WiFi Sensor Networks: A study of energy consumption

This paper describes an energy consumption analysis of a wireless sensor node with a WiFi transceiver and its feasibility in smart city developments. A description of energy budgeting strategies is detailed, from which a theoretical calculus is made to validate the node setup energy wise. Afterwards, a practical measurement of the consumption is effected with TCP/UDP transmission protocols and various scenarios. A final comparison is made with a common battery module to give an idea of the longevity obtainable.
