Security and power consumption comparisons of wireless sensor networks

In this paper, security and power consumption of wireless Personal and local area network systems are compared. For this reason the most widely used wireless communication standards, WLAN (IEEE 802.11), Bluetooth (IEEE 802.15.1), ZigBee (IEEE 802.15.4), WirelessHART and UWB, are subjected for security and power consumption comparisons. In particular Machine to Machine (M2M) and internet of things (IOT) definitions are called a promising application areas supposed to appear in the industry in near future. Thus, this paper studies the technologies, which takes place in M2M and IOT communications, in order to provide an insight into their application areas.
