Without the network model, node can’t communicate with each other. When a node sends data to any another node in that network either data flows directly or indirectly through number of different hops. Different layers are associated with the model having their objective and responsibility. In wireless sensor network (WSN), the nodes are communicated with their goals from time to time following the structure of the network, number of protocols working on different layers of the model. Here, our focus on the topology and routing protocols behaviour in WSN. Analysis on the act of routing protocol like DSDV, AOMDV, AODV and DSR over the different topologies like chain, grid and parking lot. And also considering the performance of responsive and unresponsive flow of the network. The results are analyzed depending upon the simulation metrics like throughput, delay, jitter, PDR (packet delivery ratio), packet drop. Simulations are done using NS2 and the graphs are plotted by using gnuplot.

Renewable based power generation is rising rapidly due to high energy demand and carbon issues. Partial shading effect of the PV system leads to a significant reduction of the energy yield and quantity of reduction is depending on the geometry of shading effect. The incremental conductance and integral controller are used in this paper to display the maximum power point in the PV device. During bad weather conditions, insulated PV systems do not have enough power to supply the consumer. The key suggestions of this paper are to use the deficient power needed for the PV system through grid and to fed the PV system surplus power to the grid. The new control mode is used to monitor the PV current that uses two control loops for feedback. The current mode control system is a scheme for regulating electronic DC-DC power converters. On a PV system using MATLAB/SIMULINK a complete model of 100KW grid connected solar photovoltaic system using current mode controlled two-level three-phase VSC.
