Resource Management of Maritime Edge Nodes for Collected Data Feedback

Abstract

With the development of marine economy, more marine applications emerge leading to more deployed sensors and more generated data. However, current marine Internet only provides low transmission rate constrained by limited communication resources and bad transmission environment. How to efficiently use these resources and guarantee quality-of-service (QoS) of applications need to be addressed. This paper proposes an online optimization resource management algorithm to improve the communication resource efficiency with guaranteed QoSs for different applications. This algorithm needs neither of the resource cost function nor QoS constraint function at the resource scheduling node. Furthermore, the gradient information, which is usually needed in learning strategies, is not required either. Instead, this algorithm performs resource management of both computation and communication resources in each time slot only based on the observation of the last time slot. With slot-by-slot resource allocation, the communication cost can be minimized to be suitable for maritime scenarios. In the meantime, a long-term delay constraint can be satisfied. Results show that the proposed algorithm achieves the goal of reducing communication cost while guaranteeing the delay-constraint of different applications. Although more computation resources will improve its performance, this algorithm still can obtain the minimized cost given a low computation resource.

Assessment of Innovative Architectures, Challenges and Solutions of Edge Intelligence

“…Comparing EC to cloud computing, there are several benefits: end-users' confidentiality is protected, data transmission is more efficient, network bandwidth is less burdened, and data centers' energy consumption is lessened. To reduce latency, Edge Nodes (ENs) may process, store, and send raw data produced by IoT devices than relying on centralized cloud platforms [26]. This eliminates duplicate data transfer.…”

Maritime Communications – Current State and the Future Potential with SDN and SDR

“…Furthermore, compared to terrestrial wireless communications, maritime wireless communications must take into account the combined air-water-land effects [1]. The diverse set of platforms of maritime communications widely acknowledged and accepted in the current literature [3][4][5], shown in Figure 2, are as follows -1. Land platform consists of satellite stations, cellular towers, and UAV stations among other things.…”
