Guiding vehicles to their destination under dynamic traffic conditions is an important topic in the field of Intelligent Transportation Systems (ITS). Nowadays, many complex systems can be controlled by using multi agent systems. Adaptation with the current condition is an important feature of the agents. In this research, formulation of dynamic guidance for vehicles has been investigated based...

The dynamics of an ad hoc network are a challenge to protocol design because mobility of nodes leads to unstable routing, and consequently flows encounter fluctuations in resource availability on various paths during the lifetime of a session. This has become serious, especially for those protocols based on single-path reservation, as frequent reservation and restoration of reservation-based fl...

The specific features of mobile ad hoc networks (MANETs) impose new requirements for routing protocols. The aim of this paper is to present an approach that enhances routing performance by integrating ad hoc related characteristics. We propose a loop-free adaptive path energy conserving scheme which attempts to minimize both routing and storage overhead in order to efficiently provide robustnes...

We study Quality-of-Service (QoS) routing schemes that make routing decisions based on empirical resource availability probability information. These empirical probability based routing schemes offer better performance than traditional schemes that make routing decisions based on resource availability information when the global network state information is imprecise. We investigate variations ...

Mobile Ad Hoc Networks (MANETs) are receiving a significant interest and are becoming very popular in the world of wireless networks and telecommunication. MANETs consist of mobile nodes which can communicate with each other without any infrastructure or centralized administration. In MANETs, the movement of nodes is unpredictable and complex; thus making the routing of the packets challenging....

We present a novel proactive routing algorithm that continuously searches for failures via frequent ICMP echo requests. Our approach differs from its predecessors in that it is proactive instead of reactive. That is, we continuously search for failures before they affect message transmissions. When a failure is detected, an alternative route is identified and used. The Dynamic Routing System (D...

Coupling multiple nodes for high performance transaction processing has become increasingly attractive for reasons of capacity, availability and cost. The shared disks (SD) cluster couples computing nodes via a highspeed network and share a common database at the disk level. This paper proposes a transaction routing algorithm that exploits access affinities of transactions to rationalize worklo...

The future optical Internet based on the Optical Burst Switching (OBS) technology is expected to provision ultra-dynamic bandwidth for multi-custom applications. Data bursts with variable lengths are delivered in the underlying optical layer based on an asynchronous operation mode. Under the framework of OBS routing and signaling, a novel protocol called Domain-based Resource Reservation Protoc...

We propose a novel WDM aware weight function for solving the Routing and Wavelength Assignment (RWA) problem in optical WDM networks taking into consideration factors like number of used wavelengths , availability of free wavelengths and route length jointly under dynamic traffic conditions. The performance of proposed routing strategy is studied in combination with first-fit, and most used wav...

The majority of the existing ad hoc wireless network routing protocols has a tendency to use the shortest single path from the source to the destination. However, in constantly changing topologies such as those in mobile ad hoc networks, the shortest single path is quite unstable for reachability and also for traffic load equilibrium. In this paper, we propose a novel scheme, called Applicative...
