“…In wireless sensor networks (WSNs), different trust establishment (TE) methods, technologies and mechanisms, such as fuzzy logic [1,2], bio-inspired [3,4,5], and deterministic- and probabilistic-based approaches [6,7,8,9,10,11,12,13], have recently been proposed. In general, TE can be used in WSNs for two purposes: cooperation improvement and security enhancement [7,10,11,12].…”
