Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...

This thesis develops new routing methods for large-scale, packet-switched data networks such as the Internet. The methods developed increase network performance by considering routing approaches that take advantage of more available network resources than do current methods. Two approaches are explored: dynamic metric and multipath routing. Dynamic metric routing provides paths that change dyna...

The wireless sensor network is rapidly growing field as many sensor manufacturers are focusing on technological research and improvements in wireless sensing technology. Recent advances in wireless sensor network have led to many new protocols specifically designed for routing to reduce energy consumption, increase life time of sensor network, reduce overhead and so on. Routing protocols are di...

This paper describes and evaluates how confidence values can be used to improve the quality of exploration in Q-Routing for adaptive packet routing in communication networks. In Q-Routing each node in the network has a routing decision maker that adapts, on-line, to learn routing policies that can sustain high network loads and have low average packet delivery time. These decision makers mainta...

Today, information networks play an important role in supply chain management. Therefore, in this article, clustering-based routing protocols, which are one of the most important ways to reduce energy consumption in wireless sensor networks, are used to optimize the supply chain informational cloud network. Accordingly, first, a clustering protocol is presented using self-organizing map neu...

Network on Chip (NoC) has been proposed as a good solution to achieve better performance and higher efficiency in today's complex systems on chip. Routing in the NoC is a most important challenge. Final performance of NoC largely depends on the underlying routing scheme. In this paper we evaluate three most efficient routing algorithm namely XY, odd-even and DyAD in 2Dmesh network by different ...

For existing hierarchical network, the network is partitioned into smaller networks where each level is responsible for its own routing but no security and flow control mechanisms has been provided while routing the information, i.e. there is no investigation of ensuring security for hierarchical network routing. Hierarchical routing is used in internet routing such as OSPF. This paper proposes...

Quality-of-Service routing satisfies performance requirements of applications and maximizes utilization of network resources by selecting paths based on the resource needs of application sessions and link load. QoS routing can significantly increase the number of reserved bandwidth sessions that a network can carry, while meeting application QoS requirements. Most research on QoS routing to dat...
