Partition-Based Joint Placement of Gateway and Controller in SDN-Enabled Integrated Satellite-Terrestrial Networks

Abstract

The Integrated Satellite-Terrestrial Networks (ISTNs) with Software-Defined Networking (SDN) incorporated have become the emerging architecture and have attracted considerable attention recently. Therein, the joint gateway and controller placement problem is of fundamental significance for designing ISTNs with flexible and efficient management capabilities. Hence, how to achieve network reliability maximization with low network latency in the joint placement problem is worthy of in-depth study. In this paper, a network partition algorithm, Simulated Annealing Partition-based K-means (SAPKM), is proposed and analyzed for further ameliorating the problem. Experiments are performed on real network topologies to validate the effectiveness of our approach for the joint placement problem. Compared with the state-of-the-art existing works, numerical results show that SAPKM outperforms when deploying four or more controllers in terms of network reliability performance, network latency, and inter-plane latency with less than 2 ms to converge.

Performance Evaluation of a Full-Duplex Relaying-Enabled Satellite Sensor Network

“…Specifically, the system parameters are provided in Table 2. Furthermore, the transmitted powers are denoted as P 1 = P 2 = P without loss of generality [6][7][8][9]. Table 2.…”

“…Due to the potential in providing wide coverage and high transmission rate, satellite sensor networks have been regarded as an effective approach to provide telecommunication and multimedia services for users who are separated far away, especially when the line-of-sight (LoS) link is unavailable because of the masking effect [3][4][5]. Satellite relaying is known as a basic type for communication, tracking and data exchange for future integrated satellite-terrestrial scenarios [6]. Generally, the basic architectures of satellite relaying includes two widely adopted schemes, namely, amplify-and-forward (AF) and decode-and-forward (DF) relay protocols [7].…”

Controller Placement in SDN-enabled 5G Satellite-Terrestrial Networks

“…They propose an iterative approach based on simulated annealing and clustering, where in each iteration first the current gateway placement policy and then the controller placement is updated towards the convergence. In [18], the exact same problem under similar settings and with similar objectives has been considered with the only difference that the simulated annealing approach from [17] is augmented with a portioning phase (separately w.r.t gateways & controllers) to render several sub-problems of smaller size. Finally, in [19], a number of meta-heuristic approaches namely,…”

“…They propose an iterative approach which relying on simulated annealing and clustering, where in each iteration first the current gateway placement policy and then the controller placement is updated towards the convergence. In [35], the exact same problem under similar settings and with similar objectives has been taken with the only difference that the simulated annealing approach from [36] is augmented with a portioning phase (separately w.r.t gateways & controllers) to render several sub-problems of smaller size. Finally, in [37], a number of meta-heuristic approaches namely, simulated annealing, double simulated annealing, and genetic algorithm for the same problem has been considered and their performance is compared.…”
