The transferring of the information from the source port to the destination port plays a vital role in our day to day life. The data which is confidential should be send in a platform where the exact data without any loss is received. The insufficient poor quality of data can have a negative impact on real time data processing. The data transmission path should be selected in such a way that the entire data should be received for the usage without any loss in the network link. The data should be received with the accuracy and with less delay. In this way a technology called Software Defined Networking (SDN) plays an important role in managing and controlling the various network conditions. In this way, an approach is being designed in this paper where SDN technology is being used to transfer the data with an appropriate path in order to receive the exact data. It is an application based approach so that the patient medical data is being send using SDN technology.

Transmitting images over the wireless channel require that optimum compression ratio be maintained along with good image quality. This becomes a critical issue especially at higher values of bit error rate (BER). Joint photographic experts group (JPEG) standard and its successor JPEG 2000 provide excellent compression ratio but image reconstruction becomes highly difficult under extreme noise conditions. We present a mapping technique which gives better compression as compared to the existing techniques. Also, its performance is excellent even for higher bit error rates (BERs). This is supported by the results presented for JPEG, JPEG 2000, as well as mapping technique under fading channel conditions. Moreover, it is observed that the presence of high levels of noise has negligible effect on the reconstruction of images encoded using mapping technique.
