摘要翻译：
在这项工作中，我们解决了一个全新的情况，即无线ad hoc网络中移动节点（玩家）的相遇问题。我们假设玩家拥有的唯一信息是其他玩家的接收信号强度(RSS)测量值，并且没有集中通信。每个节点有一个不同的频带，它们试图以分散的方式彼此相遇。我们考虑允许玩家在一个网格中沿四个正交方向移动的情况。然后，我们使用多臂强盗方法，在玩家使用RSS测量所做的每一步移动结束时给予奖励。考虑到我们有一个对抗性的设置，我们提出了不同的算法来解决会议问题。我们从考虑两个玩家开始，然后将多人问题看作多个两人问题，将工作扩展到多人问题。在整个论文中，我们构造了会议时间和相关概念的数学界，并在最后对仿真结果进行了评估。

英文摘要：
In this work, we address a completely novel case which is the meeting problem of mobile nodes (players) in a wireless ad hoc network. We assume that the only information players have is the received signal strength (RSS) measurements of other players and there is no centralized communication. Each node has a different frequency band and they try to meet with each other in a decentralized manner. We consider the case where players are allowed to move in four orthogonal directions in a grid. Then, we use multi-armed bandit approach to give rewards in the end of every move that players do using RSS measurements. Taking into account that we have an adversarial setting, we propose different algorithms to solve the meeting problem. We start with considering two players and then extend the work to multiplayer by considering multiplayer problem as multiple two player problems. Throughout the paper, we construct mathematical bounds on meeting times and related concepts and evaluate the simulation results in the end.
