This collaborative project concentrates on four main research thrusts: (i) a detailed study to statistically characterize protocol interaction, (ii) a scalable agent-based service to provide all nodes with state information, (iii) a Media Access Control (MAC) protocol utilizing smart antennas, and, (iv) the usage of inverse optimization as a framework for characterizing algorithmic protocol interaction. The focus on the network and MAC layer protocol interaction in wireless mobile ad-hoc networks is in the context of a generalized location service that provides a mechanism to obtain the current position of a mobile node by using smart antennas. This service, called Network Environment Wireless State service (NEWS) service, is generalized to obtain other aspects of node state, such as its local traffic characteristics, velocity, and energy usage, in addition to its location; it provides current "news," i.e., state, to the rest of the system. Such a service can improve the performance of protocols and provide information for emerging services based on location and other state information. This project also aims at identifying the impact of protocol interaction, both algorithmic and statistical, first in an implementation of a NEWS service wherein different network and MAC solutions are mixed and matched. Furthermore, this project defines a hierarchical agent-based NEWS service that uses local traffic conditions and node density to spawn (slay) agents to operate in a recursively defined grid area. The design of this protocol complements a MAC layer solution that can take advantage of location and the ability to control transmit power level to directionally transmit within the appropriate grid level. Finally, this project will use a framework based on inverse optimization to decide when to spawn agents at the network layer to obtain successful transmissions at the MAC layer, i.e., to optimize the interlayer interaction.

这个合作项目集中在四个主要的研究重点：（一）一个详细的研究，以统计特性的协议交互，（二）一个可扩展的基于代理的服务，提供所有节点的状态信息，（三）一个媒体访问控制（MAC）协议，利用智能天线，以及，（四）使用逆优化作为一个框架，用于表征算法协议交互。在无线移动的ad-hoc网络中的网络和MAC层协议交互的重点是在广义的位置服务的上下文中，该位置服务提供了一种机制，通过使用智能天线来获得移动的节点的当前位置。该服务被称为网络环境无线状态服务（NEWS）服务，其被推广以获得节点状态的其他方面，诸如其本地业务特性、速度和能量使用，以及其位置;其提供当前“新闻”，即，国家，到系统的其他部分。这种服务可以提高协议的性能，并基于位置和其他状态信息为新兴服务提供信息。该项目还旨在确定协议交互的影响，包括算法和统计，首先在实现一个新闻服务，其中不同的网络和MAC解决方案的混合和匹配。此外，该项目定义了一个层次化的基于代理的新闻服务，使用本地的交通状况和节点密度来产生（杀死）代理在递归定义的网格区域中操作。该协议的设计补充了MAC层解决方案，该解决方案可以利用位置和控制发射功率电平的能力来在适当的网格级别内定向发射。最后，该项目将使用基于逆优化的框架来决定何时在网络层产生代理以在MAC层获得成功传输，即，以优化层间相互作用。
