Intelligent transportation systems (ITS) have encountered a number of problems due to the
continuous growth in the number of vehicles, the heterogeneous network environments and …

During the past few years, software-defined networking (SDN) has become a successful
architecture that decouples the control plane from the data plane. SDN has the capability to …

Software Defined Network (SDN) has been considered as one of the most promising next-
generation network solutions due to its network programmability. However, the upgrade from …

In this paper, we propose models of mathematical programming for the Placement Problem
of Controllers (CPP). in wireless Software-Defined Networks (SDNs). This problem consists …

In this paper, we analyze the problem of managing users from different slices connecting to
a software‐defined network (SDN). We seek to minimize the propagation latency between …

In this paper, we consider the problem of assigning users to switches and controllers at
minimum connectivity costs. We simultaneously minimize the existing latency between …

In this paper, we propose mixed-integer quadratic and linear programming models to
minimize the worst latency in software-defined wireless networks (SDNs). Our models are …

Most controller placement algorithms require as input the estimated number of controllers to
be placed in software defined wide area networks (SD-WANs). However, determining the …

This paper presents a novel algorithm for placing multiple controllers in a software defined
wireless sensor network (SDWSN). The algorithm is designed to address scalability and …

This work proposes an efficient controller placement algorithm in SDN to address scalability
challenges in dense sensor networks. An important question must be answered: given …
