Special Issue Information

Dear Colleagues,

In recent years, Sensor Networks (SN) and Internet of Things (IoT) seem to have become an emerging technology, which is gaining popularity among researchers. Software-defined networking (SDN) is an emerging network design and management paradigm that offers a flexible way to reduce the complexity of network management and configuration. Sensor Networks are composed of resource-constrained devices, with the purpose of gathering information from the environment. These devices can sense, process, and communicate, increasing the amount of information available and enhancing our perception of the world. SDN-based wireless sensor networks (SDWSNs) consist of a set of software-defined sensor nodes equipped with different types of sensors. In SDWSN, sensor nodes are able to conduct different sensing tasks according to the programs injected into them, and the functionalities of these nodes can also be dynamically configured by injecting different application-specific programs. SDWSNs adopt the characteristics of SDN and can provide energy-efficient solutions for various problems, such as topology management, sleep scheduling, routing, localization, etc.

IoT is considered a bridging platform that connects the physical world and the cyber space, so that innovative applications and services with high efficiency and productivity can be obtained. However, in-depth research efforts on systems, networks, and architectures of IoT for efficient large-scale deployments are still required to fill the gaps between satisfying quality of service requirements and cost-effective implementations and operations. The different planes of networking devices can be separated with the application of SDN. This helps in achieving exceptional flexibility in programmability and enormous potentials for optimization of network resource usage. Thus, SDN is an emerging technology that addresses these gaps by enabling new ways of IoT communications and services through evolving networking devices and systems with adaptive and scalable functionalities.

The aim of this Special Issue is to invite researchers to submit original manuscripts that cover and explore these gaps. This Special Issue solicits novel papers on a broad range of topics, including, but not limited to: Cutting edge technologies, novel studies, and innovative developments that can realize and elevate the effectiveness and advantages of the emerging SDN-assisted sensor network and IoT techniques, and related areas.

All submitted papers to this Special Issue are to focus on state-of-the-art research in various aspects of smarter Sensor networks and IoT, supported with SDN, from academic and industry viewpoints. Topics of interests include, but are not limited to:

  • Architecture, networking protocols, QoS, and cross-layer optimization design;
  • Communications for SDN–IoT;
  • Field trials and deployments of SDN–IoT;
  • IoT cloud platform based on SDN;

Wireless Sensor Networks (WSNs) are usually troubled with constrained energy and complicated network topology which can be mitigated by introducing a mobile agent node. Due to the numerous nodes present especially in large scale networks, it is time-consuming for the collector to traverse all nodes, and significant latency exists within the network. Therefore, the moving path of the collector should be well scheduled to achieve a shorter length for efficient data gathering. Much attention has been paid to mobile agent moving trajectory panning, but the result has limitations in terms of energy consumption and network latency. In this paper, we adopt a hybrid method called HM-ACOPSO which combines ant colony optimization (ACO) and particle swarm optimization (PSO) to schedule an efficient moving path for the mobile agent. In HM-ACOPSO, the sensor field is divided into clusters, and the mobile agent traverses the cluster heads (CHs) in a sequence ordered by ACO. The anchor node of each CHs is selected in the range of communication by the mobile agent using PSO based on the traverse sequence. The communication range adjusts dynamically, and the anchor nodes merge in a duplicated covering area for further performance improvement. Numerous simulation results prove that the presented method outperforms some similar works in terms of energy consumption and data gathering efficiency. Full article

Load Balancing (LB) is one of the most important tasks required to maximize network performance, scalability and robustness. Nowadays, with the emergence of Software-Defined Networking (SDN), LB for SDN has become a very important issue. SDN decouples the control plane from the data forwarding plane to implement centralized control of the whole network. LB assigns the network traffic to the resources in such a way that no one resource is overloaded and therefore the overall performance is maximized. The Ant Colony Optimization (ACO) algorithm has been recognized to be effective for LB of SDN among several existing optimization algorithms. The convergence latency and searching optimal solution are the key criteria of ACO. In this paper, a novel dynamic LB scheme that integrates genetic algorithm (GA) with ACO for further enhancing the performance of SDN is proposed. It capitalizes the merit of fast global search of GA and efficient search of an optimal solution of ACO. Computer simulation results show that the proposed scheme substantially improves the Round Robin and ACO algorithm in terms of the rate of searching optimal path, round trip time, and packet loss rate.

Software-defined networks (SDNs) are improving the controllability and flexibility of networks as an innovative network architecture paradigm. Segment routing (SR) exploits an end-to-end logical path and is composed of a sequence of segments as an effective routing strategy. Each segment is represented by a middle point. The combination of SR and SDN can meet the differentiated business needs of users and can quickly deploy applications. In this paper, we propose two routing algorithms based on SR in SDN. The algorithms aim to save the cost of the path, alleviate the congestion of networks, and formulate the selection strategy by comprehensively evaluating the value of paths. The simulation results show that compared with existing algorithms, the two proposed algorithms can effectively reduce the consumption of paths and better balance the load of the network. Furthermore, the proposed algorithms take into account the preferences of users, actualize differentiated business networks, and achieve a larger comprehensive evaluation value of the path compared with other algorithms.

In virtualized sensor networks, virtual machines (VMs) share the same hardware for sensing service consolidation and saving power. For those VMs that reside in the same hardware, frequent interdomain data transfers are invoked for data analytics, and sensor collaboration and actuation. Traditional ways of interdomain communications are based on virtual network interfaces of bilateral VMs for data sending and receiving. Since these network communications use TCP/IP (Transmission Control Protocol/Internet Protocol) stacks, they result in lengthy communication paths and frequent kernel interactions, which deteriorate the I/O (Input/Output) performance of involved VMs. In this paper, we propose an optimized interdomain communication approach based on shared memory to improve the interdomain communication performance of multiple VMs residing in the same sensor hardware. In our approach, the sending data are shared in memory pages maintained by the hypervisor, and the data are not transferred through the virtual network interface via a TCP/IP stack. To avoid security trapping, the shared data are mapped in the user space of each VM involved in the communication, therefore reducing tedious system calls and frequent kernel context switches. In implementation, the shared memory is created by a customized shared-device kernel module that has bidirectional event channels between both communicating VMs. For performance optimization, we use state flags in a circular buffer to reduce wait-and-notify operations and system calls during communications. Experimental results show that our proposed approach can provide five times higher throughput and 2.5 times less latency than traditional TCP/IP communication via a virtual network interface.
