Embodiment Construction

[0062] Aiming at the coverage maintenance problem of wireless sensor networks, especially for the coverage scheduling of redundantly deployed sensor networks, a coverage maintenance method for wireless sensor networks is proposed. Location information, a wireless sensor network coverage maintenance method for energy balance through the cooperation between adjacent nodes. The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0063] A method for maintaining coverage of a wireless sensor network, comprising the following steps:

[0064] 1) After the wireless sensor network is initialized, its running time is divided into several rounds, and each round is followed by the coverage control phase and the state stabilization phase, and the next round is performed after one round is over;

[0065] 2) In one round, in the coverage control phase, K nodes are ele...

Abstract

The invention discloses a wireless sensor network coverage maintaining method. The method is based on a probability calculation method to carry out a node redundancy judgment without node position information required, and the wireless sensor network coverage maintaining method carries out an energy balance through collaboration between neighboring nodes. After initialization of a wireless sensor network, operating time is divided into a number of rounds, each round in order carries out a coverage control phase and a state steady phase, and one round is followed by a next round when the one round ends. In the invention, the probability calculation method is used to calculate the node redundancy and coverage quality; the probability calculation method is simple; the node position information is not required; the node precise position information is not relied on; the cost of network hardware is significantly reduced; and the great application value is realized.

Description

technical field [0001] The invention belongs to the technical field of network resource optimization, and relates to a method for maintaining coverage of a wireless sensor network. Background technique [0002] The coverage scheduling problem of wireless sensor networks can be regarded as under the condition that the energy of sensor network nodes, wireless network communication bandwidth, network computing power and other resources are generally limited, using the redundancy of nodes, heuristic algorithms can be used to make nodes in different states Switch between nodes, turn off nodes in turn under the premise of satisfying the quality of service (QoS), and finally optimize the allocation of various resources in the network, balance the energy consumption of nodes, and prolong the life of the network. Aiming at the sensing characteristics of randomly deployed wireless sensor networks in the actual environment, how to perform efficient coverage scheduling is a basic but ur...
