Abstract
Source-destination network coded cooperation (SDNCC), an extension of adaptive network coded cooperation (ANCC), which uses network coding and matches code-on-graph with network-on-graph, is proposed for wireless ad-hoc networks that comprise a collection of terminals communicating wirelessly to a common destination. In SDNCC, the destination broadcasts which terminal packets to be selected in the relay phase, which generates low-density generator-matrix (LDGM) codes with unequal error protection at cost of 1 bit per terminal. Additionally, the outage probability of SDNCC is evaluated and closed-form expression is derived for infinity networks. Furthermore, simulation results show that SDNCC achieves 4dB performance improvement over ANCC at frame error ratio (FER) of 3 × 10^-5.
