This paper introduces Muclouds, a parallel simulation framework for simulating large-scale cloud computing systems. Muclouds improves the simulation performance for these large systems, such that the simulation time can be minimized. To achieve this goal, in this paper we propose a novel technique named stage and partition (SAP). SAP is based on the(More)
While scaling law results on the performance of mobile ad hoc networks (MANETs) have been extensively reported in literature, the exact performance of such networks, particularly their real achievable performance under practical network constraints, is still largely unexplored. As one step toward practical performance study for MANETs, this paper considers(More)
Transparent computing devices nowadays may be deployed in mobile ad hoc networks (MANETs), whose information theory is still lacking. As the first step towards learning MANETs for this paradigm, we propose 2HR-fτ, a simple algorithm that extends the traditional two-hop relay algorithms with deliver delay constraints. Extensive simulations are(More)
The real achievable performance of mobile ad hoc networks (MANETs), in particular the performance of such networks under practical constraints, is still largely unknown by now. As a step forward in this direction, this paper focuses on a MANET where a maximum allowed delivery delay is imposed to each packet and examines the impact of such delivery delay(More)
Device-to-device (D2D) content sharing holds great promise to alleviate the growing strain on cellular networks, as it offloads popular content data onto direct peer-to-peer links. However, it is still largely unexplored how content sharing could benefit from utilizing multi-hop rather than conventional single-hop D2D communications. As a step towards this(More)
