Toward Optimal Data Aggregation in Random Wireless Sensor Networks

Data gathering is one of the most important services provided by wireless sensor networks (WSNs), Since the predominant traffic pattern in data gathering services is many-to-one communication, it is critical to understand the limitations of many-to-one information flows and devise efficient data aggregation protocols to support prolonged operations in WSNs. In this paper, we provide a theoretical characterization of data aggregation processes …
