Ultra low power consumption, short transmission time and efficient data coding wireless communication technology for MWSNs

摘要

Mobile Wireless Sensor Networks (MWSNs) can be defined as a wireless sensor network (WSN) in which sensor nodes are mobile. It has recently become an area of attractive research interest. MWSNs have been attracting increasing interest for supporting a new generation of ubiquitous computing systems with great potential for many applications. However, the communication paradigms in this type of network differ from the ones associated to traditional wireless networks, triggering the need for efficient wireless communication technology. Several wireless technologies have emerged ranging from short and medium distance. Bluetooth, ZigBee and Impulse Radio Ultra Wide Band (IR-UWB) are three popular wireless communications technologies. Due to its various features and advantages (especially low power consumption and low complexity), IR-UWB is a key solution for MWSNs. In this paper, we study and evaluate the performance of IR-UWB for WSNs. We used MiXiM platform under OMNet++ simulator, to analyze and evaluate the main features and advantages of this new technology in terms of transmission time, data coding efficiency and power consumption.
