—Since sensor nodes use batteries as their source of energy, energy-based routing becomes an important requirement to extend network lifetime. This routing is done using the node...
Abstract—The sparse network topology, coupled with the limited availability of reference nodes in Under Water Sensor Network (UWSN), significantly reduces the effectiveness of m...
— 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...
Abstract--Optimal deployment and accurate localization of sensor nodes have a strong influence on the performance of a wireless sensor network (WSN). This paper considers real-time...
