A context storage scheme for sensornet

To addressing the self adaptation problem arises from sensornet, this paper argues that integrating context aware with sensornet is feasible. To build such a context aware sensornet, proper context description and storing mechanisms must be provided. It proposes RBLS, a role based local storage scheme. Aimed at providing context storage support for sensornet, RBLS stores contexts at node's local space and dynamically allocates extra spaces according to the roles a node holding. A "snapshot" is used by RBLS to record a neighbor's private contexts. Simulation results reveal that RBLS is simple and energy efficient.
