Abstract—In wireless networks, we need to allocate spectrum efficiently.One challenge is that the spectrum usage requests often come in an online fashion. The second challenge is that the secondary users in a cognitive radio network are often selfish and prefer to maximize their own benefits. In this paper, we address these two challenges by proposing

Abstract: Mission-driven sensor networks usually have special lifetime requirements. However, the density of the sensors may not be large enough to satisfy the coverage requirement while meeting the lifetime constraint at the same time. Sometimes, coverage has to be traded for network lifetime. In this paper, we study how to schedule sensors to maximize their

Abstract: Traffic measurements provide critical input for a wide range of network management applications, including traffic engineering, accounting, and security analysis. Existing measurement tools collect traffic statistics based on some predetermined, inflexible concept of “flows.” They do not have sufficient built-in intelligence to understand the application requirements or adapt to the traffic conditions. Consequently, they

Abstract—This paper develops parametric methods to detect network anomalies using only aggregate traffic statistics, in contrast to other works requiring flow separation, even when the anomaly is a small fraction of the total traffic. By adopting simple statistical models for anomalous and background traffic in the time domain, one can estimate model parameters in real

Abstract:         In wireless sensor networks, asynchronous sleep–wake scheduling protocols can be used to significantly reduce energy consumption without incurring the communication overhead for clock synchronization needed for synchronous sleep–wake scheduling protocols. However, these savings could come at a significant cost in delay performance. Recently, researchers have attempted to exploit the inherent broadcast nature of

Abstract: Placement of regenerators in optical networks has attracted the attention of recent research works in optical networks .In this problem, we are given a network with an underlying topology of a graph G and with a set of requests that correspond to paths In G. There is a need to put a regenerator every

Abstract—Reservation-based (as opposed to contention-based) channel access in WLANs provides predictable and deterministic transmission and is therefore able to provide timeliness guarantees for wireless and embedded real-time applications. Also, reservation-based channel access is energy-efficient since a wireless adaptor is powered on only during its exclusive channel access times. While scheduling for Quality of Service at

ABSTRACT While peer-to-peer networks are mainly used to locate unique resources across the Internet, new interesting deployment scenarios are emerging. Particularly, some applications are proposing the creation of overlays for the localization of services based on equivalent servants. This paper explores the possible overlay architectures that can be adopted to provide such services, showing how

Infrastructure as a Service (IaaS) cloud computing has revolutionized the way we think of acquiring resources by in- traducing a simple change: allowing users to lease computational resources from the cloud provider’s data center for a short time by deploying virtual machines (VMs) on these re- sources. This new model raises new challenges in the
