摘要：Energy efficient transmission mechanism is a significant issue in Wireless Sensor Network to prolong its lifetime. Energy efficiency and lifetime awareness fetching important design concerns in clustered WSN.The challenging choice of selecting modulation and coding in different channel condition is focused on this work. Furthermore, the performance of modulation and error control codes is analyzed with distance between nodes taken as a constraint. The sensor event transmission mechanism is analyzed with GMSK system with Golay, RS (Reed-Solomon) and convolutional codes. The performance of transmission approach are evaluated by calculating the energy required to transmit a bit under AWGN (Additive White Gaussian Noise) and Rayleigh channel.It also examine the adaptability of GMSK technique for WSN. Our focus is on enhancing the lifetime of each cluster of WSN using proper selection of the modulation and coding schemes for different sensors
