Embodiment Construction

[0048] Step 1). The monitoring area is divided into several square grid areas, and an anchor node with GPS is deployed in the center of each area;

[0049] Step 2). Deploy the wireless multimedia sensor network, and all nodes in the network communicate with the anchor node to obtain their own unique regional information;

[0050] Step 3). The network is divided into clusters, and each cluster elects a cluster head node to be responsible for communicating with the base station, and sets the remaining nodes to be idle;

[0051] Step 4). The cluster head node records the node number and area information of the nodes in the cluster;

[0052] Step 5). In each cluster except the cluster head node, select the calculation state nodes according to the selection strategy with the most remaining energy, calculate and process the target data in the monitored surrounding environment, and the remaining nodes directly execute the monitoring task collection as the monitoring state nodes sens...

Abstract

A wireless multimedia sensor network-based regional target tracking method is an application proposal based on the positioning by a wireless multimedia sensor network and is mainly used for solving the problems of node positioning and target tracking in a wireless multimedia network. In the method, a target tracking task is assigned to different nodes, and the nodes in different states and at different positions in the network cooperate to complete the target tracking task defined by a user. The invention also provides a corresponding method for detecting the regional target tracking. On the basis of a simple statistic instruction, the method can effectively detect the motion trace of a target monitored in the network in real time, avoid excessive network and node resource consumption caused by increasing network tracking precision based on a complex algorithm and ensure the objective accuracy, integrity and timeliness of the target tracking, thereby meeting the application needs of the wireless multimedia sensor network and further guaranteeing the safety of the wireless multimedia sensor network.
