无线自组织网络是一种很有前途的网络技术，可以为用户提供随时随地的互联网接入。为了应对无线自组网的资源约束，数据缓存被广泛应用于有效降低数据访问成本。本文提出了一种高效的数据缓存算法，该算法利用无线通信的窃听特性来提高缓存性能。由于无线链路的广播性质，即使节点不是预期的目标，分组也可以被发射机传输范围内的节点窃听。我们提出的算法利用窃听的信息，包括数据请求和数据回复，来优化缓存布局和缓存发现。据我们所知，这是第一个在数据缓存中考虑无线通信的窃听特性的工作。仿真结果表明，与一个典型算法和一个朴素的监听算法相比，该算法可以显著降低消息开销和访问时延。
Wireless ad hoc network is a promising networking technology to provide users with Internet access anywhere anytime. To cope with resource constraints of wireless ad hoc networks, data caching is widely used to efficiently reduce data access cost. In this paper, we propose an efficient data caching algorithm which makes use of the overhearing property of wireless communication to improve caching performance. Due to the broadcast nature of wireless links, a packet can be overheard by a node within the transmission range of the transmitter, even if the node is not the intended target. Our proposed algorithm explores the overheard information, including data request and data reply, to optimize cache placement and cache discovery. To the best of our knowledge, this is the first work that considers the overhearing property of wireless communications in data caching. The simulation results show that, compared with one representative algorithm and a naive overhearing algorithm, our proposed algorithm can significantly reduce both message cost and access delay.
