However, it is designed for static wireless sensor networks and is not suitable for mobile scenarios. When mobile nodes (MNs) exist in the 6LoWPAN network, repeated link disruptions and topology changes lead to data packets loss and affect network stability. An increasing number of mobile applications force the improvement of RPL protocols for supporting mobility. In this study, a distributed competition and mobility-aware RPL routing protocol (DCM\u2013RPL) is proposed to carry out mobility management and alleviate the network burden in the mobile scenario. A new preferred parent-discovering mechanism for MNs based on a distributed competition algorithm integrated with Objective Function is designed, which can dramatically reduce power consumption in the new parent node (PN)-discovering phase. To reduce data loss during the node-moving process, a packet-caching mechanism is proposed in the PN update phase. Finally, test-beds are set up and simulated in the Cooja simulator. Comparing the performance of the DCM\u2013RPL in terms of switching delay, energy consumption, and PDR with the RPL and its mobility-aware variant (mRPL and EC\u2013MRPL); the simulation results show that the proposed scheme maintains efficiency. <\/jats:p>","DOI":"10.1142\/s0218126623500834","type":"journal-article","created":{"date-parts":[[2022,9,12]],"date-time":"2022-09-12T01:36:51Z","timestamp":1662946611000},"source":"Crossref","is-referenced-by-count":0,"title":["DCM\u2013RPL: A Distributed Competition Mobility Management Scheme for RPL\/6LoWPAN"],"prefix":"10.1142","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1272-1871","authenticated-orcid":false,"given":"Chenggen","family":"Pu","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Chongqing University of Posts and Telecommunications, No. 2 Chongwen Road, Nan\u2019an District, Chongqing 400065, P.
