机会通信广泛用于延迟容忍网络、车载自组织网络（VANET）、灾难疏散指导、移动广告等中传播消息。它取决于移动实体（代理）彼此相遇的比率，因为它们在遇到其他实体时会交换消息。为了提高消息传播的效率，除了直接消息传递之外，诸如缓存之类的间接消息传递被认为是有用的。在本文中，我们引入了一种基于信息素的缓存，将每个节点定位在方形网格图中，以提高机会通信的消息传播效率。我们还使用 Lévy 步行运动模式对其进行测量，以阐明缓存技术的影响。
Opportunistic communication is widely used to diffuse messages in delay-tolerant networks, vehicular ad hoc networks~(VANETs), disaster evacuation guidance, mobile advertising, etc. It depends on the ratio that mobile entities~(agents) encounter one another because they exchange messages when they come across others. To improve the efficiency of message dissemination, indirect messaging such as caching is considered to be useful in addition to direct messaging. In this paper, we introduce a pheromone-based caching located each node in a square grid graph to improve the efficiency of message dissemination with opportunistic communication. We also measure it with Lévy walk movement pattern to clarify the impact of the caching technique.
