Adaptive Multimode Medium Access Control for Underwater Acoustic Networks

Shiraz Shahabudeen;Mandar Chitre;Mehul Motani

IEEE Journal of Oceanic Engineering
Year: 2014 | Volume: 39, Issue: 3 | Journal Article |
Cited by: Papers (17)
Standards such as 802.11 have played a key role in the success of terrestrial radio wireless communications. Similar standardization will be needed in underwater acoustic networks (UANs) of the future. One of the important aspects of standardization is UAN medium access control (MAC). Since no single protocol can satisfy the diverse requirements of a general UAN MAC, we explore the possibility of ...Show More

Analysis of a High-Performance MAC Protocol for Underwater Acoustic Networks

Shiraz Shahabudeen;Mehul Motani;Mandar Chitre

IEEE Journal of Oceanic Engineering
Year: 2014 | Volume: 39, Issue: 1 | Journal Article |
Cited by: Papers (25)
Multiple access with collision avoidance (MACA) is a popular medium-access control (MAC) protocol for terrestrial networks (e.g., 802.11). Underwater acoustic networks (UANs) differ from terrestrial networks as they are characterized by long propagation delays and higher data loss. Most of the published analysis for MACA in terrestrial networks ignores these factors, and, therefore, cannot be dire...Show More

Throughput of Networks With Large Propagation Delays

Mandar Chitre;Mehul Motani;Shiraz Shahabudeen

IEEE Journal of Oceanic Engineering
Year: 2012 | Volume: 37, Issue: 4 | Journal Article |
Cited by: Papers (74)
Propagation delays in underwater acoustic networks can be large as compared to the packet size. Conventional medium-access control (MAC) protocol design for such networks focuses on mitigation of the impact of propagation delay. Most proposed protocols to date achieve, at best, a throughput similar to that of the zero propagation delay scenario. In this paper, we systematically explore the possibi...Show More

MAC protocols that exploit propagation delay in underwater networks

Shiraz Shahabudeen;Mandar Chitre;Mehul Motani

OCEANS'11 MTS/IEEE KONA
Year: 2011 | Conference Paper |
Cited by: Papers (15)
This paper discusses novel medium access control (MAC) protocols for underwater acoustic networks that utilize propagation delay to increase the network throughput. Traditional MAC design considers propagation delay as undesirable and attempts to mitigate its impact on throughput. The essential idea in this paper is to do simultaneous pairwise transmissions and utilize the propagation delay to avo...Show More

OCEANS'10 IEEE SYDNEY
Year: 2010 | Conference Paper |
Cited by: Papers (13)
Underwater acoustic networks can have large propagation delays as compared to typical packet durations, as a result of the low speed of sound in water. The ill effects of large propagation delay on medium access control (MAC) are well known. Conventional MAC protocol design for such networks focuses on mitigation of the impact of propagation delay. Most proposed protocols to date achieve, at best,...Show More

Unified simulation and implementation software framework for underwater MAC protocol development

Shiraz Shahabudeen;Mandar Chitre;Mehul Motani;Alan Low Yong Siah

OCEANS 2009
Year: 2009 | Conference Paper |
Cited by: Papers (15)
MAC protocol development for underwater acoustic modem has been an active research area for many years. The primary mode of investigation is through network simulations. Subsequent implementation in modems for testing in sea trials typically involves porting of simulation code into the appropriate programming language and software environment in a modem. Correct porting is critical since, if the m...Show More

OCEANS 2007 - Europe
Year: 2007 | Conference Paper |
Cited by: Papers (17)
This paper presents results from a study on using multiple communication channels simultaneously for effective networking in a small AUV network. AUVs can be highly mobile, leading to time-varying inter-node distances and a dynamic network topology. We try to exploit this mobility by using multiple acoustic modems operating at different frequency bands and suited for different ranges. We utilize a...Show More

As electromagnetic waves do not propagate well underwater, acoustics plays a key role in underwater communication. Due to significant differences in the characteristics of electromagnetic and acoustic channels, networking protocols for underwater systems differ from those developed for wired and wireless radio networks. Various schemes have been proposed for one or many aspects of underwater netwo...Show More
