Abstract: In this paper, we present a family of adaptive protocols, called SPIN (Sensor Protocols for Information via Negotiation), that efficiently disseminates information among sensors in an energy-constrained wireless sensor network.Nodes running a SPIN communication protocol name their data using high-level data descriptors, called meta-data.They use meta-data negotiations to eliminate the transmission of redundant data throughout the network.In addition, SPIN nodes can base their communication decisions both upon application-specific knowledge of the data and upon knowledge of the resources that are available to them.This allows the sensors to efficiently distribute data given a limited energy supply.We simulate and analyze the performance of two specific SPIN protocols, comparing them to other possible approaches and a theoretically optimal protocol.We find that the SPIN protocols can deliver 60% more data for a given amount of energy than conventional approaches.We also find that, in terms of dissemination rate and energy usage, the SPlN protocols perform close to the theoretical optimum.
