When the information in non-reachable areas is required, IoT wireless sensor network technologies have to be applied. Sensors fundamentally have energy limitations, and it is almost impossible to replace energy-depleted sensors that have been deployed in an inaccessible region. Therefore, moving healthy sensors into the sensing hole will recover the faulty sensor area. In rough surfaces, hopping sensors would be more appropriate than wheel-driven mobile sensors. Sensor relocation algorithms to recover sensing holes have been researched variously in the past. However, the majority of studies to date have been inadequate in reality, since they are nothing but theoretical studies which assume that all the topology in the network is known and then computes the shortest path based on the nonrealistic backing up knowledge\u2014The topology information. In this paper, we first propose a distributed hopping sensor relocation protocol. The possibility of movement of the hopping sensor is also considered to recover sensing holes and is not limited to applying the shortest path strategy. Finally, a performance analysis using OMNeT++ has demonstrated the solidification of the excellence of the proposed protocol.<\/jats:p>","DOI":"10.3390\/s19071567","type":"journal-article","created":{"date-parts":[[2019,4,2]],"date-time":"2019-04-02T03:21:26Z","timestamp":1554175286000},"page":"1567","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Energy and Distance-Aware Hopping Sensor Relocation for Wireless Sensor Networks"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2692-6883","authenticated-orcid":false,"given":"Moonseong","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Liberal Arts, Seoul Theological University, Bucheon 14754, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9578-7517","authenticated-orcid":false,"given":"Sooyeon","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Incheon National University, Incheon 22012, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6726-2599","authenticated-orcid":false,"given":"Woochan","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Incheon National University, Incheon 22012, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"531","DOI":"10.1109\/COMST.2016.2610963","article-title":"Networking for Big Data: A Survey","volume":"19","author":"Yu","year":"2017","journal-title":"IEEE Commun.
