Abstract

Nowadays is era of Internet of Things. Load balancing is an important studying issues in internet of things that intended to improving energy consuming with distributing loads. The IoT needs load distribution because of the use of Wireless Sensor Networks (WSN) as one of the most well-known IoT connection participators. Improved routing in network is one of methods of load distributing and balancing energy consuming. Software Defined Network (SDN) is a new network architecture with could reach this goal, using central controller. In this paper balanced routing based on Leach is presented, which is one of important routings in wireless network. Proposed algorithm is done using direct monitoring of information of load of link and the running situation. This routing named SDN-Improved Leach which can send different flows to BS with the best route. In this routing, using the proposed new controller architecture and defining different layers and units for it, optimal routing for current transmission is considered. This routing directs packets from one source to another according to network conditions. At the end, proposed routing is compared with Leach and improved Leach algorithms which are some of important routings considering different parameters. Comparisons is done in the number of live nodes, mean consumed energy, receiving data and number of lost packets. comparing diagrams are drowning at the end of paper that indicates predominance of proposed algorithm in compare of those two algorithms.
