A new service discovery architecture for sensor networks

Because wireless sensor networks (WSNs) as ad hoc networks allow devices to communicate dynamically without fixed infrastructure and centralized administration, they pose unique challenges on how informations collected by and stored within the network could be queried and accessed while saving devices power consumption. In this paper, we present a new distributed architecture for service location in WSNs that preserves ubiquitous information access. While traditional name and location services provide a direct mapping between services and their locations at predetermined nodes, our architecture relies on dynamically identified locations servers, to adapt to the changing nature of wireless sensor networks. To achieve this goal, our architecture relies on an efficient peer-to-peer algorithm: tapestry.
