Survey on Several Secure Data Aggregation Schemes in WSN

Abstract

Nowadays, wireless sensor network (WSN) are used on many fields such as health monitoring, environment monitoring and target tracking, wireless sensor network (WSN), it's nothing but set of great numbers of nodes deployed in specific zone, those nodes communicating with each other's, consequent great energy consumption because of that, the lifetime of network it will be very short. Data Aggregation (DA) one of many techniques which can help to reduce the energy consumption in (WSN), and prolong the lifetime of the network, but (DA) has many challenges, one of them is the security issues, several techniques have proposed for secure data aggregation in (WSNs). The main target of this paper to introduce to different data aggregation techniques, and then discuss Secure Data Aggregation (SDA) approaches and attacks, and then to survey presented schemes for (SDA) in (WSNs), finally a comparison between schemes in some parameters.
