Question

In SDN - based sensor network , one can manage

Answer 1

Software Defined Networks are considered an efficient and flexible network framework for managing large scale networks in particular as it decouple between hardware and software and facilitates global network optimizations.  

Incorporating SDN concepts into Wireless Sensor Networks opens interesting research challenges.  

This paper provides an architecture for applying SDN to WSN.  

Architecture depends on recent enhanced features of OpenFlow to enable re-configuring sensor behavior and network forwarding tables for changes as arrival of new sensors in user requests and to apply dynamic in-network aggregation and filtering options.  

Evaluation of our approach for specific case of in-network aggregation and its beneficial impact on number of sent messages is presented.
