Survey On Aggregation Protocols In Mobile Sensing
Mobile sensing applications play a major role in obtaining the desired statistics from multiple mobile users. In
todays world, cell phones come with multiple sensors which enables the aggregator to provide collective information. In the
existing system, there is bidirectional interchange between the mobile nodes and the aggregator or high processing overhead.
The communications between the untrusted aggregator and the mobile node requires high level of privacy and this is
achieved by generating secret keys, not known to each other. Key generation is implemented using sum aggregation protocol
which can scale to large systems.
