  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Coexistence of beacon-enabled and nonbeacon-enabled PAN] Date Submitted: [12 July, 2008] Source: [Betty Zhao, Yongjun Liu, Zhihao Xing] Company [Huawei Technologies, Co., Ltd.] Address [Kuike Building, 9 Shangdi Xinxi Road, Haidian District, Beijing 100085] Voice: [86 10 82836907], Fax: [86 10 82836920], E-Mail: [betty.zhao@huawei.com] Re: [15-08-0373-01-004e-call-for-proposals] Abstract: [This document proposes an enhancement to IEEE 802.15.4-2006 MACto realize the coexistence of beacon-enabled and nonbeacon-enabled PAN.] Purpose: [This document is a response to Call for Proposals.] Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein.

  2. Coexistence of beacon-enabled and nonbeacon-enabled PAN Betty Zhao, Yongjun Liu, Zhihao Xing Huawei Technologies Co., Ltd. Huawei Technologies Co., Ltd.

  3. Outline • Motivation • Overview of beacon-enabled and nonbeacon-enabled PAN • Proposed solution for coexistence • Summary Huawei Technologies Co., Ltd.

  4. Motivation • Communicating obstacle between devices in beacon-enabled and nonbeacon-eabled PANs. • The beacon-based applications and nonbeacon-based applications need to coexist and collaborate. • Extension of a PAN is confined in a single mode now: beacon-enabled or nonbeacon-enabled. • We can achieve the coexistence by enhancing the function of several special devices. Huawei Technologies Co., Ltd.

  5. beacon-based applications nonbeacon-based applications Motivation: a simple example in home • The same problem exist in other areas, telecommunication, industry, … Huawei Technologies Co., Ltd.

  6. beacon-enabled PAN: A PAN in which all coordinators emit regular beacons. nonbeacon-enabled PAN: A PAN in which coordinators do not emit regular beacons. Network Device Network Device Coordinator Coordinator Beacon Data Data Data Request Data Request Data Data Overview of beacon-enabled and nonbeacon-enabled PAN (All ACKs are omitted. ) • It is no descriptions about communication and coexistence of the two kinds of networks in current Std. Huawei Technologies Co., Ltd.

  7. Problem • If a device in nonbeacon-enabled PAN wants to talk to another device in beacon-enabled PAN…What should it do? • Must the device disassociate from its PAN and join another PAN??? ? 10110101 Huawei Technologies Co., Ltd.

  8. Case 1: The Connection Device is both a device in beacon-enabled network and a coordinator in nonbeacon-enabled network. Promiscuous PAN: Connection Device Beacon-enabled PAN: Coordinator Device Communicate in beacon mode Nonbeacon-enabled PAN: Coordinator Device Communicate in nonbeacon mode Huawei Technologies Co., Ltd.

  9. Case 2: The Connection Device is both a device in nonbeacon-enabled network and a coordinator in beacon-enabled network. Promiscuous PAN: Connection Device Beacon-enabled PAN: Coordinator Device Communicate in beacon mode Nonbeacon-enabled PAN: Coordinator Device Communicate in nonbeacon mode Huawei Technologies Co., Ltd.

  10. Coexistence Promiscuous PAN: & Connection Device • Communication - In the promiscuous PAN, a device is able to talk to any other device without changing its beacon mode. So, • Application - The beacon-based applications and nonbeacon-based applications are able to coexist and collaborate. Huawei Technologies Co., Ltd.

  11. Summary • Separating beacon-enabled PAN and nonbeacon-enabled PAN is unnecessary. • Use “connection devices” to connect two kinds of PANs. • Based on “connection devices”, “promiscuous PAN” become a pretty solution for coexistence and communication between different devices. • It brings almost no change to current Std, such as MAC function and command.
