Embodiment Construction
[0048] The invention is a wireless sensor network routing optimization method based on congestion control. The preferred embodiments are described in detail below in conjunction with the drawings. It should be emphasized that the following description is only exemplary, and is not intended to limit the scope of the present invention and its application.
[0049] The present invention overcomes the shortcomings of the existing wireless sensor network routing method, introduces the basic concepts and principles of hydrology, establishes a node queue model, and builds a link drop and flow radius function based on the geographic location of the node and the data packet service rate. The link flow rate assigns an appropriate routing probability to each path, thereby effectively optimizing the energy consumption of the entire network, and reducing the network delay and packet loss rate.
[0050] The present invention includes the following steps:
[0051] Step 1: Establish a link reducti...

The invention belongs to the technical field of wireless communication, and particularly relates to a congestion control based wireless sensor network routing optimization method. The method comprises the steps of establishing a link gradient function from each node to a prior neighbor node according to geographical location information of the nodes; constructing a node queue model, and establishing a flow radius function of each link according to the data packet service rate of the nodes; constructing a link flow rate model among the nodes according to the established link gradient function and the flow radius function; establishing a routing forward probability function by the nodes according to difference in each link flow rate so as to complete establishment of routing; and establishing a congestion detection function so as to carry out real-time detection on the congestion degree of a network, and carrying out local routing maintenance once node congestion occurs. According to the invention, the link gradient function is established through using basic conceptions and principles in hydrology for reference, thereby sufficiently realizing effectiveness of node energy consumption, enabling energy consumption of the whole network to be optimized, and having good real-time performance and reliability.
Description
Technical field [0001] The invention belongs to the field of wireless communication technology, and in particular relates to a method for optimizing wireless sensor network routing based on congestion control. Background technique [0002] Wireless sensor networks are currently widely used in fields such as environmental monitoring, military applications, road transportation, medical and health care due to their low cost, low power consumption, and self-organization. The routing protocol has always been the research hotspot of WSN. The traditional routing protocol mainly aims at extending the network life cycle according to the characteristics of WSN node energy limitation, such as LEACH, EEUC, etc. However, in certain scenarios, such as electricity consumption information collection, transmission line detection, etc., the nodes can be continuously powered by the line, and the energy continues. The previous routing algorithm may lead to unreasonable route selection and cause a wa...
