Abstract
In this paper, we study about Software Defined Networking (SDN) is centralized controller of the network. It has maintained the information regarding the whole network which being able to optimize the available network resources and makes the route decision for forward packets. In Traditional networks, each device possess with own configuration and state which makes difficult to networking and expensive to maintain and forward packets. It also uses multiple routing algorithms for many different devices such as routers and switches and no centralized approach for routing. SDN architecture is centralized and support different routing algorithms for packet forwarding in emerging changes in networks. SDN usage is rapidly increased in networking to meet today challenges. This paper discuss on SDN with Wireless Sensor Network for load balancing between the nodes in communication. Due to Mobility of node in Wireless sensor network need of load balance .Also discussed various issues related with SDN performance in wireless sensor Network.
Highlights
A wireless sensor network (WSN) is a collection of sensor nodes to record the physical condition of environment such as temperature, pressure etc. and to collect the information
Software defined networking is a new paradigm in network to manage control and data plane easier .Software Defined Networking (SDN) is an open source to control and manage network elements
In this paper proposed a work to make faultless continuous transmission and load balanced handover of destination node in WSN with SDN.Openflow protocol is not able to characterize the wireless sensor network and controller cannot manage the access point in infrastructure layer
Summary
A wireless sensor network (WSN) is a collection of sensor nodes to record the physical condition of environment such as temperature, pressure etc. and to collect the information. In WSN there is a limitation for increase in energy usage due to battery power and delay in information transmission due to mobility. To overcome limitation a load balancing approach for communication of sensor network is possible through Software defined network [1]. SDN controller is central which separate routers and switches to make a forwarding devices simple.SDN provide automated load balancing, routing and reduced hardware costs. SDN with WSN impose more challenges as limited in energy consumption, memory, processing resources and application related to nodes performance.
