An Efficient Data Transmission Based on O-Leach OFDM Rule for Heterogeneous WSN

Abstract

This paper proposes a directing convention for the uses of Wireless Sensor Network. It is a convention dependent on the LEACH convention yet utilizing some optimization techniques. This O-LEACH (Optimized LEACH) based on OFDM rule (Orthogonal Frequency Division Multiplexing). OFDM is allocated different frequencies for each sub-channels this reduces the time and interference between channels. Also ,this model efficiently handles the power allocation by using a Water Filling Algorithm. By which to increase the Network lifetime and throughput. Reduce the time delay. MATLAB 2016a proposes the simulated method.
