Abstract :A wireless sensor network (WSN) is a wireless network consisting of distributed autonomous devices using sensors to observe physical or environmental conditions. The energy consumption is very important for WSNs. The paper presents that measurement of the energy consumption of indoor environment. Ti CC2538 modules were used as WSN nodes and they were programmed via Contiki Operating System (OS). Simulator of Contiki OS is COOJA. The program was simulated with COOJA before being tried in real life. Then, measurements were taken directly from the module via Labview and DAQ card. The network used Low Energy Adaptive Clustering Hierarchy (Leach) protocol which is a very popular networking protocol for WSN. The nodes in the network were prevented to go in sleep mode. Therefore, measurements showed transmit and receive mode energy consumption. On the other hand, cluster head election period and transmission period of sensed data selected as short as possible to make measurements in a short time. The proposed measurement system can be used evaluate any new networking protocol more realistically.
