Secure Data Aggregation in Wireless Sensor Networkssor lifetime is improved and the network works for a longer period of time. Data aggregation is one such technique where data originating at different sensors is combined and transmitted together. This in-network processing of data helps in reducing the wireless communication but it also makes the t

Preamble

Data Management Solutions in Networked Sensing Systems of solutions in this area, which we will explore in this chapter. The first is . which provide distributed processing of sensor data. The second is . which are centralized systems that deal with stream data flowing from sensors. And finally, some hybrid approaches have also recently appeared which

Stream-Based Real World Information Integration Frameworkdatory. The infrastructure design should be based on the philosophy of a novel framework beyond the relational data management for two reasons: First is the freshness of data. To keep sensor data fresh, an infrastructure should process data efficiently; this means conventional time consuming transac
