Frame model for cooperative context awareness

Abstract

The invention relates to a frame model for cooperative context awareness. The frame model comprises equipment nodes, an awareness node acquiring context information, and a center node or fusion node transmitting instruction information to the equipment node, wherein the center node is a computer or a mobile phone; the equipment node is wirelessly connected with the center node through a Zigbee network, an intelligent grouping and resource sharing (IGRS) network, a universal radio frequency (RF) network, a universal plug and play (UPnP) network or a digital living network alliance (DLNA) network; the awareness node is wirelessly connected with the center node through the Zigbee network, the IGRS network, the universal RF network, the UPnP network or the DLNA network; the equipment nodes are wirelessly connected through the Zigbee network, the IGRS network, the universal RF network, the UPnP network or the DLNA network; and a cooperative awareness mode among the awareness node, the center node and the equipment nodes comprises a related-task-based inter-node cooperative awareness mode, a same-task-based inter-node cooperative awareness mode and a fusion mode combining the related-task-based inter-node cooperative awareness mode and the same-task-based inter-node cooperative awareness mode. Awareness reliability and accuracy are improved, a node utilization rate is increased, and the computing and storage pressure of the center node is alleviated.

Description

technical field [0001] The invention relates to a framework model of cooperative context awareness, which belongs to the technical field of wireless sensor networks. Background technique [0002] With the development of ubiquitous computing, wireless sensor networks, and digitalization of information equipment, various information equipment emphasizes the adaptation and integration of the environment, which requires perception technology. Compared with the traditional digital environment, the perceived digital environment can provide users with more and more humanized services, mainly including multimedia services, remote monitoring and medical services, and comfortable environment experience services. These services require a certain amount of network transmission bandwidth, and devices require high computing and storage capabilities, but not all devices have the same powerful capabilities. caused difficulties. [0003] In 1991, Mark Weiser of the PARC Research Center of ...

AI Technical Summary

Problems solved by technology

This means that information can only exist in a single device, and the devices do not have collaborative perception capabilities, and cannot share each other's perception information, so that it is impossible for each device to form an organic whole and coordinate work at the system level

So far, no general collaborative context-aware model can meet the perception needs of smart spaces, such as smart homes, smart classrooms, smart factories, etc.
