摘要： A beacon assisted asynchronous method of wireless communication according to the present invention enables initiating and target devices (12, 14) to remain in sleep mode most of the time and to periodically wake up to asynchronously, and directly, communicate with one another. Specifically, each of the initiating and target devices (12, 14) transmits a beacon while operating in a default transmit/receive mode (40, 40a, 42, 42a) and subsequently listens for a response. Alternatively, the initiating device (12) may enter a data packet message mode to receive a beacon from the target device (14) and to subsequently transmit a data packet message to the target device (14) after receiving the first beacon. The initiating device (12) minimizes the length of time in which it must wait to receive the target device beacon by timing a corresponding target beacon receive period based on stored data such as information based on previous communication with the target device (14).

摘要： A method and apparatus for removing phantom children in an ad-hoc network is described herein. During operation messaging between the parent and child nodes allows the parent node to detect when a node has become a phantom node, and take action to correct it. In particular a maintenance message is periodically transmitted by every node in the network to its parent. The maintenance message is designed to inform the parent of at least a unique identifier of the child. The parent can then compare this unique identifier of the child to others associated with the parent to determine if the child is the real child or a phantom child. Corrective action is taken when a phantom node is detected.

摘要： When a requesting node (402) has routing capabilities and attempts to join a network and there are no association slots available, the requesting node (402) will send an association message to a potential root node (401). If the root node (401) has reached the maximum number of links, and has a non-routing capable node (403) associated with it, the root node (401) will send a message to the non-routing capable node (403), instructing it to disassociate and attempt to re-associate at a later time. A message is then sent to the requesting node (402) for it to associate with the root node (401).

摘要： A first image (200) of a transmitted signal is detected within a received signal containing a plurality of images of the transmitted signal. This is accomplished by detecting a second image (210) of the transmitted signal. A set of characteristics of the second image of the transmitted signal is determined, and subsequently used to detect the first image (200) of the transmitted signal.

摘要： In order to set up efficient routes between two closely-located nodes an optimized route for two nodes within a hybrid-cellular network (HCN) is achieved by converting an HCN route to an ad-hoc route. Thus, a node within the communication system may originally be communicating with another node via an HCN route and then instructed to switch to a more efficient ad-hoc route for communication with the node.
摘要翻译：为了在两个紧密定位的节点之间建立有效的路由，通过将HCN路由转换为自组织路由，实现混合蜂窝网络（HCN）内的两个节点的优化路由。因此，通信系统内的节点最初可以经由HCN路由与另一节点进行通信，然后被指示切换到用于与节点通信的更有效的自组织路由。
