In this paper, we develop a performance modeling technique for analyzing the time varying network layer queue-ing behavior of multihop wireless networks with constant bit rate traffic. Our approach is a hybrid of fluid flow queue-ing modeling and a time varying connectivity matrix. Network queues are modeled using fluid-flow based differential equation(More)
—Multihop wireless networks are frequently subjected to nonstationary phenomena due to dynamic network topology. However, the discrete event simulation normally uses the steady-state statistical analysis to study the performance of this type of networks, even though transient or nonstationary period will occur often and likely dominant the network behavior.(More)

Abstract—In this paper, we develop a performance modeling technique for analyzing the time varying network layer queuing behavior of multihop wireless networks with constant bit rate (CBR) traffic.(More)
In the field of tissue engineering, polymeric materials with high biocompatibility like polylactic acid and polyglycolic acid have been widely used for fabricating living constructs. For hypopharynx tissue engineering, skeletal muscle is one important functional part of the whole organ, which assembles the unidirectionally aligned myotubes. In this study, a(More)
