A hybrid routing protocol for underwater acoustic networks [PDF]

open access: yes2018 17th Annual Mediterranean Ad Hoc Networking Workshop (Med-Hoc-Net), 2018
—This paper presents a new packet-forwarding mechanism for underwater acoustic networks. The solution, termed MPR-Light, combines the modus operandi of the Multi-Point Relay (MPR) protocol and of the Enhanced Flooding (EFlood), both described in [1]. MPR-Light aims at providing the ro-bustness of a flooding solution in the presence of unreliable and ...
