A standard Wireless Sensor Network comprises of a huge number of sensor nodes with data processing and communication capabilities. The sensor nodes pass the gathered data using radio transmitter, to a sink either straightforwardly or through other nodes in a multi-hop approach. Wireless Sensor Network is a power consuming system since nodes perform on restricted power supply which decreases its lifetime. Optimally selected modulation and coding is extremely vital technique in Wireless Sensor Networks. This paper surveys the performance of different modulation schemes and error control codes used in sensor networks. The survey also analyzes the role of modulation and coding techniques apply to different channel conditions to improve the lifetime of the clustered sensor network.
