Energy- and latency-aware simulation of battery-operated wireless embedded networks for home automation

In this paper we present a simulation-based approach to determine the impact of placement and duty-cycle of wireless embedded sensor actor network (WESAN) nodes on various parameters, such as expectable lifetime, latency and overall operability. It accurately reflects hardware characteristics, e.g. power consumption, switching times, and therefore enables analysis of the platform-specific effects on the nodes´ and the network´s performance. In order to validate the approach, a case study involving a battery-operated door access control application is presented.
