The complexity and dynamics of Border Gateway Protocol (BGP), the only inter-domain routing protocol available for the Internet, is driving the need for efficient, scalable, realistic and meaningful network simulations. To properly simulate the behavior of BGP as currently deployed, one requires both a realistic topology and a realistic model of BGP. Although a large number of topology generators...
This paper concerns infinitesimal perturbation analysis (IPA) for fluid queues with finite buffers, where input fluid in excess of buffer capacity is turned away and considered lost. In particular, it considers the loss-volume (and hence average loss rate) performance measure with respect to the buffer sizes. Most previous results pertained to open- loop systems, but recently there has been a mounting...
Mobile ad-hoc networks (MANETs) are used for emergency situations like disaster-relief, military applications, and emergency medical situations. These applications make MANETs attractive targets for cyberattacks and make the development of counter-measures paramount. The study of worm behavior is critical to the design of effective counter measures in MANET environments. This paper studies the behavior...
Although it is commonly assumed that the use of topology control can improve the throughput capacity of wireless networks, analytical results on this topic are sometimes contradictory and no comprehensive simulation study has been attempted. In this paper, we report the results of a packet-level simulation-based study of topology control in CSMA/CA networks. The results demonstrate significant throughput...
