Design and Implementation of Network Coding in NextGen systems

Abstract

Network coding is a technique in which, instead of simply relaying the packets of information, the intermediate nodes of a network combine incoming input streams for transmission. These 'combinations' are subsequently decoded at the destination using algebraic methods. We aim to implement the concept of Network Coding (NC) in three MISO topologies, using USRP Software-Defined Radio testbeds, and measure the performance of each topology against its non-NC counterpart using experimental results on Bit Error rates (BER), throughput and goodput. Moreover, we aim to realize, whether network coding provides the theoretical advantage of throughput and energy efficiency and in which conditions it outperforms non-network coding operations.
