Providing differentiated Quality of Service (QoS) over unreliable wireless channels is an important challenge for supporting several future applications. We analyze a model that has been proposed to describe the QoS requirements by four criteria: traffic ...

Wireless sensor networks (WSNs) form a unique class of ad hoc networks consisting of heterogeneous but highly resource-constrained devices that can sense their environment and report sensed data to designated nodes in the network. We present a holistic ...

In this talk we study the issue of cross-layer design for rate control in multihop wireless networks. We have developed an optimal cross-layered rate control scheme that jointly computes both the rate allocation and the stabilizing schedule that controls ...

In order to create secure and dependable systems and information intelligence, it is a major challenge to determine the security level of the network. This security level depends on a number of dynamically changing factors including emerging of new vulnerabilities ...

The Internet offers a host of high-quality research material in computer science---and, unfortunately, some very low quality resources as well. As part of learning the research process, students should be taught to critically evaluate the quality of ...

Vendors have started releasing the first products certified as complying with the IEEE's fast, long-range mobile WiMax standard. Proponents hope mobile WiMax will compete with cellular, Wi-Fi, and last-mile Internet-access technologies

Dynamic data replication improves data accessibility in mobile ad hoc networks. In our previous works, we proposed few methods to manage locations of replicas and efficiently forward access requests to the locations. In this paper, we extend these methods ...

As service providers move more applications to their IP/MPLS (Multiple Protocol Label Switching [1]) backbone networks, rapid restoration upon failure becomes more and more crucial. Recently MPLS fast reroute has attracted lots of attention as it was ...

A review of Mobile Applications: Architecture, Design, and Development by Valentino Lee, Heather Schneider, and Robbie Schell.

This dissertation investigates two research problems to protect wireless network topology and routing: (1) designing protocols with configurable overhead to defend against wormhole attacks; (2) designing an intruder identification mechanism ...

This paper presents an analysis of the control overhead involved in clustering and routing for one-hop clustered mobile ad hoc networks. Previous work on the analysis of control overhead incurred by clustering algorithms focused mainly on the derivation ...

In this work, we discuss some resource optimization problems in wireless and optical networks. In chapter 1, we consider Minimum Strongly Connected Dominating and Absorbent Set (MSCDAS) problem in a heterogeneous wireless ad-hoc network, where nodes ...

The existing security schemes are not applicable to ad hoc networks perfectly because ad hoc networks have some inherent security vulnerabilities and stringent resource constraints. This paper suggests using CPK as the security mechanisms of ad hoc networks ...

In the last years, wireless sensor networks have been proposed for their deployment in underwater environments where a lot of applications like aquiculture, pollution monitoring and offshore exploration would benefit from this technology. Despite having ...

This paper is motivated by the estimation problem and active safety design for ITS. We investigate the performance of model-based estimation over a multi-access network and emphasizes on asymptotic time-averaged MSE while using error-dependent transmission ...

With available data rates for mobile devices constantly increasing, services such as video broadcast and multicast are becoming feasible. A new standard called Multimedia Broadcast Multicast Services (MBMS) is being developed by 3GPP to enable new class ...

In conventional egress network access control (NAC) based on access control lists (ACLs), modifying the ACLs is a heavy task for administrators. To enable configuration without a large amount of administrators' effort, we introduce capabilities to egress ...

The aim of this work is to evaluate the risk of an external attack to the network of our Department in the University. Thus, this work wants to complement the results in [M. Benini, S. Sicari, A mathematical framework for risk assessment, in: H. Labiod, ...
