“…To inform SDNSNs on routing decisions, controller generates flowmod messages, which contain elements of flow entries. For the adopted format of flow table, payload of these messages doesn't exceed 4B if matching is done on one block of packet header bytes [12].…”

-Energy efficiency is one of the key requirements in Wireless Sensor Networks (WSNs). In order to optimize energy usage at sensor nodes, this paper proposes a new network architecture that relies on concepts of Software Defined Networking (SDN). Since SDN is a relatively new technology, originally envisioned for wired networks, it cannot be expected to get immediately and completely adopted in WSN domain, regardless of potential benefits. For this reason, we consider incremental SDN deployment where SDN nodes coexist with traditional sensor nodes, and propose a new routing algorithm for SDN controller that prolongs the WSN lifetime even when a small percentage of SDN nodes is deployed.

“…Due to specificity of WSN environment, the format of flow table is modified compared to the OpenFlow specification. We assumed the table format proposed in [12]. As shown in Table 1, matching rules contain several window blocks which refer to blocks of bytes that will be matched against the packets.…”

“…Software-Defined Wireless Networking (SDWN) [3], [4] is based on providing programmatic centralized control of the network outside wireless-enabled devices (Access PointsAPs) which enforce the data plane instructions (i.e.. policy decisions) received from the controllers. The principles of SDWN are similar to those of Software-Defined Networking (SDN) [2], i.e., a networking approach based on a programmatic separation of the control plane (aka.…”

“…It is believed that the concept of Software-Defined Networking (SDN) [2] applied to wireless networks, commonly referred to as Software-Defined Wireless Networking (SDWN) [3], [4], can break down current structural barriers and contribute to a more innovative ecosystem. In spirit of (wired) SDN principles, SDWN decouples control and data planes, enabling the wireless network to become programmable by abstracting the underlying infrastructure from applications and network services that are offered with higherlevel APIs.…”

“…In spirit of (wired) SDN principles, SDWN decouples control and data planes, enabling the wireless network to become programmable by abstracting the underlying infrastructure from applications and network services that are offered with higherlevel APIs. As a consequence, wireless network infrastructures are presented with new deployment paths of research ideas around seamless communication over heterogeneous wireless networks [5], high transferring data over wireless medium [6], energy optimization [7], among others [3], [4].…”

Software-Defined Wireless Networking (SDWN) is an emerging approach based on decoupling radio control functions from the radio data plane through programmatic interfaces. Despite diverse ongoing efforts to realize the vision of SDWN, many questions remain open from multiple perspectives such as means to rapid prototype and experiment candidate software solutions applicable to real world deployments. To this end, emulation of SDWN has the potential to boost research and development efforts by re-using existing protocol and application stacks while mimicking the behavior of real wireless networks. In this article, we provide an in-depth discussion on that matter focusing on the Mininet-WiFi emulator design to fill a gap in the experimental platform space. We showcase the applicability of our emulator in an SDN wireless context by illustrating the support of a number of use cases aiming to address the question on how far we can go in realistic SDWN experiments, including comparisons to the results obtained in a wireless testbed. Finally, we discuss the ability to replay packet-level and radio signal traces captured in the real testbed towards a virtual yet realistic emulation environment in support of SDWN research.
