However, in hostile environments where node connectivity is severely compromised, the system performance can be greatly affected. In this work, we consider such a hostile environment where sensor nodes cannot directly communicate to some neighboring nodes. Building on this, we propose a distributed data gathering scheme where data packets are stored in different nodes throughout the network instead to considering a single sink node. As such, if nodes are destroyed or damaged, some information can still be retrieved. To evaluate the performance of the system, we consider the properties of different graphs that describe the connections among nodes. It is shown that the degree distribution of the graph has an important impact on the performance of the system. A teletraffic analysis is developed to study the average buffer size and average packet delay. To this end, we propose a<jats:italic>reference node<\/jats:italic>approach, which entails an approximation for the mathematical modeling of these networks that effectively simplifies the analysis and approximates the overall performance of the system.<\/jats:p>","DOI":"10.1155\/2019\/7409329","type":"journal-article","created":{"date-parts":[[2019,11,19]],"date-time":"2019-11-19T23:31:08Z","timestamp":1574206268000},"page":"1-22","source":"Crossref","is-referenced-by-count":2,"title":["On the Use of Graphs for Node Connectivity in Wireless Sensor Networks for Hostile Environments"],"prefix":"10.1155","volume":"2019","author":[{"given":"Emmanuel","family":"Garc\u00eda-Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Simulation and Modeling Laboratory, CIC-Instituto Polit\u00e9cnico Nacional, Mexico City, Mexico"}]},{"given":"Juan C.","family":"Chimal-Egu\u00eda","sequence":"additional","affiliation":[{"name":"Simulation and Modeling Laboratory, CIC-Instituto Polit\u00e9cnico Nacional, Mexico City, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1020-6806","authenticated-orcid":true,"given":"Mario E.","family":"Rivero-Angeles","sequence":"additional","affiliation":[{"name":"Network and Data Science Laboratory, CIC-Instituto Polit\u00e9cnico Nacional, Mexico City, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0894-9494","authenticated-orcid":true,"given":"Vicent","family":"Pla","sequence":"additional","affiliation":[{"name":"Universitat Polit\u00e8cnica de Val\u00e8ncia, Valencia, Spain"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1177\/1550147717748898"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/3986321"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.3390\/s17112553"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2018.02.010"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2017.12.008"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/tnet.2017.2653109"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.3390\/s18061691"},{"year":"1988","key":"8"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-05382-9"},{"year":"1985","key":"10"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1137\/070710111"},{"key":"12","doi-asserted-by":"crossref","first-page":"477","DOI":"10.21136\/CPM.1955.108220","volume":"80","year":"1955","journal-title":"\u010casopis Pro P\u011bstov\u00e1n\u00ed Matematiky (in Czech)"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1137\/0110037"},{"year":"1973","key":"14"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/0012-365X(91)90311-O"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/7409329.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/7409329.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/7409329.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,2,4]],"date-time":"2021-02-04T04:54:40Z","timestamp":1612414480000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2019\/7409329\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11,19]]},"references-count":15,"alternative-id":["7409329","7409329"],"URL":"https:\/\/doi.org\/10.1155\/2019\/7409329","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2019,11,19]]}}}
