Characterization of Throughput in Wireless Sensor Network for MAC and Routing Protocol

Wireless sensor network is set of sensor nodes which are accountable for transmission of data i.e. it send and receive data packets from one node to another node in network surround. Sensor nodes have various functionalities thus they requires more resources for improve performance in network. Among the different parameters in WSN throughput is vital parameter. Because when the nodes close to sink then it suffers heavy traffic load i.e. initially throughput increases when load increases at base station but at certain point it get decreases because of congestion or delay. Thus throughput value has to get optimized for better performance of WSN.
