This paper investigates the traffic handling capability of wavelength routed optical WDM (Wavelength Division Multiplexing) network, exploiting multi-path transmission under a proposed adaptive link weight algorithm. Data transmission through multiple paths improves the connection probability by reducing the wavelength hold time on a link. Further it reduces traffic load on bottleneck links by distributing...
An ad hoc network comprises of mobile computing devices that use wireless transmission for communication. It has no fixed infrastructure. The mobile devices also serve as routers. Ad hoc wireless networks can be deployed quickly anywhere and anytime as they eliminate the complexity of infrastructure setup. It finds applications in military communications, emergency operations, hybrid wireless network...
WSNs are multihop networks, which depend on the intermediate nodes to relay the data packet to the destination. These nodes are equipped with lesser memory, limited battery power, little computation capability, small range of communication and need a secured and efficient routing path to forward the incoming packet. In this paper, we propose a secure cluster based multipath routing protocol (SCMRP)...
Genetic Zone Routing Protocol (GZRP), a new multi path routing protocol for MANETs, is an extension of ZRP by using Genetic Algorithm (GA). GZRP uses GA on IERP and BRP parts of ZRP to provide a limited set of alternative routes to the destination in order to load-balance the network and robust when node/link failure occurs during the route discovery process. GZRP is studied for its performance and...
Ad hoc networks are characterized by wireless connectivity, continuous changing topology, distributed operations and ease of deployment. Routing in Ad hoc networks is a challenge due to mobility and thus is a current area of research. We compare two reactive routing protocols by considering multiple performance metrics to bring out their relative merits. Both DSR and AODV share similar on demand behavior,...
An Ad-hoc network is a cooperative arrangement of the collection of mobile nodes without any centralized control. A central challenge in Ad-hoc networks is the design of routing protocols that can adapt its behavior with the frequent and rapid change in the network. The performance of the protocols varies with network characteristics and one protocol outperforms the other in some different network...
Ad-hoc networks may exhibit varying characteristics in different environment, which may make the use of various physical layers, network topologies, and nodal mobility's. Using a simulator it is possible to model and simulate different physical layers, Link / MAC layers, and multi-routing schemes, to compare end-to-end statistics (end-to-end delay, throughput and energy efficiency), andfinally to...
We describe applications of policy-based reasoning algorithms in joint networking, including ground and airborne nodes, and illustrate how this approach can be used to enhance routing, network planning, mission planning, and spectrum allocation for tactical networking data links such as airborne networking waveform (ANW) and wideband networking waveform (WNW). The outcome of this research will be...
