Distributed Minimum Energy Data Gathering and Aggregation in Sensor Networks
Recent technological advances have enabled the production of low-cost sensor nodes. These sensor nodes are small in size, and are equipped with limited sensing, processing, and transmission capabilities. They can be deployed in large numbers to form sensor networks with the ability of distributed wireless sensing. In practice, sensor nodes are deployed in an ad-hoc fashion over the area of interest. After the deployment, sensor nodes collect data from their surroundings, encode the data, and transmit them to the sink node via wireless channels.
