Embodiment Construction

[0016] 1. Select the appropriate anchor node:

[0017] The stage of selecting a suitable anchor node is divided into two steps, the first step is the automatic selection stage, and the second step is the sink control stage. sequence in time. In the first step, the sink automatically selects the anchor node with the strongest signal-to-noise ratio to communicate with. When the sink moves to a certain distance, the second step, the sink control phase, is taken. In this stage, the sink informs the current communication anchor node to stop forwarding data, and then the sink selects the appropriate anchor node for communication

[0018] Automatic selection stage: the sink node broadcasts an inquiry message and then selects the anchor node V with the strongest signal-to-noise ratio to communicate with it. When the sink node moves farther than H, the sink selects another anchor node V n as a communication node. At this time, if only V and V are considered as in the ALS protocol ...

Abstract

The invention discloses a geographic position information-based mobile sink routing method, which comprises steps of determining a proper anchor node and establishing a data transmission path. A mobile sink routing protocol of the invention can effectively support the mobile sink and effectively balance the energy consumption of the network; the anchor node through which the mobile sink can determine the position of a source node can be added in the entire network; and the source node can transmit the data to the anchor node by using the geographic information-based routing protocol and then transmit the data from the anchor node to the sink node.

Description

technical field [0001] The invention relates to a routing method of a routing protocol of a mobile sink sensor network based on geographic location information, which belongs to the improvement of the routing method of a wireless sensor network. Background technique [0002] Wireless multimedia sensor network is a new type of sensor network that introduces audio, video, image and other multimedia information perception functions on the basis of traditional wireless sensor networks. Its nodes are generally equipped with CMOS cameras, miniature microphones and other devices with simple environmental data collection functions. Sensors, which are generally deployed in an unattended environment to complete specified tasks autonomously, are a sensitive non-infrastructure network. Compared with traditional WSNs that only have simple environmental data collection functions, WMSNs can perceive multimedia information such as audio, video, and images with rich information, and can real...
