Broadcast encryption (BE) is a cryptographic primitive that allows a broadcaster to encrypt digital content to a privileged set of users and in this way prevent revoked users from accessing the content. In BE schemes, a group of users, called traitors may leak their keys and enable an adversary to receive the content. Such malicious users can be detected through traitor tracing (TT) schemes. Th...

Mobile and static nodes in battlefields or within the vicinity of disaster areas may not depend on fixed infrastructure for communication. To rapidly provide the required communication between the nodes in such environments, a Mobile Ad hoc Network (MANET) is the only available platform. With no fixed infrastructure, the efficient use of MANETs resources is highly crucial for the successful com...

Global Positioning System (GPS) Technology allows precise determination of location, velocity, direction, and time. The price of GPS receivers is falling rapidly and the applications are growing. PCMCIA receivers that can be connected to any notebook personal computers are available for $300-400 to end consumers. The main goal of this study was to survey current applications of GPS to distribut...

Wireless sensor networks consist of small nodes which are capable of sensing, computation, and communication. The initial goal of a sensing system is to detect the events of interest. In this project, we study decentralized detection in sensor networks. First, we will review the classical decentralized detection framework, in which a set of spatially distributed sensor nodes receives informatio...

Mobile Ad hoc networks (MANETs), mesh networks, and multi-hop sensor networks are instances of multi-hop wireless networks where nodes cooperate to forward traffic among each other. Such networks are important whenever infrastructure is unavailable or expensive, and quick deployment is desired. They play an important role in many existing and emerging applications in the military, industry, res...

Vehicular ad hoc networks (VANETs) enable the timely broadcast dissemination of event-driven messages to interested vehicles. Especially when dealing with broadcast communication, data dissemination protocols must achieve a high degree of scalability due to frequent deviations in the network density. In dense networks, suppression techniques are designed to prevent the so-called broadcast storm...
