An energy-oriented evaluation of communication optimizations for microsensor networks

Wireless, microsensor networks have potential for enabling a myriad of applications for sensing and controlling the physical world. While architectural/circuit-level techniques are critical for the success of these networks, software optimizations are also expected to become instrumental in extracting the maximum benefits from the performance and energy behavior angles. In this paper, focusing on a sensor network where the sensors form a two-dimensional mesh, we experimentally evaluate a set of compiler-directed communication optimizations from the energy perspective. Our experimental results obtained using a set of array-intensive benchmarks show significant reductions in communication energy spent during execution.
