Network coding was found to be useful for ad hoc wireless multicast in disruptive channel and connectivity conditions. In heterogeneous networks, comprising teams with different technical preparedness, it is possible that only the radios of the most advanced teams have sufficient resources to network encode/decode. In this case, an interesting solution is partial (hybrid) network coding - only a fraction of the nodes encodes, the balance simply forwarding the packets. Partial coding poses interesting problems and opportunities that require novel solutions. The first contribution of this paper is the control of redundant transmissions. The second contribution is the study performance loss caused by partial coding.
