Abstract

The applications of wireless sensors/body area networks comprise a wide variety of scenarios. In most of them, The Networks is composed a large number of nodes deployed in an extensive are in WSN.It is quite necessary that the data must be transferred in a secure way to the WBAN system coordinator. We must also take care of the fact that the data of one patient must not get mixed up with another one?s. The patient?s data is highly private and it must have limited access and must be highly secure. This paper compares the two recently proposed protocols ATTEMPT and SIMPLE along with simulation results. Later sink position is optimized.
