Due to the wide application fields, many people research Wireless Sensor Networks(WSNs). Currently, more and more researchers focus on the existence of selfish nodes which do not cooperate in routing and forwarding. Traditional methods need too much resource or do not adapt to menace from inner of network. In this paper, we propose a reliable routing model against selfish nodes. Game theory is used...
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...
In this paper, the concept of multi-radio sensor networks is introduced, and the reliability for multi-radio MAC protocol is researched extensively, via establishing a probability model of reliability. To be specific, the reliability of MAC protocols for multi-radio nodes are studies from single-hop and multi-hop, respectively. Furthermore, the upper and lower bounds of these reliabilities are provided...
