A Survey on Collaborative Sensor Networks

PhD Qualifying Examination


Title: "A Survey on Collaborative Sensor Networks"

Mr. Yuan HE


Abstract:

Sensor networks have been widely deployed in all kinds of applications. In
the near future, we expect to witness the proliferation of sensor networks
with a variety of functions that requires a comprehensive collaboration
mechanism among them. Specific designs are necessary to manipulate a
fabric of multiple sensor networks, facilitate the collaboration among
them, and support efficient data sensing, aggregation, storage,
transmission, and query processing. In this survey, through comparison and
analysis of existing works, we present a new taxonomy of collaborative
sensor networks based on the architectures and the methodologies of
organizing different modules of a system. We find that a cross-layer
design simultaneously guaranteeing the energy efficiency of underlying
sensor networks and the quality of services for users is a challenging
issue which has not been well studied. We also discuss the design space in
this field and point out potential research directions.
