Abstract

Recent advancement in hardware and the availability of bandwidth open scope for multichannel communication in underwater wireless sensor networks. Utilizing multiple channels for data and control packets in bursty traffic networks can reduce collisions due to several contending nodes. The paper presents a synchronous reservation-based multichannel ordered contention MAC protocol for deep underwater high data rate bottom monitoring applications to improve the overall network throughput. This protocol is proposed as an enhancement over ordered contention MAC (OCMAC) protocol to deal with bursty traffic by reducing transmission collisions. It does so by enabling nodes to employ multichannel technique along with the scheduling technique of OCMAC. The protocol uses separate channels for channel reservation and data transmission. The throughput performance of the network has been analyzed and validated through simulation. Simulation-based results have shown that MOC-MAC outperforms OCMAC in terms of throughput.

水下无线传感器网络的多通道有序竞争MAC协议

摘要

硬件的最新进展和带宽的可用性为水下无线传感器网络中的多通道通信提供了开放范围。在突发流量网络中为数据和控制数据包使用多个通道可以减少由于多个竞争节点而引起的冲突。本文提出了一种基于同步预留的多通道有序竞争MAC协议，用于深水下高数据速率底部监视应用程序，以提高整体网络吞吐量。提出该协议是对有序竞争MAC（OCMAC）协议的增强，以通过减少传输冲突来处理突发流量。它通过使节点能够采用多通道技术以及OCMAC的调度技术来实现。该协议使用单独的信道进行信道保留和数据传输。网络的吞吐量性能已通过仿真进行了分析和验证。基于仿真的结果表明，在吞吐量方面，MOC-MAC优于OCMAC。
