Mobility is central to various applications, from the classicalproblems of searching for a moving target and rescue mission inmilitary and disaster settings, to deploying mobile ad-hoc/sensornetworks for surveillance and data communication over hostileterrain and underwater. While the random mobility pattern of nodes inthese networks has been considered as the main source of uncertainty anddisruption of communication links, it can also facilitate reliable andpredictable performance, if properly controlled and actively exploited.Most existing approaches have taken advantage of nodes' mobility only aspassive vehicles for data forwarding upon contact by chance, with anover-simplifying assumption that every pair of nodes is making contactswith each other according to a Poisson process, which is recentlycontradicted by empirically observed non-Poisson nature with high degreeof heterogeneity in various mobile networks.The long-term goal of this research is to develop a unified methodologyfor efficient protocol design and control of nodes in heterogeneousmobile ad-hoc networks and delay/disruption-tolerant networks undernon-Poisson contacts. The goal further extends to the use of mobilenodes with controllable mobility that can autonomously exploit thechanging diversity. The broader impact of this research lies in itsinterdisciplinary nature in addressing the analysis and design ofalgorithms running on mobility with heterogeneous non-Poisson contacts,which is also central to other scientific areas such as epidemiology,foraging ecology and biology, all driven by contacts among livingorganisms. This tight relationship between mobile ad-hoc networksand various phenomena in nature will serve as a vivid example forundergraduate students at a freshmen level or even to general public.

移动性是各种应用的核心，从军事和灾难环境中搜索移动目标和救援任务的经典问题，到部署移动自组织/传感器网络以在敌对地形和水下进行监视和数据通信。虽然这些网络中节点的随机移动模式已被认为是通信链路不确定性和中断的主要来源，但如果适当控制和积极利用，它也可以促进可靠和可预测的性能。大多数现有方法仅将节点移动性作为被动利用偶然接触时进行数据转发的车辆，有一个过于简化的假设，即每对节点都根据泊松过程相互接触，这与最近根据经验观察到的非泊松性质相矛盾这项研究的长期目标是开发一种统一的方法，用于异构移动自组织网络和非泊松接触下的延迟/中断容忍网络中的节点的有效协议设计和控制。该目标进一步扩展到使用具有可控移动性的移动节点，这些移动节点可以自主地利用不断变化的多样性。这项研究更广泛的影响在于其跨学科性质，解决了具有异质非泊松接触的移动性算法的分析和设计问题，这也是流行病学、觅食生态学和生物学等其他科学领域的核心，所有这些领域都是由生物体之间的接触驱动的。移动自组织网络与自然界各种现象之间的这种紧密关系将为本科生乃至普通公众提供一个生动的例子。
