摘要： An advance over the prior art is achieved through an efficient method for an admission control algorithm and a scheduling mechanism that complement each other in providing the following three classes of service. A first class of service is termed Class 1 where users specify a nominal amount of bandwidth desired. A second, lower tier service class is termed Class 2, wherein users specify a nominal and minimum amount of bandwidth desired when entering into a network connection. A third server class is Class 3, where Class 3 users are treated as best effort users. For Class 1 users the methodology of the present invention provides a guaranteed nominal amount of bandwidth. The admission control procedure ensures that Class 1 users are admitted only if resources exist to satisfy the nominal bandwidth requirements of the Class 1 users. Class 2 users are admitted if resources exist to satisfy the minimum bandwidth requirements of the user. Class 2 users are served with a bandwidth of up to their nominal bandwidths if there is capacity left after serving the Class 1 users with their nominal capacities. Class 3 users are served only if the Class 2 users have received their nominal bandwidths.

摘要： A clustering based load adaptive sleeping protocol for ad hoc networks includes a plurality of nodes forming a cluster, where the nodes in the cluster are partitioned into n groups. This partitioning is performed based on the node ID (e.g. node_id modulo n). The cluster head transmits a beacon at fixed intervals. The beacon interval is divided into N slots, where N is a multiple of n. Node sleep/activation times are synchronized to the beacon interval slots. The node's group number is used to determine the slots within a beacon interval that a node begins it s sleep cycle. Therefore, no additional signaling is required between nodes to indicate sleep patterns. The sleeping time of each node may be increased when extended periods of inactivity are detected according to an adaptive procedure.

摘要： An advance over the prior art is achieved through an efficient method to retransmit erroneous frames by identifying the users who are most likely to experience a frame error and requests retransmissions from them. Since the recovery is done by starting with the most likely, second most likely etc., the invention results in faster recovery of data. Moreover, the invention reduces the battery consumption of subsequent mobile nodes by suppressing the retransmission requests that were already made by nodes preceding it. A key element of the invention is to rank the set of receiver nodes in the order of decreasingly worse channel conditions, i.e., from worst to best. Hence, with K receiver nodes, a transmit node assigns rank 1 to a receiver node to which it has the poorest radio channel condition. Similarly, it assigns rank K to the receiver node to which it has the best radio channel condition. The channel condition is known at the receiver by keeping a simple measure of the number of data frames correctly received so far and the total number of frames transmitted to it. This information can be periodically sent back to the transmitter and thus aiding in the ranking procedure. Alternatively, if the transmitter is capable of sending a pilot/beacon, the receiver can do some averaging of received signal strength and provide such information back to the transmitter.

摘要翻译： 通过有效的方法通过识别最有可能经历帧错误并请求重传的用户重传错误帧来实现现有技术的进步。 由于恢复是通过从最可能的，最可能的次数等开始来实现的，所以本发明导致更快的数据恢复。 此外，本发明通过抑制已经由节点之前已经做出的重传请求来减少后续移动节点的电池消耗。 本发明的一个关键要素是以越来越差的信道条件，即从最差到最佳的顺序对接收机节点集进行排序。 因此，对于K个接收器节点，发射节点将秩1分配给具有最差无线电信道条件的接收机节点。 类似地，它将等级K分配给具有最佳无线电信道条件的接收机节点。 通过保持对到目前为止正确接收的数据帧的数量的简单测量以及发送给它的总帧数，在接收机处知道信道条件。 该信息可以周期性地发送回发射机，从而辅助排序过程。 或者，如果发射机能够发送导频/信标，则接收机可以对接收到的信号强度进行一些平均，并将这些信息提供给发射机。

摘要： Method and apparatus for routing messages in a network includes first filters to provide frequency-based message signals converted from an optically-based signal and mixers adapted to mix the frequency-based message signals with sub-carriers to generate frequency-based sub-carrier modulated message signals. A frequency generator connected to the mixers provides the sub-carriers to the mixers and a combiner connected to the mixers combines the frequency-based sub-carrier modulated message signals. Second filters connected to the combiner receive and group the frequency-based sub-carrier modulated message signals. Optical transmitters connected to second filters optically convert and transmit the frequency-based sub-carrier modulated message signals. The frequency generator generates and applies a particular sub-carrier frequency to one of the mixers according to information contained in the frequency-based message signal. The information is encoded into the frequency-based message signal via a generalized MPLS (GMPLS) label contained in a header portion of the frequency-based message signal.
