We propose an improved protocol based on Ad hoc On-Demand Distance Vector Routing (AODV) to adapt to the features such as energy limited and frequent topology changes in Wireless Sensor Networks (WSN). Based on the residual energy and communication load of each node, this protocol creates some routes from the source node to destination node, and then(More)
Software Defined Network is a network architecture where network control is decoupled from forwarding plane and is directly programmable. Control plane monitors data plane's behavior and retrieves an integrated view of data plane. Comparing with classic RSVP based Integrated Services, Decoupled control plane provides a new access to End-to-End guarantee QoS(More)
Wormhole switching technology is widely used in High Performance Computer (HPC) systems. The delay estimation of wormhole switching is mainly focused on average packet delay. But in order to provide Quality of Service (QoS) guarantees, we should analyze the end-to-end delay bound of wormhole switching. Based on models of Credit Stall and Switch Allocation(More)
Optical Interconnection technology has been extensively studied by researchers. Most of these researches mainly focus on the design and optimization of optical devices and system architecture. But, little effort is taken in performing systematic modeling and performance analysis in mathematics. In this paper, we propose a performance analysis model for(More)
