Abstract

This paper evaluates energy level performance of three packet delivery schemes in a Wireless Sensor Networks (WSN) in multipath Rician fading channel. 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 and transmit power. Energy efficiency of different retransmission schemes are evaluated. Further an optimal packet length based on energy efficiency is derived. Impact of different level of severity of Rician fading on energy efficiency and energy consumption is also investigated. Impact of fixed and optimal packet size on energy consumption is analyzed.
