Title:
無線ネットワークにおけるデータ・パケットの時空間注釈付け
Document Type and Number:
Japanese Patent JP5856626
Kind Code:
B2
Abstract:
Techniques for annotating data packets with time and/or location information in wireless networks are provided. In one aspect, a method for processing information streams produced by end-computing devices that are transmitted over a wireless network having at least one network element is provided. The method includes the following steps. Data packets which originate from the end-computing devices and are received by the network element are inspected for spatiotemporal metadata. Spatiotemporal metadata is inserted into the data packets and the data packets are transmitted if the step of inspecting the data packets reveals that the data packets are missing spatiotemporal metadata. Otherwise the data packets are transmitted if the step of inspecting the data packets reveals that spatiotemporal metadata is already present in the data packets.
