The energy efficiency of sensor nodes and the network as a whole is of specific importance. One possible area where energy savings can be made lies within the routing protocols employed; however, these protocols are typically only simulated. In this work we develop a WSN testbed and conduct investigations on the fidelity of simulated energy-aware WNS routing protocols. It was found that the real-world performance of these energy-aware protocols was significantly lower than that predicted by simulation models. This can be mainly attributed to chip-level effects not taken into account by simulation models, leading to simulated results that cannot be achieved in real-world deployments. This work illuminates the shortfalls of existing simulation models and suggests ways in which these models can be improved. Additionally the testbed allows other energy-aware routing protocols to be investigated easily. <\/jats:p>","DOI":"10.1155\/2014\/795268","type":"journal-article","created":{"date-parts":[[2014,6,5]],"date-time":"2014-06-05T21:11:45Z","timestamp":1402002705000},"page":"795268","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["A Wireless Sensor Network Testbed for the Evaluation of Energy-Aware Routing Schemes"],"prefix":"10.1177","volume":"10","author":[{"given":"Magdalena J.","family":"Grobler","sequence":"first","affiliation":[{"name":"TeleNet Research Group, School of Electrical, Electronic and Computer Engineering, North-West University, Potchefstroom Campus, Potchefstroom 2520, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8613-1436","authenticated-orcid":false,"given":"Henri-Jean","family":"Marais","sequence":"additional","affiliation":[{"name":"TeleNet Research Group, School of Electrical, Electronic and Computer Engineering, North-West University, Potchefstroom Campus, Potchefstroom 2520, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joubert G.
