Abstract
The Internet of Underwater Things (IoUT) is an emerging area in marine science and engineering. It has witnessed significant research and development attention from both academia and industries due to its growing underwater use cases in oceanographic data collection, pollution monitoring, seismic monitoring, tactical surveillance, and assisted navigation for waterway transport. Information dissemination in the underwater network environment is very critical considering network dynamism, unattainable nodes, and limited resources of the tiny IoUT devices. Existing techniques are majorly based on location-centric beacon messages, which results in higher energy consumption, and wastage of computing resources in tiny IoUT devices. Towards this end, this paper presents an efficient void aware (EVA) framework for information dissemination in IoUT environment. Network architecture is modeled considering potential void region identification in the underwater network environment. An efficient void aware (EVA) information dissemination framework is proposed focusing on detecting void network region, and intelligent void aware data forwarding. The comparative performance evaluation attests to the benefits of the proposed framework in terms of energy consumption, network lifetime, packet delivery ratio, and end-to-end delay for information dissemination in IoUT.
Highlights
Due to numerous implications in domains such as ecological, academic, industrial, and economic, the Internet of Underwater Things (IoUTs) has recently attracted the interest of many research and development activities in maritime industries [1,2,3,4]
The transmission range has been set equal to 250 m as it basically appropriates for such underwater networking applications and the initial energy is assigned to 100 J with 15 s packet generation time and size is 64 bytes
The findings demonstrate that Void-Aware Pressure Routing (VAPR) achieves a good packet delivery ratio comparable to efficient void aware (EVA), it consumes roughly 34% less energy than VAPR in the same situation
Summary
Due to numerous implications in domains such as ecological, academic, industrial, and economic, the Internet of Underwater Things (IoUTs) has recently attracted the interest of many research and development activities in maritime industries [1,2,3,4]. To cope with void sensors, current methods employ either geolocation data (location-based) or semi-location information (beacon-based) [13,21] Using such methods increase the energy consumption which limits the applicability in the IoUT scenario. Void-Aware Pressure Routing (VAPR) [23] and the Inherently Void Avoidance Routing (IVAR) [24] uses semi-geo information provided by the sink to identify the void nodes and find the alternate route, which is not practically suitable in most underwater networking applications [7] In this context, an efficient void aware (EVA) information dissemination routing framework is presented in this paper for enabling IoUT. The performance evaluation of the proposed EVA framework is discussed in Section 4 considering the comparative analysis of experimental results with the existing techniques
