SDN Controller Deployment for QoS Guarantees in Tactical Ad Hoc Networks
Xin Yan, Xiaodong Hu, Wen Liu · Wireless Communications and Mobile Computing · 2021
Tactical ad hoc networks (TANET) accomplish the corresponding tasks via a hopeful device‐to‐device connection mechanism for data transmission and resource management without a centralized foundation. Software‐defined networking (SDN) provides an evolution from the previous networks by decoupling the network control from data forwarding and providing a novel paradigm for network handling. Nevertheless, a SDN‐based strategy in TANET leads to various novel problems since the primary construction cannot be employed in mobile ad hoc networks anymore. In this paper, a new SDN‐based structure is constructed for TANET. Then, both delay and energy consumption (EC) are utilized to model the controller deployment and data‐plane assignment problems, by which quality‐of‐service (QoS) guarantees are realized. Afterwards, mixed‐integer programming (MIP) is adopted to solve the mentioned model. Finally, according to the experimental outcomes, it can be observed that the presented approach ensures the data‐plane delay and optimizes the EC.
