A complete scheme for distributed LU decomposition on wireless sensor networks

In this work we are proposing a light-weight energy-aware distributed LU decomposition on energy-constrained wireless sensor networks (WSN). This work builds a complete scheme for the distribution; it involves an efficient block-based distribution of the LU decomposition, a simple energy-aware task mapping, a light-weight TDMA transmission schedule where each node can infer its transmission time slot through a temporary code assigned to it. The proposed scheme achieves 4x speedup in computation, and decreases the average energy consumption by a factor of 3.79.
