Therefore, it is important to find out the most efficient SRD configurations in terms of their performance in high\u2010contention scenarios; moreover, it is crucial to ensure that SRD networks do not impair the radio systems that operate in neighboring licensed spectrum, and vice versa. This paper addresses the previous issues by simulating a building automation application scenario, where 2 channel access mechanisms, namely duty cycling (DC) and carrier sense multiple access (CSMA), are evaluated independently and in coexisting scenarios, and, also, in the presence of a Long\u2010Term Evolution (LTE) user equipment. The CSMA protocol analysis shows that very high or very low transmission powers decrease its performance, and thus, either this parameter has to be calibrated or the gateways location has to be adjusted; for the DC protocol, its performance is only affected by the number of gateways within the SRD network, which should be as high as possible. Regarding the coexistence of the DC and CSMA schemes, the results show that CSMA\u2010based SRDs can successfully operate in the presence of a significant number of DC\u2010based SRDs, whereas the contrary is not true. Lastly, it is proven that an LTE user equipment may harm the SRD network, although this effect can be mitigated by adjusting the SRDs transmission power; furthermore, the SRDs interference on LTE systems is found to be negligible.<\/jats:p>","DOI":"10.1002\/ett.3301","type":"journal-article","created":{"date-parts":[[2018,3,15]],"date-time":"2018-03-15T13:50:44Z","timestamp":1521121844000},"source":"Crossref","is-referenced-by-count":0,"title":["Coexistence of DC and CSMA in SRD channel access and resilience to LTE interference: A simulator\u2010based analysis"],"prefix":"10.1002","volume":"29","author":[{"given":"Rita","family":"Bandeira","sequence":"first","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Instituto Superior T\u00e9cnico University of Lisbon Lisbon Portugal"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-7208-4598","authenticated-orcid":false,"given":"Ivo","family":"Sousa","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Instituto Superior T\u00e9cnico University of Lisbon Lisbon Portugal"}]},{"given":"Maria Paula","family":"Queluz","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Instituto Superior T\u00e9cnico University of Lisbon Lisbon Portugal"}]},{"given":"Ant\u00f3nio","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Instituto Superior T\u00e9cnico University of Lisbon Lisbon Portugal"}]}],"member":"311","published-online":{"date-parts":[[2018,3,15]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"CEPT.ECC Report 181: Improving Spectrum Efficiency in the SRD Bands.2012."},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2010.020510.00058"},{"key":"e_1_2_8_4_1","unstructured":"IMST.Channel Access Rules for SRDs.2012."},{"key":"e_1_2_8_5_1","unstructured":"CEPT.ECC Report 207: Adjacent Band Co\u2010existence of SRDs in the Band 863\u2010870 MHz in Light of the LTE Usage Below 862 MHz.2014."},{"key":"e_1_2_8_6_1","unstructured":"CEPT.ECC Report 261: Short Range Devices in the frequency range 862\u2010870 MHz.2017."},{"key":"e_1_2_8_7_1","unstructured":"CEPT.ECC Report 014: Report from CEPT to the European Commission in response to the mandate to develop a strategy to improve the effectiveness and flexibility of spectrum availability for Short Range Devices (SRDs).2006."},{"key":"e_1_2_8_8_1","unstructured":"European Commission.Radio Spectrum Policy Group Report on Strategic Sectoral Spectrum Needs.2013."},{"key":"e_1_2_8_9_1","unstructured":"ETSI.The European Regulatory Environment for Radio Equipment and Spectrum: an Introduction.2016."},{"key":"e_1_2_8_10_1","unstructured":"CEPT.ECC Recommendation 70\u201003.2017."},{"key":"e_1_2_8_11_1","doi-asserted-by":"crossref","unstructured":"LauridsenM VejlgaardB KovacsIZ NguyenH MogensenP.Interference measurements in the European 868 MHz ISM band with focus on LoRa and SigFox.
