Cooperation willingness aware caching mechanism towards opportunistic network

摘要

The message in the opportunistic network is transmitted in the form of storage-carry-forward. Designing a reasonable cache management mechanism is of great significance to improve the network performance of the opportunistic network. An opportunity network cache management mechanism with collaborative willingness aware is proposed. The ability to cache messages by nodes is estimated by modeling and analyzing the generation and extinction process of node messages. It estimates the cooperative willingness of the nodes, and finally stores the redundant messages to the nodes with higher cooperative willingness, so as to improve the cache utilization of the nodes and improve the performance of the network.
