Efficient Edge Cache Collaboration Transmission Strategy of Opportunistic Social Network in Trusted Community

With the continuous development of 5G network technology, the amount of data has surged. Network data transmission technology needs improvement. To ensure the reliable transmission of data, reduce network congestion and network energy consumption, the paper proposed an effective edge cache collaboration routing strategy of opportunistic social networks in the trust community, namely the edge collaboration cache trust community routing algorithm (ECTC). The algorithm proposes that the nodes are used to carry information through the cache. Based on the node trust degree, the efficient trust relay node is identified. Build a trusted network based on the trust degree of nodes. Divide local trust community modules into clusters to realize efficient community retrieval. Under the concept of edge nodes, trust nodes are found in the trust community. Edge caches cooperate to share transmitted data, reducing backbone network congestion. The data update efficiency is greatly improved. Through edge nodes in trust community cooperation and communication, efficient data packet delivery is realized, thereby improving the community trust network's routing performance. The simulation experiment results show that the edge collaboration cache trust community routing algorithm (ECTC) can significantly improve delivery effectiveness and reduce network overhead.
