Abstract :
This paper evaluates energy level performance of three packet delivery schemes in a Wireless Sensor Networks (WSN) in presence of Rayleigh fading. Three different information delivery mechanisms are investigated using regenerative relays with or without error correction capability. Energy consumption for successful delivery of a data packet for each mechanism is evaluated and compared under several conditions of node density, bit rate, transmit power etc. Energy efficiency of different retransmission schemes are evaluated. Further an optimal packet length based on energy efficiency is derived.
