摘要： This invention generally relates to Low-power and Lossy Wireless Networks. The proposed solution takes advantage of the fact that retry mechanism and back-off mechanism are already present in trickle-based algorithms. This way, it is possible to disable the equivalent features present at the MAC level which are the main causes of the large maxima of the fluctuating end-to-end delay. Also, it has been done away with the additional waiting time which comes from the packet waiting in the buffer in the MAC. Therefore, it has been provided a real-time layer with a limited size buffer able to allocate a deadline to a multicast packet and to select packets for transmission or rejection on the basis of the packet deadline. This way, it is kept a tighter hold on the rejection and waiting of the packets.

摘要翻译：本发明一般涉及低功率和有损无线网络。所提出的解决方案利用了基于涓流算法的重试机制和退避机制已经存在的事实。这样，可以禁用存在于MAC级别的等效特征，这是波动的端到端延迟的最大值的主要原因。此外，已经完成了从MAC中缓冲区中等待的数据包的附加等待时间。因此，已经提供了具有有限大小的缓冲器的实时层，其能够为组播分组分配最后期限，并且基于分组截止时间选择用于传输或拒绝的分组。这样一来，对数据包的拒绝和等待就保持了更严格的限制。

摘要： A wireless network (252) has a mesh structure of wireless communication links between nodes (210, 220). The network enables an unsecured node (230) to join the network by exchanging joining messages with a configurator (200). The configurator (200) is arranged for determining network security states including an insecure state in which all nodes are in the unsecured mode and the network is open for joining nodes; a partially secure state in which at least one node (210, 220) is in the secured mode and the network is open for joining nodes; and a secure state in which the network is closed to nodes in the unsecured mode. The nodes detect the security state and adapt their operation to the detected security state of the network and the mode of the device. The adapted operation enables flexible security bootstrapping of the network.
