摘要： There is disclosed a wireless communication apparatus that does not interrupt synchronous communication but can continuously perform the synchronous communication even when an address duplication occurs between the local wireless communication apparatus and a nearby wireless communication apparatus. A plurality of wireless communication apparatuses constitutes an ad hoc network system where they transmit beacons to each other. In the wireless communication apparatus, an address processing part (145) generates a first address, which includes a beacon period slot number corresponding to the position-on-beacon-period of a beacon generated by the local wireless communication apparatus, and a second address assigned at random. A beacon processing part (140) determines whether the second address generated by the address processing part (145) is coincident with a second address at another wireless communication apparatus. A transmitting part (170) uses one of the first and second addresses generated by the address processing part (145) to transmit a frame to the other wireless communication apparatus.

摘要： A beacon slot position control section of a radio communication apparatus constituting a radio network system which detects whether empty beacon slots are present in a beacon period. When an empty beacon slot is present before the period in which the radio communication apparatus transmits a beacon, a movable counter starts counting a specified number of super frames. When the count is completed, the radio communication apparatus transmits a beacon of the radio communication apparatus at the earlier empty beacon slot. Consequently, since the empty beacon slots are eliminated and the beacon period is compacted, even if the number of radio communication apparatuses joining the radio network system fluctuates dynamically, the radio communication apparatus can perform radio communication with high efficiency and less waste of consumed electricity.

摘要： Provided is a radio communication method which can reduce the power consumption as compared to the conventional technique while realizing coexistence of a plurality of radio communication methods and can perform synchronization with a super frame of other radio communication device. The super frame has life confirmation slots (2820, 2830) through which radio communication devices of various modulation types should transmit tone signals. A radio communication device has a chance to judge whether one or more radio communication devices using a different modulation type exist or no such device exists in the vicinity. If no such device exists, the slot to be used by the radio communication device of the modulation method is reported as a time that can be used by a radio communication group of other modulation method. Thus, by confirming existence of an object in the vicinity by other radio communication device with which communication cannot be performed, communication can be performed by sharing the super frame.

摘要： Provided is a radio communication method capable of optimally using the wide-band communication enabled time while maintaining power saving in an ad hoc network. According to this method, in the ad hoc network using the wide-band communication and a narrow-band communication, transmission and output of the narrow-band synchronization tone signal and the resynchronization tone signal are controlled so that the reach radius of the narrow-band synchronization signal and the resynchronization tone signal exceeds the reach radius of the wide-band signal (milli-wave UWE signal). Thus, when radio communication devices pass by each other, super frame synchronization is completed before reaching the wide-band communication enabled range of the ad hoc network, thereby optimally using the wide-band communication-enabled time.

摘要： A frame such as a beacon in wireless communication, with a maximum MAC address, hop count, and maximum hop count, described therein is exchanged between nodes. All the nodes measure the number of hops from a node with the maximum MAC address, and exchange the maximum hop count (hmax) out of the numbers with each other. Hop count H(a,b) between arbitrary nodes a and b is expressed by H(a,b)≦H(a,max)+H(max,b)≦2*hmax, where hmax is a hop count from node (max) with the maximum MAC address to the farthest node. That is, the number of hops between two arbitrary nodes in the group is always 2*hmax or less. Herewith, a numeric value assuredly exceeding the maximum value out of the numbers of hops between nodes in an ad-hoc network can be propagated in the entire ad-hoc network.
摘要翻译：诸如无线通信中的信标的帧，其中描述的最大MAC地址，跳数和最大跳数在帧之间在节点之间交换。所有节点测量具有最大MAC地址的节点的跳数，并将数字中的最大跳数（hmax）彼此交换。任意节点a和b之间的跳数H（a，b）由H（a，b）<= H（a，max）+ H（max，b）<= 2 * hmax表示，其中hmax是跳数从最大MAC地址到最远节点的节点（max）。也就是说，组中两个任意节点之间的跳数总是为2 * hmax或更小。因此，可以在整个ad-hoc网络中传播确定超过自组织网络中的节点之间的跳数的最大值的数值。

摘要： A wireless communication method wherein the power consumption can be reduced as compared with the conventional one and a wireless communication apparatus can synchronize its super-frame with the super-frame of another wireless communication apparatus in an ad hoc network. According to this method, in the ad hoc network where a plurality of wireless communication apparatuses use broadband signals to data-communicate with each other, a wireless communication apparatus transmits an end tone (201) for identifying the end of a super-frame (221), and when another wireless communication apparatus receives the end tone (202), it synchronizes the end of its super-frame (221) with the end of the foregoing super-frame (221). In this way, the super-frames (221) can be synchronized even without any beacons.
