WSN goodput and energy consumption for various wireless communication standards

This paper proposes a methodology for calculating the energy consumption and the throughput of a Wireless Sensor Network (WSN) taking into account retransmissions and data dropped due to collisions. For various scenarios, simulations are conducted using OPNET and utilizing off-the-shelf wireless communications standards such as ZigBee, Low-Power Wi-Fi and Wi-Fi. A figure of merit is then introduced for a fair comparison between the mentioned standards.
