The protocols and architectures of today's ad hoc networks are derivatives of those developed in the past for the Internet, which in turn date back to the ARPANET design in the 1960s. This is the wrong approach for mobile ad hoc networks (MANET), because they are very different than wired networks. In particular, many-to-many communication is intrinsic to MANETs, because of their decentralized peer-to-peer nature and the broadcast nature of wireless channels. In contrast, the protocol stacks used today are designed to avoid multiple access interference (MAI) to support one-to-one communication.This project proposes a blank-slate approach to the modeling and design of communication protocols for ad hoc networks and MANETs. The project will seek improvements on the order capacity of ad hoc networks by means of architectures and protocols for many-to-many communication enabled by the statistical multiplexing of wireless spectrum, processing, and storage resources in such networks. The project will re-examine commonly held notions about the way in which channel access and information transport should be accomplished when in-network storage and processing are affordable, thus making multi-packet reception (MPR) a viable approach. This project will provide fundamental advances to the understanding of (a) approaches that enable many-to-many communication in MANETs by exploiting processing and storage complexity in mobile nodes; (b) how to model communication protocols operating in MANETs; and (c) what are more meaningful fundamental limits for the dissemination of information over MANETs when many-to-many communication is allowed.

今天的自组织网络的协议和体系结构是过去为互联网开发的协议和体系结构的衍生物，而这些协议和体系结构又可以追溯到20世纪60年代的阿帕网设计。对于移动自组织网络（MANET）来说，这是错误的方法，因为它们与有线网络非常不同。特别是，由于其分散的点对点性质和无线信道的广播性质，多对多通信是manet固有的。相比之下，目前使用的协议栈旨在避免多址干扰（MAI），以支持一对一通信。本项目提出了一种用于自组织网络和manet的通信协议建模和设计的空白方法。该项目将通过无线频谱、处理和存储资源的统计多路复用实现多对多通信的架构和协议，寻求改进自组织网络的订单容量。该项目将重新审查关于当网络内存储和处理负担得起时信道访问和信息传输应以何种方式完成的普遍观念，从而使多包接收成为一种可行的方法。该项目将为以下方面的理解提供基础进展：(a)通过利用移动节点的处理和存储复杂性，实现manet中多对多通信的方法；(b)如何对在manet中运行的通信协议进行建模；(c)当允许多对多通信时，在manet上传播信息的更有意义的基本限制是什么。
