  • Candidate selection algorithms in opportunistic routing based on distance progress 

    Darehshoorzadeh, Amir; Cerdà Alabern, Llorenç; Pla Boscà, Vicent (2015-01-01)
    Article
    Open Access
    Opportunistic routing (OR) is a new class of routing protocols that selects the next-hop forwarder on-the-fly. In contrast to traditionally routing, OR does not select a single node as the next-hop forwarder, but a set of ...
