Software Defined Network (SDN) for large-scale IP provider network is an open issue and different solutions were proposed. However, the hybrid IP networks in which both distributed and centralized approach provide centralization of SDN and reliability of distributed networks. The common approach in which SDN controls the prioritized traffic and OSPF (Open Shortest Path First) guarantees the operation of traffic. In this research, we propose the SDN segregation, which maintain central management over dispersed routing control. A given topology is split in some fields with OpenFlow enabled switches as in between nodes. OSPF enabled router triggered updates to other routers in other field via SDN switches. The centralized controller defines how two OSPF routers observe each other. There will be a tradeoff between central control of SDN and fault tolerance capability of OSPF. As we increase SDN nodes control will increase and fault tolerance capacity of overall network decreases. The novelty of research work for balanced topology segregation also offers the models for network management. To show the enhancement provided by hybrid network over routing protocol deployment we have deployed separate test beds for routing protocol and proposed hybrid network.

With the passage of time the speed of the computer processors is getting faster and theoretical concept of Software-Defined Radio (SDR) is now a practical reality. Universal software Radio peripheral (USRP) is a commercially available SDR platform from ettus research. This can be interfaced easily with various software developmental prototyping platform such as MATLAB and GNU Radio. In this project we have implemented well known transmit diversity scheme known as Alamouti for MIMO systems for the transmission and reception of data. Alamouti scheme allows the same data to be transmitted through multiple paths due to which if the data being transmitted encounters deep fades and is lost in its way it can be received through the other path. Complete design is made on MATLAB and GNU Radio.

Efficient spectrum utilization lies at the heart of next generation (xG) wireless communication networks. In this context, a thorough investigation into new and innovative spectrum management techniques as well as additional regulatory procedures are deemed necessary to evaluate the practical feasibility of these xG networks. This paper reviews the three possible modes for multi-operator spectrum sharing based on dynamic spectrum access (DSA) in 5th Generation (5G) networks, and identifies Licensed/Authorized Shared Access (LSA/ASA) mode to be practically most suitable candidate for better spectrum utilization. Existing spectrum sharing techniques exploiting time, frequency and space domain to realize efficient co-existence of multiple operators are discussed, and game theory (GT) framework has been recognized as an appropriate tool to model the interactions among multiple operators accessing the shared spectrum resources. In particular, the hybrid cooperativecompetitive game has been proposed as a promising model to incorporate key parameters that play a significant role in the practical Deployment of DSA-enabled xG networks.

Economic load dispatch is a non-linear, complex and constrained optimization problem. In this paper a bio inspired meta-heuristic optimization technique namely novel bat algorithm is proposed for solving economic load dispatch problem. The results of three unit thermal system without losses and six units thermal system inclusive of losses had shown that novel bat algorithm had outperformed Lagrange relaxation, lambda iteration method, genetic algorithm, particle swarm optimization, pattern search algorithm, modified bacterial foraging algorithm, intelligent water drop algorithm and traditional bat algorithm in term of the best global optimum solution and fastest convergence.

Quick advancements in the field of Energy utilization and production has been the key issue. The clean environment and green energy utilization for power production has remained the main point of attention. Low noise, longer and cheaper energy production costs has drawn the attention. But the intermittence in green energy production via these natural resources is the restriction in producing high efficiency and reliability in energy production. Different control schemes have been developed and many hierarchical structures have been proposed to achieve balanced energy from the renewable energy resources. These control schemes alter and addresses different issues in different ways to achieve sustainability but still the sustainability is the issue to be achieved. In this paper we have selected some recent control schemes in for to control the microgrids and finally presented a comparative analysis based on the schemes proposed.
