Dynamic Adaptive Wireless Networks with Autonomous Robot Nodes

Multihop无线功能将使自主节点在计划外环境和配置中能够进行通信和协调。与此同时，无线信道面临着动态运行条件、自主供电节点的功率限制以及高级行为与低级信道特性（例如，增加的同步通信将显著降低信道特性）之间复杂的相互作用的挑战。研究的主要目标是开发、测试和表征可扩展的、应用驱动的、使用异构通信移动节点集合的无线网络服务的算法。其中一些节点将是自主的（机器人），因为它们的运动将不受人类控制。其他的将是便携式的，因此，使他们依赖于人类的运输。虽然工作的重点是移动节点，但也包括网络上的非移动计算机。它强调大多数（虽然不是全部）移动节点将具有适度的传感、计算和通信资源。整个集合是传感器网络的一个例子。这项工作背后的主要科学动机是设计健壮、高效和可扩展的算法。研究人员假设，依赖于本地交互的分布式算法具有许多引人注目的特征，从而产生了这些特性。在协调携带一些传感器的自主移动节点的问题和在网络中指导信息流从源(s)到接收(s)的算法之间存在显著的重叠。这两套算法都将经过精心设计，以提高鲁棒性、效率和可扩展性。

The Multihop wireless capabilities will enable communication and coordination among autonomous nodes in unplanned environments and configurations. At the same time wireless channels present challenges of dynamic operating conditions, power constraints for autonomously-powered nodes, and complicating interactions between high level behavior and lower level channel characteristics (e.g. , increased synchronized communication will significantly degrade channel characteristics). The major goal of the research is the development, testing and characterization of algorithms for scalable, application driven, wireless network services using a heterogeneous collection of communicating mobile nodes. Some of these nodes will be autonomous (robots) in that their movements will not be human controlled. The others will be portable thus, making them dependent on humans for transportation. While the focus of the work is on the mobile nodes, include immobile computers on the network as well. It emphasize that most (though not all)of the mobile nodes will have modest sensing, computational and communication resources. The collection as a whole is an example of a sensor network. The chief scientific motivation behind the work is the design of robust, efficient and scalable algorithms. The researchers hypothesize that distributed algorithms that rely on local interactions have many compelling characteristics, resulting in these properties. There is significant overlap between the problems of coordinating the autonomous mobile nodes that carry some of the sensors and the algorithms that direct the f ow of information from source(s) to sink(s) in the network. Both setsof algorithms will be carefully designed to improve robustness, effciency and scalability.
