Data Reduction Techniques in Sensor Networks Antonios Deligiannakis and Yannis Kotidis   View Paper (PDF)   Return to March 2005, In-Network Query Processing, Volume 28, Number 1 Abstract Recent advances in microelectronics have made feasible the deployment of sensor networks for a variety of monitoring and surveillance tasks. The severe energy constraints met in such networks make imperative the design of energy efficient protocols for communication, which often constitutes the largest source of energy drain, of the collected information. In this paper, we describe several techniques that can be applied for the reduction of the transmitted information in different application scenarios. ©2006 Association for Computing Machinery
