Various Techniques Used in Wireless Sensor Networks for Data Transfer

Nowadays the wireless sensor networking is the common way for data transfer. So, it is a big task to upload and download data securely without any data loss. as we know in the wireless sensor network there are several nodes which are used to transfer the data. To perform this task there are various data transport protocols available. In this paper, we analyze the various protocol which is used for data transfer in WSN. We also discuss the various challenges which are faced during the data transfer in WSN.
