This paper proposes a robust hybrid-MAC protocol for direct communication among M2M devices with gateway coordination. The proposed protocol combines the benefits of both contention-based and reservation-based MAC schemes. The authors assume that the contention and reservation portion of M2M devices is a frame structure, which is comprised of two sections: Contention Interval (CI) and Transmission Interval (TI). The CI is based on p-persistent CSMA mechanism, which allows M2M devices to compete for the transmission slots with equal priorities. After contention, only those devices, which have won time-slots, are allowed to transmit data packets during TI. In the authors' proposed MAC scheme, the TI is basically a TDMA frame and each M2M device is 802.11 enabled. Each M2M transmitter device and its corresponding one-hop distant receiver communicate using IEEE 802.11 DCF protocol within each TDMA slot to overcome the limitations of TDMA mechanism. The simulation results demonstrate the effectiveness of the proposed hybrid-MAC protocol.<\/p>","DOI":"10.4018\/ijmcmc.2016010104","type":"journal-article","created":{"date-parts":[[2016,3,21]],"date-time":"2016-03-21T17:29:15Z","timestamp":1458581355000},"page":"41-60","source":"Crossref","is-referenced-by-count":4,"title":["Throughput-Delay Evaluation of a Hybrid-MAC Protocol for M2M Communications"],"prefix":"10.4018","volume":"7","author":[{"given":"Pawan Kumar","family":"Verma","sequence":"first","affiliation":[{"name":"Motilal Nehru National Institute of Technology, Allahabad - 211004, India"}]},{"given":"Rajesh","family":"Verma","sequence":"additional","affiliation":[{"name":"Ideal Institute of Technology, Ghaziabad - 201003, India"}]},{"given":"Arun","family":"Prakash","sequence":"additional","affiliation":[{"name":"Motilal Nehru National Institute of Technology, Allahabad - 211004, India"}]},{"given":"Rajeev","family":"Tripathi","sequence":"additional","affiliation":[{"name":"Motilal Nehru National Institute of Technology, Allahabad - 211004, India"}]}],"member":"2432","container-title":["International Journal of Mobile Computing and Multimedia Communications"],"original-title":[],"language":"ng","link":[{"URL":"https:\/\/www.igi-global.com\/viewtitle.aspx?TitleId=148261","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T16:03:27Z","timestamp":1654099407000},"score":1,"resource":{"primary":{"URL":"https:\/\/services.igi-global.com\/resolvedoi\/resolve.aspx?doi=10.4018\/IJMCMC.2016010104"}},"subtitle":[""],"short-title":[],"issued":{"date-parts":[[2016,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2016,1]]}},"URL":"https:\/\/doi.org\/10.4018\/ijmcmc.2016010104","relation":{},"ISSN":["1937-9412","1937-9404"],"issn-type":[{"value":"1937-9412","type":"print"},{"value":"1937-9404","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,1,1]]}}}
