Relay selection methods for maximizing the lifetime of wireless sensor networks
Fábio Engel de Camargo, Taufik Abrão, Lajos Hanzo · 2013
Combined analytical and fuzzy techniques are proposed for improving the battery lifetime, performance, as well as energy efficiency of wireless sensor networks (WSNs) with the aid of efficient relay selection methods. We determine the best relay selection method by striking an appealing performance versus network lifetime tradeoff. Furthermore, the beneficial regions of cooperation are determined considering asymmetric traffic scenarios, where relaying provides energy saving.
