【摘要】 随着无线技术的快速发展，节点间的通信能力极大增强。传统的“存储—携带—转发”机制已广泛应用于分布式社交物联网中，节点通过该机制将消息传递给目标节点。由于现有的路由算法在复杂网络环境中的表现仍存在不足，因此如何优化并设计出更高效、可靠的路由算法，成为当前的研究热点。首先，本文介绍了社交物联网的基本架构及其路由算法的技术路线。其次，将社交物联网中的路由算法分为四类:经典路由算法、自私节点激励算法、改进转发效率的算法以及受其他学科启发的算法，并分别梳理每类路由算法的优缺点。最后，结合现有路由算法的局限性与面临的挑战，探讨未来可能的研究方向与发展趋势。更多还原

【Abstract】 With the rapid development of wireless technologies,the communication capability among network nodes has been greatly enhanced. The traditional “store – carry – forward” mechanism has been widely applied in distributed social Internet of Things(SIoT) networks,enabling nodes to transmit messages to target nodes. However,existing routing algorithms still face performance limitations in complex network environments. Therefore,designing more efficient and reliable routing algorithms has become a key research focus. This paper first introduces the basic architecture and technical routes of routing algorithms in the SIoT. Then,routing algorithms are categorized into four main types: classical routing algorithms,incentive-based algorithms for selfish nodes,algorithms for improving forwarding efficiency,and algorithms inspired by other disciplines. The strengths and weaknesses of each type are analyzed in detail. Finally,the paper discusses the limitations and challenges of current routing algorithms and explores potential research directions and development trends for the future.更多还原
