This project investigates effective and resource efficient establishment of connectivity among disjoint wireless sensor network (WSN) segments. The segments can belong to a structurally damaged network caused by the failure of multiple sensor nodes. In addition, the segments can simply be standalone WSNs that are normally operated by different agencies and are to be federated to serve a common application. The objectives of this project are to develop novel solutions for various aspects and contexts of the federation problems, to create a prototype for validation and to share the results/experience with application designers. The technical approaches consider the availability of resources such as mobile sensors, mobile and static gateways and their count. Both optimal and heuristic solutions for repositioning of mobile sensors and placement of mobile gateways are studied to establish connectivity as well as achieving some desired performance (i.e., QoS). Finally, the results are validated via a real test-bed consisting of sensors and mobile robots. This project will boost the effectiveness of many civil and scientific applications. Example of such applications include crisis management, where existing WSNs may suffer an extensive loss of nodes due to fire, flooding, debris, etc., or when the services of networks owned or controlled by different parties or agencies need to be aggregated to assess in search-and-rescue. The results are made available in various forms including archival publications, tutorials and web-based resources. The project is enriching the curricula at UMBC and SIUC through hands-on projects and attracting K-12 students via prototype demonstrations.

该项目研究在不相交的无线传感器网络 (WSN) 段之间建立有效且资源高效的连接。这些网段可能属于由多个传感器节点故障引起的结构性损坏的网络。此外，这些部分可以只是独立的 WSN，通常由不同的机构运营，并且可以联合起来为通用应用程序提供服务。该项目的目标是针对联合问题的各个方面和背景开发新颖的解决方案，创建用于验证的原型并与应用程序设计者分享结果/经验。技术方法考虑了移动传感器、移动和静态网关及其数量等资源的可用性。研究了用于重新定位移动传感器和放置移动网关的最佳解决方案和启发式解决方案，以建立连接并实现一些所需的性能（即 QoS）。最后，结果通过由传感器和移动机器人组成的真实测试台进行验证。该项目将提高许多民用和科学应用的有效性。此类应用的示例包括危机管理，其中现有的 WSN 可能会因火灾、洪水、碎片等而遭受大量节点损失，或者需要聚合不同方或机构拥有或控制的网络服务以评估搜救。结果以多种形式提供，包括档案出版物、教程和基于网络的资源。该项目通过实践项目丰富了 UMBC 和 SIUC 的课程，并通过原型演示吸引了 K-12 学生。
