Edge computing for IoT (Edge-IoT) is a promising framework that can help low-powered sensor networks to conduct complex computational tasks. Different from the existing works that focus on cooperative task execution for edge and sensor networks, in this paper, we investigate the problem of reliable data transmission in edge-aided sensor networks. Firstly, we discuss how edge servers can help to improve the data transmission of sensor networks. Secondly, we propose a forwarding scheme for edge nodes to forward packets according to coverage and corresponding interference. Thirdly, we propose an edge-based error recovery approach. By employing edge servers for data transmission and error recovery, the efficiency and reliability of data transmissions can be largely improved.<\/jats:p>","DOI":"10.3390\/s19092078","type":"journal-article","created":{"date-parts":[[2019,5,9]],"date-time":"2019-05-09T11:22:35Z","timestamp":1557400955000},"page":"2078","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Edge-Aided Reliable Data Transmission for Heterogeneous Edge-IoT Sensor Networks"],"prefix":"10.3390","volume":"19","author":[{"given":"Zhirong","family":"Xu","sequence":"first","affiliation":[{"name":"College of Computer Science, Zhejiang University, #38, Zheda Road, Hangzhou 310024, China"},{"name":"Netease (Hangzhou) Network Co., Ltd., Hangzhou 310052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming","family":"Cai","sequence":"additional","affiliation":[{"name":"College of Computer Science, Zhejiang University, #38, Zheda Road, Hangzhou 310024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoyan","family":"Li","sequence":"additional","affiliation":[{"name":"Netease (Hangzhou) Network Co., Ltd., Hangzhou 310052, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tianlei","family":"Hu","sequence":"additional","affiliation":[{"name":"College of Computer Science, Zhejiang University, #38, Zheda Road, Hangzhou 310024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qianshu","family":"Song","sequence":"additional","affiliation":[{"name":"Administrative Office, Zhejiang Association for Science and Technology, Hangzhou 310006, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"22","DOI":"10.1016\/j.comcom.2015.09.006","article-title":"A survey on wireless sensor networks for smart grid","volume":"71","author":"Fadel","year":"2015","journal-title":"Comput.
