CEMulti-core Architecture for Optimization of Energy over Heterogeneous Environment with High Performance Smart Sensor Devices

Nowadays, it is unusual for an electronic system to be without sensors, thus sensing plays an important part in everyday life. To this, the field of image processing is an added advantage as it stores image data and makes it readily available for parallel processing. The wireless sensor nodes over heterogeneous networks exhibit radio communication always with highest energy consumption. Multicore processors are more suitable for real time applications compared to traditional modern microcontrollers of sensor nodes in terms of improvement in their energy consumption rate. To significantly reduce the energy consumption, the usage of off-the-shelf low power microcontroller with appropriate processing core has to be considered. The proposed CEMulti-core architecture incorporated with the MIPS single core processor and multicore processor is simulated and the experimental results are compared and analyzed for their speedup, clock cycles and the time required for execution. Thus enabling the sensor node over heterogeneous networks to process large sized images with increase in energy efficiency.
