Wake-up receiver for radio-on-demand wireless LANs

A new wake-up radio architecture for wireless sensor networks

The last decades have been really hungry in new ways to reduce energy consumption. That is especially true when talking about wireless sensor networks in general and home multimedia networks in particular, since electrical energy consumption is the bottleneck of the network. One of the most energy-consuming functional block of an equipment is the radio front end, and methods to switch it off du...

Effect of Hash Function on Performance of Low Power Wake up Receiver for Wireless Sensor Network

Next generation network will consist of different types of wireless networks like WSN, Wi-Fi, WiMAX, UMTS, LTE and etc. Wireless Sensor Network (WSN) finds unique and special application as compared to the said networks because sensors are deployed in a very secret, awkward and hostile environment like battle field etc. Various wireless sensor nodes are interconnected and form a Wireless Sensor...

Wake-Up-Receiver Concepts - Capabilities and Limitations

A promising idea for optimising the power consumption of mobile communication devices represents the usage of an additional ultra-low-power receiver unit, which is able to control the main transceiver in order to reduce the standby power consumption of the overall system. Such a Wake-Up-Receiver (WuRx) unit senses the medium and switches on the communication interfaces in case of an external re...

Performance of Wireless Lans in Radio Channels

Wireless Local Area Networks (WLANs) are faced with the presence of hidden terminals and the possibility of capture when operating in multipath radio channels. These phenomena complicate both their design and performance analysis. This paper considers the performance of wireless LANs with Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol in fading channels. To assess the...
