On the Potential of Structure-Free Data Aggregation in Sensor Networks

Data aggregation protocols can reduce the cost of communication, thereby extending the lifetime of sensor networks. Prior work on data aggregation protocols has focused on tree-based or cluster-based structured approaches. Although structured approaches are suited for data gathering applications, they incur high maintenance overhead in dynamic scenarios for event-based applications. The goal of the authors' work is to design techniques and protocols that lead to efficient data aggregation without explicit maintenance of a structure.
