Sažetak
A Wireless Sensor Network consists of a large number of sensor nodes that are usually battery powered and deployed in large areas in which changing or recharging batteries may be impractical or completely unfeasible. Therefore, energy efficiency represents one of the main design objectives for these networks. Since most of the energy is consumed by the radio communication, the development of Medium Access Control protocols able to minimize the radio energy consumption is a very attractive research area. This paper presents an energy efficient communication protocol and its implementation in the Contiki Operating System. The performances and the portability of the proposed solution are thoroughly evaluated by means of both simulations, carried out using the Contiki simulation tools (i.e., Cooja and MPSim), and test beds based on two different platforms. Obtained results show that the proposed scheme significantly reduces the sensor nodes power consumption compared to the IEEE 802.15.4 standard solution already implemented in Contiki.
