In recent years originally static and single purpose Wireless Sensor Networks have moved
towards applications that need support for mobility and multiple purposes. These heterogeneous
applications and services demand for a framework which distributes and discovers the various
services so that other pieces of equipment can use them. Markus Becker studies extends
analytically models simulates and employs the so called Trickle algorithm in measurements in a
Wireless Sensor Network test bed for the service distribution. The obtained results apply to
the application of the Trickle algorithm at lower protocol layers e.g. for routing as well.
Given application delay requirements the author derives the realizable distances and number of
nodes for two network topologies from the 95 percentiles obtained by simulation.
