This paper presents a novel multipath load balancing algorithm called priority-based adaptive weighting (PAW) for video over software defined networks (SDN). Based on priority differentiation among video packets, PAW adopts a per-packet strategy to distribute ingress video packets over the multiple egress ports of an entry SDN-switch connecting to those output links leading to the same IP destination,...
This paper proposes a cross-layer wireless routing protocol called REAR (Radio Environment Adaptive Routing Protocol), which operates with Cognitive Radio (CR) Mobile Ad Hoc Networks (CRMANET). Unlike conventional on-demand routing protocols for ad hoc networks, the design of REAR allows nodes along the route to adjust the next hop according to real-time radio environment conditions during the transmission...
Flow-Aware Multi-Topology Adaptive Routing (FAMTAR) is a new mechanism which provides the ability to use multiple paths between two points in a network. When the primary path becomes congested, a new path is found and used. However, when all possible paths are congested, new flows are still accepted on one of the congested paths which degrades the observed quality of service. Therefore, in this paper,...
In this article, we propose a general-purpose disaster support system based on generalized (multiplicatively-weighted order-k Minkowski-metric) Voronoi diagrams. The proposed system is capable of handling disasters (or emergency units) having different weights in the complete order from 1 to k in the three popular Minkowski metrics (Euclidean, Manhattan and Maximum distance space). The proposed model...
The Department of Electronic Engineering of Beijing Institute of Technology is integrating emerging interconnect technologies with other high-performance technologies to meet the demanding requirement of future, real-time signal processing applications. For next-generation, scalable, modular and adaptable signal-processing system, a universal, flexible and high-performance signal processing module...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
