As of today, Underwater Acoustic Networks (UANs) are heavily dependent on commercially available acoustic modems. While commercial modems are often able to support specific applications, they are typically not flexible enough to satisfy the requirements of next-generation UANs, which need to be able to adapt their communication and networking protocols in real-time based on the environmental and application conditions. To address these needs, we present SEANet (Software-dEfined Acoustic Networking), a modular, evolving software-defined framework for UAN devices that offers the necessary flexibility to adapt and satisfy different application and system requirements through a well-defined set of functionalities at the physical, data-link, network, and application layers of the networking protocol stack. SEANet is based on a structured modular architecture that enables real-time reconfiguration at different layers, provides a flexible platform for the deployment of new protocol designs and enhancements, and ensures software portability for platform independence. Moreover, we present a prototype of a low-cost, fully reconfigurable underwater sensing platform that implements the SEANet framework, and discuss performance evaluation results from water tank tests.

Wireless intra-body networks of implantable biomedical devices have the potential to enable revolutionary healthcare and clinical applications. In our previous work we investigated the use of ultrasonic waves as an alternative to radio frequency (RF) waves as physical carrier of information, and proposed Ultrasonic WideBand (UsWB), the first ultrasonic integrated physical and medium access control (MAC) layer protocol.In this paper, we compare the performance of the UsWB MAC protocol with two existing MAC protocols originally designed for wireless RF-based networks, ALOHA and Carrier Sense Multiple Access (CSMA). In particular, we discuss the protocol performance in terms of (i) average network throughput and packet drop rate, (ii) average short-term fairness, (iii) average packet delay, and (iv) energy consumption per bit. We show that UsWB outperforms ALOHA in terms of throughput, while CSMA can achieve comparable performance under specific setups. However, both ALOHA and CSMA have very high packet drop rates as compared to UsWB. The latter is capable of keeping the packet drop rate under a pre-defined threshold. Moreover, UsWB significantly outperforms both ALOHA and CSMA in terms of short-term fairness, and average packet delays. Finally, CSMA has the highest energy consumption per bit, because of long idle sensing times, whereas UsWB has the lowest, and it can be further reduced by trading throughput for energy consumption through energy-minimizing rate adaptation.
