HBCU-UP RIA: Analytical Studies of Multihop Wireless Networks with the Log-normal Shadowing Model

该项目将在一个考虑了重要边界效应的真实阴影模型下对多跳无线网络进行分析研究。该项目将调查每个节点在阴影模型下确保网络几乎必然地渐近连接所需的临界传输功率，并探索网络连接概率与网络没有孤立节点的概率之间的关系。在实际的多跳无线网络中，我们将研究在阴影模型下无线电不规则性对网络连通性和无线电干扰的影响。该项目的最终目标是为潘恩学院的计算机科学研究和教育做出重大改进，并增加非裔美国本科生对计算机科学研究的参与。移动和无线设备的迅速普及为无线网络领域的理论研究提供了极好的机会。对数正态阴影模型是一种得到广泛应用的逼真的电波传播模型。在任何实际的多跳无线网络中，都必须考虑重要的边界效应。在这种包含边界效应的阴影模型下，人们对实际多跳无线网络的连通性以及无线电不规则性对连通性和干扰的影响知之甚少。这项研究的结果将在吞吐量、虚拟骨干网、拓扑控制、路由协议、信息论和网络等领域产生重要意义。多跳无线网络有望在解决我们的家园安全、保护基础设施、监测生物圈内的条件或诊断和治疗疾病等问题方面发挥关键作用。

This project will conduct analytical studies on multi-hop wireless networks under a realistic shadowing model with an important boundary effect taken into consideration. The project will investigate the critical transmission power required for each node to ensure that the network is connected asymptotically almost surely under a shadowing model, and explore the relation between the probability that the network is connected and the probability that the network has no isolated nodes. The impact of radio irregularity on network connectivity and radio interference in practical multihop wireless networks under the shadowing model will be examined. The ultimate goal of this project is to make significant improvements for research and education in computer science at Paine College and increase the participation of African American undergraduate students in computer science research.The rapid proliferation of mobile and wireless devices provides an excellent opportunity for theoretic research in the wireless networking area. The log-normal shadowing model is a realistic radio propagation model which has been widely used. The important boundary effect must be taken into consideration in any practical multihop wireless networks. Under such a shadowing model with the boundary effect included, little is known about connectivity of practical multihop wireless networks and the impact of radio irregularity on connectivity and interference. The results of this research will be of interest in areas such as throughput capacity, virtual backbone, topology control, routing protocols, information theory and networking. Multihop wireless networks are expected to play a key role in solving problems such as securing our homeland, protecting the infrastructure, monitoring conditions in the biosphere, or in the diagnosis and treatment of illnesses.
