his paper focuses on the problem of implementing a distributed hash table (DHT) in wireless ad hoc networks. Scarceness of resources and node mobility turn routing into a challenging problem and therefore, we claim that building DHT as an overlay network (like in wired environments) is not the best option. Hence, we present a proof-of-concept DHT, called(More)
Emerging ubiquitous computing needs "anytime and anywhere" network connections. Mobile ad hoc networks are well suited for this application area because they are self-organizing networks without depending on any network infrastructure. Due to the improved flexibility and reduced cost of mobile ad hoc networks, they promise to play an important role in(More)
Sixty-eight field isolates of Peronophythora litchii, the causal agent of litchi downy blight, were examined for sensitivity to four novel QoI fungicides (SYP-1620, SYP-2815, ZJ0712 and enestroburin) in vitro with a mycelial growth assay. Ranges and means of EC50 values (in μg/mL) were 0.047–0.288 and 0.138 for SYP-2815, 0.056–0.992 and 0.148 for ZJ0712,(More)
Peronophythora litchii is the causal agent of litchi downy blight. Enestroburin, SYP-1620, SYP-2815 and ZJ0712 are four novel QoI fungicides developed by China. Eight mutants of P. litchii resistant to these QoI fungicides and azoxystrobin (as a known QoI fungicide) were obtained in our preliminary work. In this study, the full length of the cytochrome b(More)
Most of the researches focus on the secure and reliable communications in Mobile ad hoc networks (MANETs) because of the presences of malicious nodes, unreliable wireless media, host mobility and lack of infrastructure. However the basic idea of forming an Ad Hoc network is utilizing the cooperation between nodes which becomes critical to maintain QOS.(More)
Mobile ad hoc network is highly dynamic and distributed in nature hence routing is one of the key issues in it. In particular, designing efficient algorithm for routing may be the most important criteria for MANETs since mobile nodes have limited battery capacity. This results in short continuous operations which is the general constraint in wireless(More)
