本文提出了第一个全面的容量延迟权衡研究随机无线Ad Hoc网络下的所有信息传播模式（单播，组播，广播，任播）时，节点操作与多包接收（MPR）或单包接收（SPR）的能力。我们的结果表明，对于单播，增加容量需要SPR的额外延迟，类似于[1]中的结果，而MPR不会招致惩罚，即，我们可以同时增加容量和减少延迟的MPR。对于多播，对于SPR和MPR两者没有折衷。然而，当使用MPR时，对于广播可以观察到类似的折衷，而与SPR没有折衷。
This paper presents the first comprehensive capacity-delay tradeoff study for random wireless ad hoc networks under all information dissemination modalities (unicast, multicast, broadcast, anycast) when nodes operate either with multi-packet reception (MPR) or single-packet reception (SPR) capabilities. Our results demonstrate that for unicast, increasing capacity requires additional delay for SPR similar to the results in [1] while MPR incurs no penalty, i.e., we can increase capacity and decrease delay simultaneously for MPR. For multicast, there is no tradeoff for both SPR and MPR. However, similar tradeoff can be observed for broadcast when MPR is used while there is no tradeoff with SPR.
