Majority of the existing Delay Tolerant Network (DTN) routing protocols, attempt to minimize one of the popular DTN
routing indices, i.e. message delay, forwarding count and storage. However, for many DTN applications such as
distributing commercial content, targeting the best performance for one index and compromising the others is
insufficient. A more practical solution would be to strike a balance between multiple of these indices. Gain
Dissemination Protocol (GDP) is one of the protocols which targets this aim by introducing a gain concept which tries
reach a maximum gain of delivery by keeping the balance between the value achieved via delivering the packet to the
destination and the forwarding cost involved with that. In this paper, we focus on characterizing the GDP protocol in the
scope of mobility. We also propose an upper bound for gain in multicast routing problem, i.e. the Union of Unicast
Benchmark (UUB) and compare the performance of a few DTN routing protocols with the former. This eventually
reveals the performance scope of a potential gain-aware DTN dissemination protocol.
