Abstract [en]

We present a hardware platform for performing experimental studies of energy storage devices for low power wireless networks. It is based on a low-cost custom card that can apply fine-grain synthetic loads ? both charge and discharge ? to a set of batteries or capacitors and measure their response in detail. Loads can be defined from a "live" trace of a running wireless device, from a recorded trace, or programmatically via a script. This approach makes it practical to run well controlled, large scale, long running experiments and to obtain high precision and accuracy. We describe two proof-of-concept experiments using rechargeable Li coin cells and capacitors to demonstrate the capabilities of our platform.

Abstract [en]

The large number and wide diversity of IoT networks operating in unlicensed spectrum will create a complex and challenging interference environment. To avoid a 'tragedy of the commons', networks may need to more explicitly coordinate their use of the shared channel.

Abstract [en]

We study edge server support for multiple periodic real-time applications located in different clouds. The edge communicates both with sensor devices over wireless sensor networks and with applications over Internet type networks. The edge caches sensor data and can respond to multiple applications with different timing requirements to the data. The purpose of caching is to reduce the number of multiple direct accesses to the sensor since sensor communication is very energy expensive. However, the data will then age in the cache and eventually become stale for some application. A push update method and the concept of age of information is used to schedule data updates to the applications. An aging model for periodic updates is derived. We propose that the scheduling should take into account periodic sensor updates, the differences in the periodic application updates, the aging in the cache and communication variance. By numerical analysis we study the number of deadline misses for two different scheduling policies with respect to different periods.

Abstract [en]

The present invention relates to a method, call handling server (18), local wireless network (10) and computer program product for performing vertical handover of a wireless voice connection, which is a part of a voice connection set up between a portable communication (22) device and another device. The network comprises a number of access points (20) and the call handling server (18) for controlling voice connections to the portable device. The server comprises a control unit (24) that determines a handover situation for the wireless connection to the portable device based on a set of handover factors that comprise the position and movement of the portable communication device in an area of the local network and structural layout information of the area together with knowledge of where in this area there is insufficient coverage.
