异构无线自组网中多尺度资源分配及公平性研究

Resource allocation problem is an important issue in heterogeneous ad hoc network. Existing resource allocation model is not suitable for heterogeneous ad hoc network, which is composed of coexist multi-terminals, elastic or inelastic flows, and various applications. The resource allocation efficiency is very low in such a complex and heterogeneous environment. This project aims to build a multi-scale, multi-factor resource allocation framework for heterogeneous ad hoc network. The fairness model is integrated into the framework. Then, a multi-scale, multi-factor and heterogeneous resource allocation system is realized. The main research topics of this project include: (1) To construct a heterogeneous resource allocation algorithm, which can deal with both elastic and inelastic traffic; (2) To establish a multi-scale resource allocation framework, which gives all-round optimization of the algorithm from three aspects of the energy scale, the rate scale and the price scale; (3) To propose a new model of utility fairness, which can be integrated into the framework and leads to build a multi-scale, multi-factor and extensible resource allocation system. The establishment of the system will provide full system optimization from various aspects, which has a high theoretical value and practical prospect.

异构无线自组网中的资源分配问题是一个亟待解决的重要课题。现有的资源分配模型不适合异构Ad Hoc网络，在多终端并存、弹性与非弹性流量混合的复杂异构环境中，资源分配效率低下。本项目旨在构建多尺度、多因素的异构无线自组网资源分配框架，并在该框架中融合公平性模型，最终实现一种异构、多尺度、多因素、可扩展的资源分配系统。项目的主要研究内容包括：(1) 构建一种异构的Ad Hoc网络资源分配算法，来统一处理弹性与非弹性流量问题；(2) 建立多尺度的资源分配框架，从能量尺度、速率尺度、价格尺度三个方面对资源分配算法进行全方位优化；(3) 提出新的效用公平性模型，将之融合到多尺度资源分配框架中，实现异构、多尺度、多因素、可扩展的资源分配系统。该系统的建立将对异构Ad Hoc网络提供多视角的系统优化，具有很高的理论价值和应用前景。
