We consider a grid network where nodes contain small buffers. A packet that faces a crowded buffer in its route will get extra latency and may be dropped. In this paper, we propose a novel flow control protocol called RFCC for grid networks. RFCC tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

Linear network coding provides a new communication diagram to significantly increase the network capacity by allowing the relay nodes to encode the incoming messages. However, this communication diagram is fragile to communication errors and pollution attacks. How to combat errors while maintaining the network efficiency is a challenging research problem. In this dissertation, we study how to c...

In this work we analyze performance of network coding focusing on two specific network coding schemes: XOR and random linear network coding. We have simulated different topologies and traffic patterns in order to provide better understanding of network coding behavior and its possible bottlenecks. As a part of our performance evaluation we consider also computational complexity of coding and de...

This paper studies the practicality of network coding to facilitate cooperative content distribution. Network coding is a new data transmission technique which allows any nodes in a network to encode and distribute data. It is a good solution offering reliability and efficiency in distributing content, but network coding has not been widely used because of its dubious performance gains and codi...

Network coding has been widely acknowledged as an effective approach to improve the throughput of wireless mesh networks (WMNs) and a few network coding based routing algorithms for wireless mesh networks have been proposed. This paper investigates the state of the art of network coding based routing algorithms for WMNs that exploits network coding in routing algorithms. In addition, the taxono...

In order to enhance multicast communication, it is important to investigate effects of network coding which can be a typical application of active network. In this paper, we study the feasibility of network coding based multicast architecture from performance aspect. We first show that the network coding based multicast has not only high transmission capacity with the max-flow, which is an orig...
