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.
