28、onal Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards. Their preparation is entrusted to technical committees; any ISO and IEC member body interested in the
29、 subject dealt with may participate in this preparatory work. International governmental and non-governmental organizations liaising with ISO and IEC also participate in this preparation. 2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC
30、 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. 3) The formal decisions or agreements of IEC and ISO on technica
31、l matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC and ISO member bodies. 4) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and ar
32、e accepted by IEC and ISO member bodies in that sense. While all reasonable efforts are made to ensure that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 5
33、) In order to promote international uniformity, IEC and ISO member bodies undertake to apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any ISO/IEC publication and the corresponding national or re
34、gional publication should be clearly indicated in the latter. 6) ISO and IEC provide no marking procedure to indicate their approval and cannot be rendered responsible for any equipment declared to be in conformity with an ISO/IEC publication. 7) All users should ensure that they have the latest edi
35、tion of this publication. 8) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts and members of their technical committees and IEC or ISO member bodies for any personal injury, property damage or other damage of any nature whatsoever,
36、whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC publication or any other IEC, ISO or ISO/IEC publications. 9) Attention is drawn to the normative references cited in this publication. Use of the re
37、ferenced publications is indispensable for the correct application of this publication. 10) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such pa
38、tent rights. International Standard ISO/IEC 29145-2 was prepared by subcommittee 25: Interconnection of information technology equipment, of ISO/IEC joint technical committee 1: Information technology. The list of all currently available parts of the ISO/IEC 29145 series, under the general title Inf
39、ormation technology Wireless beacon-enabled energy efficient mesh network (WiBEEM) for wireless home network services, can be found on the IEC web site. This International Standard has been approved by vote of the member bodies, and the voting results may be obtained from the address given on the se
40、cond title page. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 6 ISO/IEC 29145-2 ISO/IEC 2014 INTRODUCTION This International Standard specifies the WiBEEM (Wireless Beacon-enabled Energy Efficient Mesh network) protocol, which provides low-power-consuming mesh
41、 network functions by enabling the “beacon mode operation”. WiBEEM is based on IEEE 802.15.4 standard with additional upper layer protocols and a specific usage of the MAC layer protocol. Through the novel use of beacons, WiBEEM technology achieves longer battery life, larger network support, quicke
42、r response, enhanced mobility and dynamic reconfiguration of the network topology compared with other protocols such as ZigBee. In the beacon mode, Beacon information propagates over the entire mesh network nodes during the BOP (Beacon-Only Period) of the superframe structure without any beacon conf
43、licts by utilising a smart beacon scheduling technique in the BOP. It also provides location information about moving devices without spending extra time running a positioning and locating algorithm by using RSSI (Received Signal Strength Indication). These features allow the WiBEEM protocol to be w
44、idely used for wireless home network services in the ubiquitous network era. One of the key features of the WiBEEM protocol is that it has a special time interval called BOP (Beacon-Only Period) in the superframe structure that allows more than two beacons to be transmitted. This unique time period
45、is located at the beginning of the Superframe. Because the BOP does not use the CSMA/CA mechanism, the network will not work properly in the beacon mode unless an appropriate algorithm is applied. This algorithm needs to manage and control multiple beacons in a single superframe. The solution is the
46、 Beacon Scheduling method applied in the BOP to avoid collisions among beacons, providing synchronisation among all the nodes of the entire mesh network. For the network layer, the NAA (Next Address Available) mechanism, which is a short address allocation algorithm, has been adopted to provide an e
47、fficient way of utilising the complete 16- bit address space. The NAA algorithm does not limit the maximum number of children nodes that a node of a mesh network can have. Since the number of children nodes is unlimited, the NAA mechanism allows the WiBEEM protocol to be used not only for home netwo
48、rk services, but also for community services. WiBEEM can be used where high network expandability through efficient use of short address spaces, device mobility and end-to-end QoS are required. This part of the standard ISO/IEC 29145 specifies the Medium Access Control (MAC) layer of the WiBEEM prot
