— In Wireless Sensor Networks (WSNs), symmetric key schemes may be used to provide security. Recently, a class of random key pre-distribution techniques have been proposed and in...
Wireless sensor networks (WSNs) are subject to significant resource constraints. Particularly, routing protocols for lowrate WSNs suffer from maintaining routing metrics and sta...
