IEEE 802.15 Task Group 6 presented several schemes to reduce such interference, but these schemes are still not proper solutions for BANs. We present a novel distributed TDMA-based beacon interval shifting scheme that reduces interference in the BANs. A design goal of the scheme is to avoid the wakeup period of each BAN coinciding with other networks by employing carrier sensing before a beacon transmission. We analyze the beacon interval shifting scheme and investigate the proper back-off length when the channel is busy. We compare the performance of the proposed scheme with the schemes presented in IEEE 802.15 Task Group 6 using an OMNeT++ simulation. The simulation results show that the proposed scheme has a lower packet loss, energy consumption, and delivery-latency than the schemes of IEEE 802.15 Task Group 6.<\/jats:p>","DOI":"10.3390\/s120810930","type":"journal-article","created":{"date-parts":[[2012,8,7]],"date-time":"2012-08-07T10:56:27Z","timestamp":1344336987000},"page":"10930-10946","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["A Beacon Interval Shifting Scheme for Interference Mitigation in Body Area Networks"],"prefix":"10.3390","volume":"12","author":[{"given":"Seungku","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Korea University, Seoul 136-713, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seokhwan","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Korea University, Seoul 136-713, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Woo","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Korea University, Seoul 136-713, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doo-Seop","family":"Eom","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Korea University, Seoul 136-713, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,8,7]]},"reference":[{"unstructured":"IEEE 802.15 WPAN Task Group 6 Body Area Networks (BAN).
