Next generation communication systems will integrate mobile ad hoc networks, wireless mesh networks, and all-IP cellular networks into hybrid networks. Key features of these systems are the multiplicity of access technologies and the diversity of nodes to facilitate always best connected (ABC) communication and pervasive computing. The survivability of hybrid networks is of paramount importance to homeland security, where the networks must fulfill their missions in a timely manner even in the presence of failures or attacks. This project aims to (1) develop hybrid routing protocols where portions of the same route span both infrastructure components and multi-hop wireless components of different networking characteristics, (2) integrate control with computing and communication to harness mobility and control trajectory to achieve eventual connectivity, (3) design hybrid transport mechanisms that cope with asymmetry, and (4) develop utility-based congestion control algorithms that maximize the aggregate transport utility over wireless networks. The project is investigating integrated solutions and pursuing cross-layer design, and will yield theory, algorithms, and protocols that help enhance capacity and survivability of hybrid networks. In addition, the educational activities of the project are to integrate control with computing and communication into mobile wireless networking curricula to foster the next phase of the information technology revolution, and to develop tools such as protocol animations to help comprehend protocol concepts, simulation exercises to help learn a complex simulator, and methodology for simulation and performance evaluation. The results will be disseminated and will be of value to both the educational community and industry.

下一代通信系统将把移动自组织网络、无线网状网络和全ip蜂窝网络集成到混合网络中。这些系统的主要特点是接入技术的多样性和节点的多样性，以促进始终最佳连接（ABC）通信和普适计算。混合网络的生存能力对国土安全至关重要，即使在存在故障或攻击的情况下，网络也必须及时完成其任务。该项目旨在(1)开发混合路由协议，其中同一路由的部分跨越不同网络特征的基础设施组件和多跳无线组件；(2)将控制与计算和通信集成，以利用移动性和控制轨迹来实现最终的连接；(3)设计应对不对称的混合传输机制。(4)开发基于效用的拥塞控制算法，使无线网络上的总传输效用最大化。该项目正在研究集成解决方案并追求跨层设计，并将产生有助于增强混合网络容量和生存能力的理论、算法和协议。此外，该项目的教育活动是将控制与计算和通信整合到移动无线网络课程中，以促进信息技术革命的下一阶段，并开发协议动画等工具，以帮助理解协议概念，模拟练习，以帮助学习复杂的模拟器，以及模拟和性能评估的方法。研究结果将得到传播，对教育界和工业界都有价值。
