Network-Coded Multiple Access

Prioritization, security and relay selection in network coded multiple access relay networks

Wireless communication is undoubtedly one of the most significant advancements by the mankind for improving quality of life. Information is transmitted from one point to another via electromagnetic waves. After Shannon’s landmark paper “A Mathematical Theory of Communication” in 1948, significant advancements have occurred in providing reliable point to point wireless communication. With ever g...

Network-Coded Cooperation Analysis for Multiple Source – Multiple Relay Architectures

Distributed channel coding and network coding techniques are means employed to improve the performance of cooperative transmissions. This paper studies the BLER performance provided by a cooperative scheme that combines distributed channel coding and network coding for multiple sourcemultiple relay architectures, within which the number of available relays is smaller than the number of sources....

Iterative Receiver Techniques for Coded Multiple Access Communication Systems

Sensor Network with Multiple Mobile Access Points

We consider sensor networks with mobile access points where data at sensor nodes are collected by multiple mobile access points. Using throughput and energy efficiency as performance measures, we address the optimal coverage areas of and the cooperation among the mobile access points. We show that when the mobile access points do not cooperate in demodulation, disjoint coverage areas are optima...

Network Coded TCP (CTCP)

We introduce CTCP, a reliable transport protocol using network coding. CTCP is designed to incorporate TCP features such as congestion control and reliability while improving on TCP’s performance in lossy and/or dynamic networks. CTCP builds upon the ideas of TCP/NC introduced by Sundararajan et al. and uses network coding to provide robustness against losses. We provide an implementation of CT...
