Abstract

The invention discloses an establishment method for a wireless mobile sensor network for monitoring an event. The method comprises the steps that S10, in an initial phase, static sensor nodes and mobile sensor nodes are randomly deployed in an event monitoring area and a sink node broadcasts and collects the position information of the static sensor nodes in the area; S20, in a data monitoring phase, the static sensor nodes monitor that events occur around; S30, mobile nodes are selected, the sink node receives a forwarding instruction and calculates that N mobile sensors are required for passing data back to the sink node from a request node according to the distance between the sink node and a forwarding request static node, and the sink node decides a fan-shaped start broadcast angle alpha towards the direction of the request node and collects the position information of the mobile sensors in the broadcast area; and S40, nodes are moved, through utilization of a Hungary algorithm, the N mobile sensors are matched on N candidate points, so the moving cost is minimum.

Description

technical field [0001] The invention belongs to the technical field of wireless sensing, relates to a wireless mobile sensing network, in particular to a construction method of a wireless mobile sensing network for monitoring events. Background technique [0002] The mobility of wireless mobile sensor networks is very important and has received widespread attention. In most studies, the use of mobile sensor nodes to assist in data transmission has been proven to prolong the life cycle of the entire network, but the current research does not consider the power balance of sensors. The present invention proposes an event data transmission mechanism for wireless mobile sensor networks. Lightweight data is directly transmitted from static sensor nodes to sink nodes, and heavyweight data uses linear regression to find candidate points on the linear regression line, making mobile The sensor assists heavyweight data transmission, and the moving distance is the least, forming a most...
