本文研究了移动的自组网中采用Grossglauser和Tse(2001)提出的两跳中继算法的渐近吞吐量和时延。我们假设节点是均匀分布在一个球体上,并考虑两个典型的移动模型:布朗移动模型(BMM),和随机路点移动模型(RWMM)。我们证明了对于由n个移动的节点组成的ad hoc网络,在BMM下的时延为O(log/sup 2/n//spl sigma//sup 2/(n)),在RWMM下的时延为O(spl Theta/(1/r(n)v(n)),其中/spl sigma//sup 2/(n)是BMM的方差参数,v(n)是RWMM下节点的平均速度,r(n)是节点的通信半径.
We study the asymptotic throughput capacity and delay in mobile ad hoc networks following the 2-hop relaying algorithm proposed by Grossglauser and Tse (2001). We assume the nodes to be uniformly distributed on a sphere, and consider two canonical mobility models: the Brownian mobility model (BMM), and the random way-point mobility model (RWMM). We show that for an ad hoc network formed by n mobile nodes the delay scales as O (log/sup 2/n//spl sigma//sup 2/(n)) under the BMM, and, /spl Theta/ (1/r(n)v(n)) under the RWMM, where /spl sigma//sup 2/(n) is the variance parameter of the BMM, v(n) is the average speed of nodes under the RWMM, and r(n) is the communication radius of the nodes.
