Abstract:
In this paper, we present a middleware architecture for coordination
services in sensor networks that facilitates interaction between
groups of sensors which monitor different
environmental events. It sits on top of the native routing
infrastructure and exports the abstraction of mobile communication
endpoints maintained
at the locations of such events. A single logical destination
is created and maintained for every environmental event of interest.
Such destinations are uniquely labeled and can be used for
communication by application-level algorithms for
coordination and sensory data management between the different
event locales. For example, they may facilitate
coordination, in a distributed intrusion scenario, among
nodes in the vicinity of the intruders.
We evaluate our middleware architecture using GloMoSim, a wireless network simulator. Our results illustrate the success of our architecture in maintaining event-related communication endpoints. We provide an analysis of how architectural and network dependent parameters affect our performance. Additionally we provide a proof of concept implementation on a real sensor network testbed (Berkeley's MICA Motes).
