However, existing medium access control schemes are either over-coordinated (fixed-schedule-based schemes) or under-coordinated (prioritized contention-based schemes), failing to address this problem efficiently. This paper introduces a new medium access scheme, called FrugalMAC, aiming to provide timely, ondemand, and contention-free medium access by relying on a progressive, dynamic reservation mechanism coupled with reservation vectors. A node sleeps whenever the channel is not needed for data communication and slot reservation. In addition, FrugalMAC employs reservation pipelining and an admission control mechanism to support end-to-end real-time stream delivery. We have implemented a prototype of FrugalMAC in our sensor network testbed. Our preliminary results show that FrugalMAC has high energy efficiency and effectively supports timeliness.<\/jats:p>","DOI":"10.1145\/1923641.1923657","type":"journal-article","created":{"date-parts":[[2011,1,6]],"date-time":"2011-01-06T16:20:36Z","timestamp":1294330836000},"page":"43-45","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Dynamic channel reservations for wireless multihop communications"],"prefix":"10.1145","volume":"14","author":[{"given":"Jun","family":"Yi","sequence":"first","affiliation":[{"name":"University of Notre Dame, IN"}]},{"given":"Christian","family":"Poellabauer","sequence":"additional","affiliation":[{"name":"University of Notre Dame, IN"}]},{"given":"Xiaobo Sharon","family":"Hu","sequence":"additional","affiliation":[{"name":"University of Notre Dame, IN"}]},{"given":"Thidapat","family":"Chantem","sequence":"additional","affiliation":[{"name":"University of Notre Dame, IN"}]},{"given":"Liqiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Indiana University South Bend, IN"}]}],"member":"320","published-online":{"date-parts":[[2010,12,27]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1182807.1182838"},{"issue":"7","key":"e_1_2_1_2_1","first-page":"1002","volume":"91","author":"Stankovic J.
