Given the end-to-end packet deadline [T.sub.max], using these definitions and constraints, the problem is to find a set of indicator functions ending up with 1 that minimizes the total routing cost from a data source node to a data sink node.
Data Collection is a fundamental functionality of many WSN applications, and is commonly implemented by nodes periodically taking sensor measurements and reporting the corresponding samples to a data sink. The data prediction strategy, applied on each node.
Our technique not only ensures that no trend about the sensitive data of a sensor node is released to any other nodes and adversaries, but also can aggregate and hide data for data privacy during transmissions to the data sink. Out of two parts of a complex number, the real part is used to hide the sampled data of a sensor node from its neighboring nodes and adversaries, whereas the imaginary part is used for data integrity.
Each data sink is allowed to specify its own desired data update rate.
