Information Transmission Probability and Cache Management Method in Opportunistic Networks

Abstract EN

In real network environment, nodes may acquire the communication destination during data transmission and find a suitable neighbor node to perform effective data classification transmission.

This is similar to finding certain transmission targets during data transmission with mobile devices.

However, the node cache space in networks is limited, and waiting for the destination node can also cause end-to-end delay.

To improve the transmission environment, this study established Data Transmission Probability and Cache Management method.

According to selection of high meeting probability node, cache space is reconstructed by node.

It is good for nodes to improve delivery ratio and reduce delay.

Through experiments and the comparison of opportunistic network algorithms, this method improves the cache utilization rate of nodes, reduces data transmission delay, and improves the overall network efficiency.
