adie

Proposed beacon with ADIE

Proposed association procedure

Proposed Association Procedure

  • By using ADIE, new DEV can find out unused DEVIDs.

  • New DEV can choose a random DEVID from the unused DEVIDs and should propose it as its DEVID to PNC.

  • So, Association Response can be a directed message, which is broadcast in current specification.

Summary

Summary

  • We propose an Associated Devices Information Element (ADIE) in the beacon frame that can tell about all associated devices and their DEVIDs in the piconet.

  • We propose a decentralized and faster association procedure using Associated Devices Information Element (ADIE).

  • The proposed Associated Devices Information Element (ADIE) may be used for some other purposes also like routing extensibility.
