The transmission rate between two nodes is usually very low in underwater acoustic networks due to the low available bandwidth of underwater acoustic channels. Therefore, increasing the transmission parallelism among network nodes is one of the most effective ways to improve the performance of underwater acoustic networks. In this paper, we propose a new collision-free hybrid medium access control (MAC) protocol for distributed multi-channel underwater acoustic networks. In the proposed protocol, handshaking and data transmission are implemented as a pipeline on multiple acoustic channels. Handshaking is implemented using the time division multiple access (TDMA) technique in a dedicated control channel, which can support multiple successful handshakes in a transmission cycle and avoid collision in the cost of additional delay. Data packets are transmitted in one or multiple data channels, where an algorithm for optimizing the transmission schedule according to the inter-nodal propagation delays is proposed to achieve collision-free parallel data transmission. Replication computation technique, which is usually used in parallel computation to reduce the requirement of communication or execution time, is used in the data packet scheduling to reduce communication overhead in distributed environments. Simulation results show that the proposed protocol outperforms the slotted floor acquisition multiple access (SFAMA), reverse opportunistic packet appending (ROPA), and distributed scheduling based concurrent transmission (DSCT) protocols in throughput, packet delivery rate, and average energy consumption in the price of larger end-to-end delay introduced by TDMA based handshaking.

“…WOSS provides a highly integrated solution for UAN modeling, where the user can specify the time of the year and geographic locations of the nodes, and the simulator automatically queries the relevant databases, fetches the corresponding sea bottom characteristics and the SSPs, uses them as environment parameters for BELLHOP beam tracing, and integrates the BELLHOP outputs into the network simulation. Similarly to WOSS, the Aqua-Sim simulator [33] [45] combines the ns-2 network simulation suite with a UWA channel model to produce an integrated UAN simulation tool. However, the channel model used in Aqua-Sim is based on a simple analytical signal attenuation model [16] and a constant 1500 m/s propagation speed of acoustic waves.…”

This manuscript was submitted to IEEE Access on 12 Jun 2020.<div><br></div><div>Abstract:</div><div><br></div><div>Simulation forms an important part of the development and empirical evaluation of underwater acoustic network (UAN) protocols. The key feature of a credible network simulation model is a realistic channel model. A common approach to simulating realistic underwater acoustic (UWA) channels is by using specialised beam tracing software such as BELLHOP. However, BELLHOP and similar modeling software typically require knowledge of ocean acoustics and a substantial programming effort from UAN protocol designers to integrate it into their research. In this paper, we bridge the gap between low level channel modeling via beam tracing and automated channel modeling, e.g. via the World Ocean Simulation System (WOSS), by providing a distilled UWA channel modeling tutorial from the network protocol design point of view. The tutorial is accompanied by our MATLAB simulation code that interfaces with BELLHOP to produce channel data for UAN simulations. As part of the tutorial, we describe two methods of incorporating such channel data into network simulations, including a case study for each of them: 1) directly importing the data as a look-up table, 2) using the data to create a statistical channel model. The primary aim of this paper is to provide a useful learning resource and modeling tool for UAN protocol researchers. Initial insights into the UAN protocol design and performance provided by the statistical channel modeling approach presented in this paper demonstrate its potential as a powerful modeling tool for future UAN research.<br></div>

We will show evaluation of performance Vector Based Void Avoidance (VBVA) routing for application mobility node on Underwater Sensor Network (UWSN). The research method is building the simulation using Network Simulator (NS-2.30) under operating system Linux Ubuntu. The installed NS-2.30 is added with Aqua-Sim module developed by Peng Xie. The final output from NS-2 will be visualized to graphic and table that will be analyzed using measurement metric packet delivery ratio, throughput, delay, and packet loss and energy consumption using AWK scripts with added with several modifications. The result of this simulation indicates that increasing number of nodes will result in loss of quality. One of them is decrease in packet delivery ratio. The decline was caused by that many packet collisions happen.
