Medium Access for Underwater Acoustic Sensor Networks
The underwater acoustic channel has many fundamentally different properties to the conventional radio-based wireless channel. Communication is changed drastically by acoustic propagation speeds that are five orders of magnitude slower than radio. This, coupled with bandwidth limitations, high transmit energy cost, complex multi-path effects, and high bit-error rates make the issue of medium acc...
متن کاملCSMA/ECA: Carrier Sense Multiple Access with Enhanced Collision Avoidance
This paper presents CSMA/ECA, which combines the efficiency of reservation-based protocols and the simplicity of random access mechanisms. The maximum efficiency of CSMA/CA with optimal parameter adjustment is easily exceeded by CSMA/ECA, even when fixed parameters are used by the latter. CSMA/ECA stations fairly coexist with legacy CSMA/CA and increase the portion of time that is devoted to su...
متن کاملA Hierarchical Time Division Multiple Access Medium Access Control Protocol for Clustered Underwater Acoustic Networks
A hierarchical time division multiple access (HTDMA) medium access control (MAC) protocol is proposed for clustered mobile underwater acoustic networks. HTDMA consists of two TDMA scheduling protocols (i.e., TDMA1 and TDMA2) in order to accommodate mobile underwater nodes (UNs). TDMA1 is executed among surface stations (e.g., buoys) using terrestrial wireless communication in order to share mob...
متن کاملAn Enhanced Aloha based Medium Access Control Protocol for Underwater Sensor Networks
In Underwater Acoustic Sensor Networks (UASN) designing Medium Access Control (MAC) protocol is a challenging issue. This is due to low bandwidth and high propagation delay in UASN. This paper proposes a MAC protocol for UASN called Aloha with Virtual Back off Algorithm (AlohaV). The VBA approach is the collision avoidance mechanism for wireless networks. In this proposed work we use VBA with n...
متن کاملAn Efficient Medium Access Control Protocol for under Water Acoustic Sensor Network
Unlike a terrestrial wireless communication which uses radio waves, underwater communication relies on acoustic waves. The long latency and limited bandwidth pose great challenges in Underwater Media Access Control (MAC) design. So this paper proposes a new MAC protocol for wireless sensor acoustic network which are adaptable to underwater environment. This new protocol is based on the classic ...
