Data aggregation and privacy preserving techniques in wireless sensor networks: A survey

Author(s): Prajna Mayadi
Abstract: The research advances and applicability of wireless sensor networks (WSNs) have introduced many new promising applications including habitat monitoring, battlefield surveillance and target tracking. The energy consumption is the major issue to be considered for WSNs which is occupied by data communication among nodes in maximum proportion. Many sensor applications collect data from an individual node which is aggregated at a base station. To reduce energy consumption, in-network aggregation can be performed at intermediate nodes en-route to the base station. As wireless sensor networks are usually deployed in remote and hostile environments to transmit sensitive information, sensor nodes are prone to node compromise attacks and security issues such as data confidentiality and integrity are extremely important. Hence, wireless sensor network protocols, e.g., data aggregation protocol, must be designed with security in mind. The paper investigates the relationship between security and data aggregation process.
