Scalable and Efficient Key Agreement Protocols for Secure Multicast Communication in MANETs
(2002)
In this paper protocols for group key distribution are compared and evaluated from the point of view of Mobile Ad Hoc Networks (MANETs). A MANET is a collection of wireless mobile nodes, communicating among themselves over ...
Broadcast Scheduling for Push Broadcast Systems with Arbitrary Cost Functions
(2007)
In this report the problem of broadcast scheduling in Push broadcast systems is studied. We introduce an optimization approach that leads to well justified policies for Push broadcast systems with generalized cost functions. ...
HYBRID NETWORKS WITH A SPACE SEGMENT - TOPOLOGY DESIGN AND SECURITY ISSUES
(2005)
In this paper we investigate a hybrid network topology that is suitable for supporting interplanetary communications. We define an architecture comprised of a network of sensor nodes on a remote planetary surface, connected ...
A Dynamic Optimization Approach to the Scheduling Problem in Satellite and Wireless Broadcast Systems
(2002)
The continuous growth in the demand for access to information andthe increasing number of users of the information delivery systemshave sparked the need for highly scalable systems with moreefficient usage of the bandwidth. ...
Load balancing in multi-beam satellite systems
(2004)
We propose an approach to optimize resource sharing and in a multi-beam broadband satellite system that supports both unicast and multicast flows. We show that in this architecture, the load on every spot-beam queue could ...
Jitter Analysis of CBR Streams in Multimedia Networks
(2003)
The performance of real time applications such as video andvoice streams relies on packet delay jitter. Large delay jittercauses buffer overflow or underflow at the receiver end and theuser encounters interrupts. The delay ...
Fault-Tolerant Extension of Hypercube Algorithm for Efficient, Robust Group Communications in MANETs
(2005)
Securing multicast communications in Mobile Ad Hoc Networks (MANETs) has become one of the most challenging research directions in the areas of wireless networking and security. MANETs are emerging as the desired environment ...
Negotiating Access Control Policies Between Autonomous Domains
(2002)
Autonomous policy domains often need to share resources to accomplish a common task. To do this they must negotiate a common access control policy to the shared resources. We use mathematical techniques from game theory ...
A Parallel Virtual Queue Structure for Active Queue Management
(2003)
The performance of the Adaptive RED scheme is susceptible to bursty web traffic. In this paper a parallel virtual queue structure is proposed for active queue management at the bottleneck router. Real time connections such ...
A Parallel Virtual Queue Structure for Active Queue Management
(2003)
The Adaptive RED proposed by Feng is shown to have small packetdelay and queue length variation for long-life TCP traffic suchas FTP connection with a large file size. However, a greatportion of Internet traffic is short-life ...
