Wireless sensor network supports reliable monitoring of the given network based upon the data transmitted from the sensors. However, the feasibility can be maintained only when the delivered data are fairly reliable without any damage. Since data error is not an uncommon event in wireless sensor networks, the validity of the decision making strongly depends upon the stableness of the data analysis...
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...
Reliable data transfer (RDT) is one of the key issues in wireless sensor networks (WSNs) and can be achieved by using link-level re-transmissions and multi-path routing. Another key issue is the scalability of WSNs. In this paper, we try to better understand and characterize/quantify the relationships between reliability and scalability, and identify possible design options for the future RDT protocols...
According to the particular demand of precision attack effectiveness evaluation (PAEE) system for the protocol of wireless sensor networks and on the base of the studying of robustness properties of wireless sensor networks and flooding protocol, we designed a double parents and reliable protocol (DPRP). This protocol defined level value and parent node, and limited spread scope of the data message...
The congestions in wireless sensor networks have two types: link congestion and node congestion. The primary method for congestion avoidance is to control sending rate, through the mechanism of distribution rate and cache notification. Multi path is the primary method for guaranteeing transmission reliability in wireless sensor networks. Aiming at the node congestion, MPCN-multi path based on cache...
Many applications in Wireless Sensor Networks require collecting all data without loss from nodes. End-to-End data retransmission, which is used in the Internet for reliable transport, becomes very inefficient in Wireless Sensor Networks, since wireless communication, and constrained resources pose new challenges. We look at factors affecting reliability, and search for efficient combinations of the...
