Underwater Wireless Sensor Network (UWSN) is emerging lots of attention due to its various types of characteristics and applications. Distinctive underwater characteristics leads to many challenges such as-high propagation delay, data losses, nodes mobility, localization, nodes deployment while designing any reliable and efficient routing protocol. In this paper, an extension of CDBR (Forwarding nodes...
Ubiquitous technology through sensor networks is being applied to numerous industrial fields specially to increase the quality of human life (QoL). Therefore, Wireless Sensor Networks (WSNs) lossless data is one of the communications challenges to provide accurate data. Although, end-to-end data retransmission has evolved as a reliable transportation in Internet, this method is not applicable to WSNs...
Wireless Sensor Networks (WSNs) can be used to monitor hazardous and inaccessible areas. The WSN is composed of several nodes each provided with its separated power supply, e.g. battery. Working in hardly accessible places it is preferable to assure the adoption of the minimum transmission power in order to prolong as much as possible the WSN's lifetime. Though, we have to keep in mind that the reliability...
In wireless sensor networks (WSNs), multi-path routing can find multiple paths from source node to sink node. In data transmission, multiple paths can be used to improve reliability, energy-efficiency, etc. In the literature, there have been many works about multi-path routing. But those multi-path routing protocols are not efficient as they cost much time and energy to construct multiple paths. In...
Wireless sensor networks (WSNs) usually work under harsh environment, so high packet loss rate is induced by the unreliable and error-prone wireless links. To cope with the problem, a competition and cooperation based reliable forwarding protocol (CCRF) is proposed. In CCRF, the characteristic of dense deployment of sensor nodes and broadcast feature of the wireless channel in WSN are utilized. Specifically,...
