Ad Hoc网络中的主动路由:应该有多少个中继?节点应该使用什么速率?

Opportunistic Routing in Ad Hoc Networks: How many relays should there be? What rate should nodes use?

Joseph Blomer, Nihar Jindal

摘要:

启发式路由是一种多跳路由方案,它允许选择最佳的立即可用的中继。在盲机会路由协议中,发射机在不知道周围节点的情况下进行盲广播,两个基本的设计参数是节点传输概率和传输频谱效率。在本文中,这些参数的选择,以最大限度地提高端到端的性能,其特征在于产品的发射机密度,跳距和速率。由于上述问题的棘手性,一个近似函数被证明是相当准确的检查。我们的研究结果表明,上述设计参数应如何选择的基础上固有的系统参数,如路径损耗指数和噪声水平。

英文摘要:

Opportunistic routing is a multi-hop routing scheme which allows for selection of the best immediately available relay. In blind opportunistic routing protocols, where transmitters blindly broadcast without knowledge of the surrounding nodes, two fundamental design parameters are the node transmission probability and the transmission spectral efficiency. In this paper these parameters are selected to maximize end-to-end performance, characterized by the product of transmitter density, hop distance and rate. Due to the intractability of the problem as stated, an approximation function is examined which proves reasonably accurate. Our results show how the above design parameters should be selected based on inherent system parameters such as the path loss exponent and the noise level.
