Although extensive efforts have already been devoted to providing optimization based distributed congestion elusion strategy for efficient bandwidth utilization and fair allocation in both wired and wireless networks,a common assumption therein is the fixed link capacities,which will unfortunately limit the application scope in mobile ad hoc networks where channels keep changing. In this paper,an effective congestion elusion strategy is presented explicitly based on ant colony algorithm for mobile ad hoc networks, which will explore the optimal route between two nodes promptly,meanwhile forecast congestion state of the link. Accordingly,a new path will be found rapidly to have the flow spread around to relieve the congestion degree. Compared with OLSR,the strategy proposed will greatly reduce the packet loss ratio and the average end-to-end delay at the same time,which illustrate that it will make use of networking resource effectively.展开更多

In 1978 Kan and Dozy described the first useful restriction fragment length polymorphism (RFLP) in the β globin gene cluster which was found to be in disequilibrium strongly associated with the sickle cell anemia gene (Hb S). Based on that, they did the linkage analysis for Hb S gene and successfully made prenatal diagnosis. From then on, as genetic markers, RFLPs have been widely used for the linkage analysis and the diagnosis of genetic disorders. In 1983 oligonucleotide hy-展开更多
