In this paper, a link is proposed for wireless body area sensor networks (WBASNs) for the transmission of electrocardiogram (ECG) signal. When the quantity of signal is very high, then it is beneficial that signal should be compressed before transmission. In that situation, the signal compression and error control schemes played an important role in the designing of link for WBASNs. In case of biological sensor network, it is very important that node consumed less power in transmission because the replacement of nodes is a very complex surgical procedure in many medical situations. A compressed sensing concept is introduced here. The main aspect of this paper is to present transmission strategy that provides fast and accurate transmission of ECG signals. In this the smart sensor nodes are utilized. These nodes having sensing, transformation and transmission capability. The nodes sense the ECG signals, and these signal are compressed by Walsh–Hadamard transform method. This compressed signal is transmitted to the module outside the human body. In this module, various error control coding and modulation operations are to be performed on signals, and after that, signals are transmitted to the final destination. The compressed signal occupied less storage space, and ECC provides high data rate. In that manner, the fast transmission of ECG data becomes possible on low data rate sensor network link.
