An Efficient RRBN Size Communication Based Power Saving Scheme for Wireless Sensor Networks

Since battery technology has not progressed as rapidly as semiconductor technology, power efficiency has become increasingly important in wireless sensor networking, in addition to the traditional quality and performance measures, such as Band width, throughput, and fairness. Wireless sensor networks typically require low cost devices and low power applications. Hence, such networks usually employ radios with only simple modulation techniques such as ASK, OOK and FSK [9].We present in this paper, a energy efficient communication schemes for wireless sensor networks which are a redundant radix based number (RBN) representation i.e. RRBN Size Comm (Redundant Binary Number Silent through Zero digit Communication) scheme . We propose a transceiver design that uses a hybrid modulation scheme utilizing FSK the cost/complexity of the radio devices low. Considering an n-bit data representation and assuming that each of the 2 binary strings is equally likely occur, theoretically obtainable fraction of energy savings by using our proposed RRBN Size Comm transmission protocol is, on the average, Simulation results demonstrate that compared binary FSK, our proposed implementation can extend the batter life of devices from about 33% to 62% on an average in applications like healthcare and wireless Sensor networks for agriculture.
