Minimizing Energy Consumption with New Coloring Scheduling in Wireless Sensor Networks

چکیده مقاله

We propose a novel approach to design a coloring Wakeup Schedule (CWS) for the radio of the nodes in wireless sensor networks, in order to reduce the end-to-end latency with energy efficient data transmission. In this letter, a novel Coloring Wake-up Schedule (CWS) is presented for the radio of the nodes in the wireless sensor networks. The aim of this approach is reducing the end-to-end latency and energy consumption in the data transmission. In the CWS, a particular color is assigned to each cell of the nodes. By this, the packet of the node can transfer along the shortest path to the sink node; the nodes find their neighbour according to their transmission range and choose the neighbour that is near than any nodes to the sink node. Therefore the mentioned-schedule decreases the useless activities of the nodes which caused to save the energy. Also, a specific grid is defined for the situation of the CWS nodes to improve the routing. The various simulations prove the usefulness of the proposed CWS compared to the other schedules in wireless sensor networks.
