Abstract

The invention discloses a method and a device for planning the itinerary of a mobile agent, which relates to the technical field of wireless sensor network, reduces the energy consumption of the WSN (Wireless Sensor Network) network and prolongs the service life of the WSN network. The method comprises the following steps: if the accumulated value of the information gain is not larger than the threshold value of the information gain, determining the candidate position of a target object at the next time; judging whether the distance between the position of the node of the host sensor in which the mobile agent is located at present and the candidate position is larger than a first threshold value; if the distance is not larger than the first threshold value, un-moving the mobile agent; and if the distance is larger than the first threshold value, selecting the node of a target sensor from the nodes of the neighbors sensors of the host sensor in which the mobile agent is located, and moving the mobile agent to the node of the target sensor. The embodiment of the invention is mainly applied to the process of planning the itinerary of the mobile agent in target tracking scenes.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a method and device for planning a trip of a mobile agent. Background technique [0002] WSN (Wireless Sensor Networks, wireless sensor network) is composed of a large number of sensor nodes distributed in a certain space. The sensor node can collect signals from target objects (such as vehicles, mobile terminals, and even movable objects such as animals) in its coverage area, and perform data communication with other sensor nodes to obtain information about the target object. Realize the positioning and tracking of target objects. [0003] At present, when realizing the positioning and tracking of target objects, a calculation method based on mobile agents can be used to process the information collected by sensor nodes. The mobile agent can choose the running place and time by itself, interrupt the current execution according to the specific situation, and when moving to an...
