Abstract

Localisation of sensors in underwater internet of things (UIoTs) is difficult due to the mobility. This changing makes the routing decisions difficult, which results in unreliable communication. This paper proposes adaptive transmission-based geographic and opportunistic routing (ATGOR) protocol for reliable communication between nodes. ATGOR operates in two parts: election of a small cube to avoid redundant transmissions and selection of reliable nodes which forward data from the selected small cube for optimal transmissions. Furthermore, to guarantee the reliability of the data packets in a harsh acoustic environment, we propose mobility aware ATGOR (MA-ATGOR), which predicts the locations of neighbouring sensor nodes for successful data delivery. In addition, prediction of tthe locations of the sensor nodes helps in avoiding the void holes along with high packet delivery. The performance of the proposed routing protocols is validated based on the PDR, number of void nodes and energy consumption per packet, through simulations.

水下物联网自适应传输的地理机会路由算法

水下物联网(uiot)中传感器的定位由于其移动性而变得困难。这种变化使得路由决策变得困难，从而导致不可靠的通信。提出了一种基于自适应传输的地理机会路由(ATGOR)协议，用于节点间的可靠通信。ATGOR操作分为两部分:选择一个小立方体以避免冗余传输;选择可靠的节点，从选择的小立方体转发数据以实现最佳传输。此外，为了保证数据包在恶劣声学环境下的可靠性，我们提出了移动感知ATGOR (MA-ATGOR)，它预测相邻传感器节点的位置以成功传输数据。此外，对传感器节点位置的预测有助于避免空穴以及高数据包传输。通过仿真验证了所提路由协议在PDR、空洞节点数和每包能耗方面的性能。版权所有©2022 Inderscience Enterprises Ltd。一种新的自适应传输地理机会路由算法[j]

期刊介绍： Web services are providing declarative interfaces to services offered by systems on the Internet, including messaging protocols, standard interfaces, directory services, as well as security layers, for efficient/effective business application integration. Grid computing has emerged as a global platform to support organisations for coordinated sharing of distributed data, applications, and processes. It has also started to leverage web services to define standard interfaces for business services. IJWGS addresses web and grid service technology, emphasising issues of architecture, implementation, and standardisation.
