Hybrid network mobile node coverage detection method and node deployment selection method

Abstract

The invention provides a hybrid network mobile node deployment selection method which comprises the following steps: a mobile node starts from a starting point, a basic behavior is firstly selected to carry out deployment detection, a static node is deployed after the completion of implementing one basic behavior, and the mobile point initiatively obtains the distance difference of an obstacle in the horizontal direction in the deployment process; if no obstacle exists in the horizontal direction, the deployment detection is continuously performed; after the completion of implementing one basic behavior, the mobile node uses and implements a vertical basic behavior to carry out static node deployment, and after completion, a deployment detection process of a basic behavior in the next direction is started; the mobile node judges whether a point location close to an obstacle area in the X direction belongs to an effective point location of a deployed static node or not by using a 3 node plus 1 distance method, the deployment of the static node is performed after the predetermined conditions are met, otherwise, the deployment is not carried out. The node deployment selection method provided by the invention has the benefit that the deployment number of the static node can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of control of mobile nodes in a hybrid network, in particular to a method for detecting coverage of a mobile node in a hybrid network and a node deployment selection method. Background technique [0002] Node deployment is one of the basic issues in the research field of wireless sensor networks. According to the allowable deployment methods and application requirements, an appropriate amount of nodes should be placed in the appropriate position in the monitoring area. [0003] The hybrid sensor network is a new mobile node based on the wireless sensor network, relying on the controllability and maneuverability of the mobile node to perform enhanced functions such as coverage detection, vulnerability supplementary coverage, and node deployment. Node deployment is the first step to ensure that a hybrid sensor network maintains high-efficiency monitoring performance. [0004] The mobile nodes and the existing...

Problems solved by technology

[0006] Network coverage is one of the basic problems faced by distributed information collection and data processing in hybrid networks. Sensor nodes may be randomly distributed in the configuration area. How to achieve full coverage of the entire monitoring area is very important. At present, many studies are mostly focused on monitoring areas. Static nodes are scattered at random. During orderly deployment, more static nodes are deployed in key areas to basically meet the coverage requirements. This brings challenges to system cost and overall system power consumption.
