Embodiment Construction

[0012] On the basis of the improved GAF ​​wireless network topology control algorithm, the present invention adds opportunistic routing algorithm, a reliable and efficient routing method, and effectively combines them according to the characteristics of the two algorithms to form an energy efficient, A cross-layer protocol with high reliability and data forwarding efficiency.

[0013] The grid clustering-based opportunistic routing protocol for wireless sensor networks proposed in the present invention first needs to use a grid clustering method similar to the GAF algorithm to cluster the network, for example, use the GAF algorithm to divide the network into the following It is a grid with a radius, and a coordinate system is established based on the coordinate origin, and a coordinate value is marked for each grid. Each node can know the coordinate value of the grid it is in according to its own position information and the position information of the coordinate origin. Eac...

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network protocols, and in particular relates to an opportunistic routing method based on grid clustering in a wireless sensor network. In this method, the whole network area is divided into clusters in the form of a virtual grid by using the location information of the nodes first, and then the data packets are sent from the source node to the destination node through each cluster head node by means of opportunistic routing. Background technique [0002] Wireless sensor network is an emerging technical field that integrates microelectronics technology, wireless communication technology, and computer technology that has emerged in recent years. It has very broad application prospects in the fields of environment, medical treatment, and military affairs. Its development and application will give It has a profound impact on all aspects of human life and production. Although the large-scale c...
