Software Defined Network-based Scalable Resource Discovery for Internet of Things

Abstract

Geo-distributed and heterog eneous Internet of Things (IoT) devices can gener ate hug e amoun t of da ta. Ine fficien t manag emen t of IoT-da ta promotes netw ork cong estion and increases computa tional overhead on the da ta-processing entities. Traditional netw orking architecture, tha t is lack of functional abstr action and monitoring capabilities, often fails to meet the dynamics of IoT. Softw are Define Netw ork (SDN) can be a viable al terna tiv e of the traditional netw orking architecture while dealing with IoT. In SDN, manag emen t, monitoring and context sensing of the connected componen ts are sim plifie and can be customized. In this paper , SDN-sensed contextual inf orma tion of di fferen t componen ts (computa tional entities, netw ork, IoT devices) are combined tog ether to facilita te scalable resource discov ery in IoT. The proposed policy targ ets balanced processing and cong estion-less forw arding of IoT-da ta. Through sim ula tion studies, it has been demonstr ated tha t the SDN-based resource discov ery in IoT outperf orms the traditional netw orking based approaches in terms of resource discov ery time and Quality of Service (QoS) satisf action rate.

Software Defined Networks: a Comparative Study and Quality of Services Evaluation

“…Software-defined networking is able to organize and manage up to thousands of network devices through a point of management, network monitoring both in terms of resources and connectivity, change the behavior of the networks automatically, maximizing the use of devices such as network bandwidth optimization, load balancing, traffic engineering and others associated with the programmability and scalability [5], [6]. Previously published studies have explored how SDN can provide better mechanisms for common network management and configuration tasks across a variety of problems including Internet of Things [7], cellular SDN [8], and data centre networks [9].…”

IoT Protocols: Connecting Devices in Smart Environments

“…Medical equipment that are connected can remotely monitor patients in hospitals, resulting in better care and the ability to identify health problems early on. Sensors built into machinery in factories improve operating efficiency, forecast maintenance requirements, and optimize manufacturing processes [5].…”

Software-Defined Multi-domain Tactical Networks: Foundations and Future Directions

“…Most of the existing SDN-based solutions are applicable to wired networks [9]. On the other hand, SDN operations in wireless networks is complicated due to the presence of a large number of unsettled access points.…”
