Network coding
In the network coding problem, there are k commodities each with an associated message Mi, a set of sources that know Mi and a set of sinks that request Mi. Each edge in the graph may transmit any function of the messages. These functions define a network coding solution. We explore three topics …

Network coding for anonymous broadcast
This thesis explores the use of network coding for anonymous broadcast. Network coding, the technique of transmitting or storing mixtures of messages rather than individual messages, can provide anonymity with its mixing nature, efficiently disseminate content in multicast and broadcast networks, …

Applying network coding to TCP
… of a new TCP-like protocol, CTCP, that uses network coding to provide better network use of the network bandwidth in a wireless environment. CTCP provides the same guarantees as TCP whilst providing significant enhancements to previous TCP implementations, such as permitting multipath packet …

Evolutionary approaches toward practical network coding
… numerous studies showing various benefits of network coding. However, in order to have network coding widely deployed in real networks, it is also important to show that the amount of overhead incurred by network coding can be kept minimal and eventually be outweighed by the benefits network …

Network coding for delay challenged environments
… a fundamental problem of data communication and networks, a problem that is not usually addressed in classical coding, information or networking theory. We focus on the general problem of delay challenged networks. This delay challenge may be related to different reasons, for example, 1) large …

Network coding for robust wireless networks
Wireless networks and communications promise to allow improved access to services and information, ubiquitous connectivity, and mobility. However, current wireless networks are not well-equipped to meet the high bandwidth and strict delay requirements of future applications. Wireless networks …

Network coding for speedup in switches
Network coding, which allows mixing of data at intermediate network nodes, is known to increase the throughput of networks. In particular, it is known that linear network coding in a crossbar switch can sustain traffic patterns that cannot be served if network coding were not allowed. Thus, network …

Networking from a network coding perspective
Network coding generalizes network operation beyond traditional routing, or store-and-forward, approaches, allowing for mathematical operations across data streams within a network. This thesis considers a number of theoretical and practical networking issues from network coding perspectives. We …

Deterministic network coding by matrix completion
Network coding is a new field of research that addresses problems of transmitting data through networks. Multicast problems are an important class of network coding problems where there is a single sender and all data must be transmitted to a set of receivers. In this thesis, we present a new …

Secure network coding with a cost criterion
Network coding is a viable alterative to traditional routing methods that are being used in current data networks as it offers many advantages, including higher throughput rates and lower network costs. Although research has been conducted with regards to the cost and security issues of network …

Completion Delay Minimization for Instantly Decodable Network Coding
Instantly Decodable Network Coding (IDNC) is a subclass of opportunistic network coding that has numerous desirable properties for a wide spectrum of applications, namely its faster decoding delay, simpler coding and decoding processes, and no decoding buffer requirements. Nonetheless, IDNC suffers …

Optimal forwarding in wireless networks: opportunistic network coding
In wireless networks, unintended nodes in the vicinity of the sender and receiver, potentially causing interference to their own communications, can generally overhear transmissions. Much of the related research has considered this as a nuisance and resulted in various proposals for overcoming the …

Optimized Network Coding for Wireline and Aref Networks
With the aim of understanding network coding in wireless scenarios, we investigate multicasting in Aref networks. These networks do not capture interference, but they do incorporate deterministic broadcasting. We characterize the multicast capacity of Aref networks, the achievability of which is …

Energy-aware network coding circuit and system design
Network Coding (NC) has been shown to provide several advantages in communication networks in terms of throughput, data robustness and security. However, its applicability to networks with resource constrained nodes, like Body Area Networks (BANs), has been questioned due to its complexity …

Performance of random network coding for data dissemination
Network coding is an alternative to traditional store-and-forward routing and is known to be necessary to achieve network capacity. It has also been shown randomized network coding is robust, and far outperforms store-and-forward for multicast. While much focus has been on the data rates achievable …

Low-latency network coding for streaming video multicast
Network coding has been successfully employed to increase throughput for data transfers. However, coding inherently introduces packet inter-dependencies and adds decoding delays which increase latency. This makes it difficult to apply network coding to real-time video streaming where packets have …
