Embodiment Construction

[0033] The present invention will be further elaborated below in combination with specific embodiments.

[0034] Network Settings and Division

[0035] Randomly deploy n nodes in the two-dimensional plane, and each node has enough neighbor nodes for communication. The communication radius of the nodes is r, and they know their own geographical location information and the geographical location information of the destination node. In order to select nodes in a suitable area for relay forwarding, we first divide the network area. Set the area of ​​the network area as S, and X and Y are the length and width respectively. R is the side length of a divided area, and satisfies mod(X,R)=mod(Y,R)=0, such as figure 1 . The nodes in each divided area know the position information of the four vertices in the divided area. When a node needs to forward data, it will establish a forwarding area for data forwarding.

Abstract

The invention discloses a geographic information opportunity routing protocol of a wireless sensor network. According to a strategy, network zones are divided; and path guide points are determined through utilization of geographic information of each node and a sink node, and the most suitable relay node is selected, thereby achieving purposes of a relatively short path, relatively few forwarding hop count or relatively low transmission time delay. Moreover, in order to reduce the network energy consumption, a sleep wakeup mechanism and a geographic information opportunity routing strategy are combined; idle nodes are arranged to sleep; the network separation resulting from the fact that the nodes are excessively consumed to die is avoided; and the service life of a network is prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a geographic information opportunistic routing protocol for wireless sensor networks. Background technique [0002] Wireless sensor network (WSN, wireless sensor networks) is a wireless multi-hop network formed by sensor nodes deployed in the monitoring area that cannot be recharged. In a wireless sensor network, nodes collect information and form data, which is transmitted to the destination node through a multi-hop transmission mechanism. During data transmission, nodes use pre-established routing strategies for transmission, so the formulation of routing strategies is crucial to the performance of all aspects of the entire network. However, during the working process of wireless sensor networks, the network topology structure is constantly changing due to emergencies, and the traditional routing strategy cannot adapt to this working mode well. good solution....
