energy consumption is considered as a critical issue in wireless sensor networks (wsns). batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. an efcient solution to improve energy consumption and even trafc in wsns is data aggregation (da) that can reduce the number of transmissions. two main challenges for da are: (i)...

Fog computing is a potential solution for the Internet of Things in close connection with things and end-users. will easily transfer sensitive data without delaying distributed devices. Moreover, fog more real-time streaming applications, sensor networks, IoT which need high speed reliable internet connectivity.
