Embodiment Construction
[0035] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0036] The basic process of query routing is that when a user has a query request, the sink node converts the user's query request into an interest message, and forwards the interest message to the nodes in the target area of the query request through the routing channel independently established by the network. For a mobile wireless sensor network, if a node in the target area moves out of the area, the monitoring task for the interest message can be stopped directly, and when a node outside the target area moves into the area, the node needs to obtain and update it in time interest messages and start corresponding monitoring tasks. Research on a reasonable interest message update algorithm is helpful to reduce the update frequency of interest messages. Therefore, the present invention provides a method and device for updating interest me...

The invention relates to a method and device for updating interest messages of movable nodes of a wireless sensor network, and belongs to the technical field of wireless sensor networks. The method comprises the steps that firstly, whether sensing areas of the movable nodes in the moving process overlap with sensing areas of fixed nodes or not is judged; then, when the sensing areas of the movable nodes overlap with the sensing areas of the fixed nodes, the similarities between the movable nodes, with the sensing areas overlapping with those of the fixed nodes, and the fixed nodes are calculated; finally, when the similarities are larger than a set threshold value, the interest messages are updated, and messages of the movable nodes are updated to be messages of the fixed nodes. By means of the process, the frequency of updating the interest messages can be greatly reduced, node energy consumption can be greatly reduced, and then the life cycle of the wireless sensor network can be prolonged.
Description
technical field [0001] The invention relates to a method and device for updating an interest message of a wireless sensor network mobile node, and belongs to the technical field of wireless sensor networks. Background technique [0002] The wireless sensor network is a network system composed of a large number of cheap micro sensor nodes deployed in the monitoring area in a self-organizing and multi-hop manner. The sensor nodes cooperate to perceive, collect and process the information of the monitoring objects in the network coverage area, and sent to observers. Wireless sensor networks do not require any fixed network support, and have the characteristics of rapid deployment, strong invulnerability, and long working life cycle, and have broad application prospects. Most of the initial research on wireless sensor networks is based on the assumption that the nodes are stationary. However, with the continuous expansion of the application field of wireless sensor networks, mo...
