Introduction

Otnes, Roald; Asterjadhi, Alfred; Casari, Paolo; Goetz , Michael; Husøy, Thor; Nissen, Ivor; Rimstad, Knut; van Walree, Paul; Zorzi, Michele

Pages: 1 –4

[Digital underwater communications are becoming increasingly important, with numerous applications emerging in environmental monitoring, exploration of the oceans, and military missions. Until the mid-nineties, the research was focused on hardware and on communication transmitters and receivers...

Topics Bordering the Physical Layer

Otnes, Roald; Asterjadhi, Alfred; Casari, Paolo; Goetz , Michael; Husøy, Thor; Nissen, Ivor; Rimstad, Knut; van Walree, Paul; Zorzi, Michele

Pages: 5 –18

[The actual need for time synchronization within an underwater acoustic network is not always present. It can be argued that given a network with an operation time of hours or a few days, any standard equipment will have a clock drift that is negligible given most applications and network...

Medium Access Control

Otnes, Roald; Asterjadhi, Alfred; Casari, Paolo; Goetz , Michael; Husøy, Thor; Nissen, Ivor; Rimstad, Knut; van Walree, Paul; Zorzi, Michele

Pages: 19 –48

[Medium access control (MAC), also known as multiple access control, is a sublayer of the data link layer and manages access to the medium. In underwater networks, MAC protocols orchestrate the access to the acoustic communication channel. Without MAC, collisions of unsolicited modem signals may...

Logical Link Layer Topics

Otnes, Roald; Asterjadhi, Alfred; Casari, Paolo; Goetz , Michael; Husøy, Thor; Nissen, Ivor; Rimstad, Knut; van Walree, Paul; Zorzi, Michele

Pages: 49 –61

[In this chapter, we describe methods to ensure reliable information delivery to higher layers at the sink(s), while keeping overhead, retransmissions, and discarded information as low as possible. The basic mechanism to achieve this is typically ARQ (automatic repeat request), but many variants...

Routing

Otnes, Roald; Asterjadhi, Alfred; Casari, Paolo; Goetz , Michael; Husøy, Thor; Nissen, Ivor; Rimstad, Knut; van Walree, Paul; Zorzi, Michele

Pages: 63 –83

[Routing is a fundamental network primitive in any wireless network. Given typical transmit power constraints, it is very unlikely that all nodes in a network are within the transmit range of one another. For this reason, many messages may have to be relayed towards their destination through...
