机会网络由于其固有的特点引起了研究人员的关注，包括长延迟、低数据速率和间歇性连接。人们已经对机会网络进行了广泛的研究，包括体系结构和路由。然而，很少有研究人员研究机会网络中的TCP性能，特别是在使用传染病路由的情况下。在本文中，我们首先评估了在带有传染病路由的机会网络中的TCP的性能。结果表明，机会网络中的传染病路由由于多拷贝数据包过多而降低了TCP的性能，从而消耗了有限的资源。针对上述问题，提出了一种基于TCP和传染病路由的跨层设计方案ACK-EPI。ACK-EPI可以避免已经发送的分组在网络中再次转发。仿真结果表明，ACK-EPI在机会网络中的性能优于传染病路由。
Opportunistic networks have attracted attention from researchers because of their inherent characteristics, including long latency, low data rate, and intermittent connectivity. Extensive research has been conducted on opportunistic networks, including the architecture and routing. However, few researchers have investigated the performance of TCP in opportunistic networks, especially when Epidemic Routing is used. In this paper, we first evaluate the performance of TCP in opportunistic networks with Epidemic Routing. Our results show that the Epidemic Routing in opportunistic networks degrades the performance of TCP due to too many multicopy data packets and in turn consume limited resource. Then a cross-layer design based on TCP and Epidemic Routing, named ACK-EPI is proposed to solve the above problem. ACK-EPI can avoid the packets that have already been delivered being forwarded again in the network. The simulation results show that ACK-EPI outperforms the Epidemic Routing in opportunistic networks.
