Opportunity routing algorithm based on network encoding in satellite network

Abstract

The invention relates to an opportunity routing algorithm based on network encoding in a satellite network. The opportunity routing algorithm comprises the following steps: S1, modeling the maximum average throughput of the satellite network, wherein modeling elements comprise a source node, a destination node, a relay node, a sending rate of an information source, a performance function of the average throughput, a credit rate, a data packet and a feedback encoding packet; S2, figuring out an optimal solution structure of the model by using the convex optimization theory; S3, compressing feedback information indicating that the data packet is received in a feedback encoding packet by using the encoding feedback technology, and meanwhile, locally maintaining a link state table in each node by using the encoding feedback technology, wherein the link state is the information of the node and an adjacent node and a measurement of the link, and the measurement comprises a Lagrange variable difference of the node and the adjacent node; S4, processing and determining to send a next hop node set of the current data packet and determining the size of the credit rate of each node in the set by the relay node by using an encoding feedback algorithm; and S5, confirming a data segment.

Benefits of technology

The technology described by this patented solves problems with current methods that use network codes for efficient communication between devices within an internet protocol (IP) connection system without overloading any resources or causing delays during signal transfer due to failures along specific links connecting different parts of the IP system together. This results in improved efficiency and reliability when transmitting signals across multiple networks connected via these connections.

Problems solved by technology

This patented technical problem addressed by these two methods described for improving wireless networking performance involves developing new techniques or combining them into one more effective way than just relying solely upon default route selection algorithms like Mobi_Reno.
