An Adaptive OFDMA-Based MAC Protocol for Underwater Acoustic Wireless Sensor Networks
Underwater acoustic wireless sensor networks (UAWSNs) have many applications across various civilian and military domains. However, they suffer from the limited available bandwidth of acoustic signals and harsh underwater conditions. In this work, we present an Orthogonal Frequency Division Multiple Access (OFDMA)-based Media Access Control (MAC) protocol that is configurable to suit the operat...
متن کاملA MACA-based MAC protocol for Underwater Acoustic Sensor Networks
The medium access control (MAC) protocol design of underwater acoustic sensor networks (UWASNs) faces many challenges: the power limitation at nodes, long propagation delay, low data rates, etc. These challenges of underwater acoustic channels result in the unsuitable usage of terrestrial networks MAC protocol in UWASNs. Moreover, the long propagation delay causes a serious problem for the MAC ...

متن کاملGame Theory based Energy Efficient Hybrid MAC Protocol for Lifetime Enhancement of Wireless Sensor Network
Wireless Sensor Networks (WSNs) comprising of tiny, power-constrained nodes are getting very popular due to their potential uses in wide applications like monitoring of environmental conditions, various military and civilian applications. The critical issue in the node is energy consumption since it is operated using battery, therefore its lifetime should be maximized for effective utilization ...
متن کاملFactors affecting MAC Protocol Performance in Underwater Wireless Sensor Networks
Underwater wireless sensor networks (UWSNs) has gained attention to researcher due to their wide range of applications. However, due to their power constrains and limitations, an energy efficient MAC protocol is required. Existing MAC protocols for terrestrial WSNs are not sufficient to solve the issues in UWSNs. Therefore, to design a new MAC protocol for UWSNs it is required to study the fact...
