Data Aggregation and Security Issues in Wireless Sensor Networks:A Survey

Abstract

Wireless sensor networks (WSNs) are normally composed of low powered, inexpensive device that is constrained in terms of memory, computation and communication. To reduce communication overhead and resource consumption in WSN, data aggregation is used to increase network lifetime. Hence, the design of an efficient data aggregation protocol is an important issues and inherently challenging task of robust WSN. In this paper, various types of Data Aggregation in WSN, security issues are studied and also author presented possible key research issues of WSN data aggregation.
