摘要： A communication system for point to multipoint communications by grouping client devices based on associated modes is provided. In one example implementation, point to multipoint communication improvements are achieved by grouping a plurality of client devices by their optimal modes for communication. For example, the communication system can determine, based on channel quality indicators (CQIs) that two client devices of a plurality of client devices are associated with an optimal first mode of a modal antenna. The system can group the two client devices into a first group, the first group associated with communication using the first mode of the modal antenna. The modal antenna can communicate with the first group using the first mode of a modal antenna during a single frame of communication.

摘要： The present invention relates to a method of, and device for, arranging a P2P network comprising a streaming source and network peers arranged at distribution levels in the P2P network, in which P2P network the streaming source is arranged to divide data content to be streamed into a plurality of content sub-streams together forming the data content and to distribute the plurality of content sub-streams to the network peers. The method comprises instructing a network peer requesting to download data content to download a single content sub-stream from a respective one of selected network peers being arranged at a distribution level closer to the streaming source than the requesting network peer until a number of content sub-streams have been downloaded by the requesting network peer from which the requested data content can be formed. The present invention further relates to a method of requesting data content in a P2P network and a peer device.

摘要： A method of managing a network is described. The network comprises a set of user equipment, UEs. The method comprises: establishing, by the set of UEs, a Proximity Services, ProSe, group comprising the set of UEs; groupcasting, by the set of UEs, to the established ProSe group; and managing, by the set of UEs, the established ProSe group at a ProSe application layer, AL, optionally in coordination with a ProSe Application Server, AS. Establishing the ProSe group comprises providing a group identifier to the set of UEs by the ProSe AL. Each UE performs a group discovery using the group identifier by exchanging application discovery messages over a PC5 reference point between the UEs of the set.

摘要： A topology control system includes a sensing module, a data processing module, a data judgment module, a communication module and a central module. The sensing module collects data of surrounding nodes and transmits it to the data processing module for caching. The data processing module selects a cluster head of the current node according to the data in the cache and then transmits it to the data judgment module. The data judgment module checks the rationality of the cluster head and if the selection is reasonable feeds back the result to the data processing module. The communication module monitors the data sent by the data processing module and is responsible for wireless transmission of cluster head information to the central module. The central module collects the data of all nodes in the network and transmits the results to a client. It can be used for topology control of an ad-hoc network composed of fast-moving vehicles such as automobiles, ships, unmanned aerial vehicles (UAV). Selecting a cluster head involves classifying nodes according to an attraction matrix of the network and calculating an optimal transmission power of each node and whether the topology meets a connectivity requirement.

摘要： The invention relates to methods and devices of distributing data content in a live streaming peer-to-peer (P2P) network. In a first aspect of the present invention a method is provided of distributing data content in a P2P live streaming network comprising a plurality of peers and a streaming source periodically producing segments representing the data content to be distributed, wherein a group of the peers are assigned to download the data content from the streaming source and to distribute the downloaded data content to remaining peers in the P2P network. The method comprises making requests, from a first peer comprised in the group, for a current segment produced by the streaming source, the requests being made at a rate higher than a rate with which the segments are produced by the streaming source. Further, the method comprises announcing, if the first peer is the peer in the group being the first to download the current segment, that the current segment has been downloaded, wherein the network peers can download the current segment from said first peer; or else downloading the current segment from a second peer in the group being the first to download the current segment, which second peer announces the download of the current segment on the P2P network.

摘要：本发明涉及一种区块链网络拓扑动态建立和数据传输优化方法，用于解决区块链网络的数据传输效率低的问题。首先设计了可信值函数计算区块链节点的可信值，综合考虑节点的可信值和节点之间的数据传输时间构建树型拓扑。之后基于树型拓扑设计转发路径选择策略，以最小并发传输时间为目标，建立每个节点关于其邻居节点转发顺序的转发路径表。根据节点的加入行为、节点的离开行为、节点的可信值变化和节点之间的权值变化情况，设计了拓扑动态优化策略局部调整拓扑结构。本发明采用转发路径选择策略可以加快节点的数据转发，使用拓扑动态优化策略能够降低节点状态变化对拓扑调整的影响，有效缩短数据传输时间并减少额外开销。

摘要：本申请公开了一种分布式系统中主节点选取方法、装置及介质，包括：获取控制权限以作为临时主节点执行处理任务，以保证分布式系统在主节点宕机后能够正常运行；并通过判断阈值时间内执行处理任务过程中产生的错误消息数量是否大于第一数量阈值，判断当前节点是否为高性能节点；若大于阈值，则表明当前节点性能不足，则将控制权限移交至从节点，以便于从节点成为临时主节点；若小于阈值，则表明当前节点为高性能节点，则确定临时主节点为分布式系统的主节点。在本申请所提供的方案中，将控制权限主动移交至下一个临时节点并不断重复该操作，直到高性能节点成为主节点为止，在这一过程中不存在主节点宕机的情况，防止主节点频繁宕机影响系统运行。
