  Distributed systems become more and more important to our life. Especially in
areas like Smart Home and the Internet of Things (IoT) reliable low-power
sensor networks become increasingly important. For ensuring this there are a
lot of trust metrics. In this paper we compare a model of a distributed
low-power sensor network including one root node and the corresponding Simple
Trust Metric to the requirements from "Representation of Trust and Reputation
in Self-Managed Computing Systems" [1], the Weighted Trust Metric and the
Weighted Simple Exponential Smoothing
