Error Control for Multicasting in Satellite and Hybrid Communication Networks
(2001)
A problem inherent in ARQ multicasting over a broadcast channel is thata retransmission typically benefits only a minority of destinationswhile all others wait unproductively. This results in poorthroughput to each receiving ...
Medium Access Control and Quality-of-Service Routing for Mobile Ad Hoc Networks
(2001)
A mobile ad hoc network is an autonomous system consisting solely of mobile terminals connected with wireless links. This type of network has received considerable interest in recent years due to its capability to be ...
A New Adaptive Aggregation Algorithm for Infinite Horizon Dynamic Programming
(2001)
Dynamic programming suffers the "curse of dimensionality" when it isemployed for complex control systems. State aggregation is used to solvethe problem and acceleratecomputation by looking for a sub-optimal policy. In this ...
Queue Dynamics of RED Gateways under Large Number of TCP Flows
(2001)
We consider a stochastic model of a RED gateway under competing TCP-likesources sharing the capacity. As the number of competing flows becomes large, the queue behavior of RED can be described by a two-dimensional recursion. ...
Approximate Receding Horizon Approach for Markov Decision Processes: Average Reward Case
(2001)
Building on the receding horizon approach by Hernandez-Lerma andLasserre in solving Markov decision processes (MDPs),this paper first analyzes the performance of the (approximate) receding horizon approach in terms of ...
Nonlinear Instabilities in TCP-RED
(2001)
This work introduces a discrete time model for a simplified TCP network with RED control. It is argued that by sampling the state space at certain instants, the dynamics of the system can be described explicitly as a ...
Efficient Resource Utilization through Carrier Grouping for Half-duplex communication in GSM-based MEO Mobile Satellite networks
(2001)
In the near future, existing terrestrial radio networks are envisioned to integrate with satellite systems to provide global coverage. In order to enable communication for both non-hand-held and hand-held User Terminals ...
Optimization Based Rate Control for Multipath Sessions
(2001)
In this paper, we consider the rate control problem for multipath sessionswith the objective ofmaximizing the total user (session) utility. This problem provides a frameworkin which flow control and routing are jointly ...
Update Propagation Strategies for Improving the Quality of Data on the Web
(2001)
Dynamically generated web pages are ubiquitous today but their high demand for resources creates a huge scalability problem at the servers. Traditional web caching is not able to solve this problem since it cannot provide ...
On System Designs of Distributed, Extensible Framework for Network Monitoring and Control
(2001)
In this paper, we present a distributed, extensible framework for supporting adaptive, dynamic network monitoring and control. We borrow the paradigm of management by delegation [8] and distribute some processing intelligence ...
