Recent theoretical work has shown that ideal medium access protocol using optimal power control can improve channel utilization by up to a factor of \u221a\u03c1, where \u03c1 is the density of nodes in the region [1]. Although power control mechanisms have been extensively studied in theory and simulations, their practical evaluation has not been done throughly. Most of the power control mechanisms proposed in literature [3, 4, 5] assume a very fine grained handle on transmit power of wireless nodes and exercise this control to provide sophisticated mechanisms of sharing wireless medium among competing flows. In this work, we investigate the (in)feasibility of fine-grained power control in wireless networks using real testbed experiments. We perform detailed experiments to highlight fundamental issues with power control mechanisms, that cannot be captured by using a network simulator. Our experiments indicate that fine grained power control may not be a viable solution for indoor wireless networks and most power control mechanisms may need to be adapted to be suitable for practical settings.<\/jats:p>","DOI":"10.1145\/1282221.1282238","type":"journal-article","created":{"date-parts":[[2007,9,14]],"date-time":"2007-09-14T13:44:55Z","timestamp":1189777495000},"page":"65-66","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["On the (in)feasibility of fine grained power control"],"prefix":"10.1145","volume":"11","author":[{"given":"Vivek","family":"Shrivastava","sequence":"first","affiliation":[{"name":"University of Wisconsin Madison"}]},{"given":"Dheeraj","family":"Agrawal","sequence":"additional","affiliation":[{"name":"University of Wisconsin Madison"}]},{"given":"Arunesh","family":"Mishra","sequence":"additional","affiliation":[{"name":"University of Wisconsin Madison"}]},{"given":"Suman","family":"Banerjee","sequence":"additional","affiliation":[{"name":"University of Wisconsin Madison"}]},{"given":"Tamer","family":"Nadeem","sequence":"additional","affiliation":[{"name":"Siemens Research"}]}],"member":"320","published-online":{"date-parts":[[2007,4]]},"reference":[{"author":"Gupta P.","unstructured":"P.
