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.
