Efficiently routing in a dynamic network is a important problem in ad hoc network according to development of personal data assistant (PDA) and wireless network equipment. However conventional routing algorithm is difficult to apply to dynamic topology network. Q-Routing, DRQ-Routing and Ants-Routing which are based on reinforcement learning technique are proposed. But convergence speed and rou...

muskingum-cunge is one of the widely employed methods for flood routing. direct calibration of the model based on previous flood events is not required and the routing parameters in this method are determined according to physical characteristics and hydraulic conditions of the stream. during the last decade, different modifications were proposed for the method to increase its accuracy. in this...

Recently, shortest path tree construction is essential in network routing. Dijkstra algorithm, one of the static routing algorithms, is widely used. When some links develop new weights, dynamic routing algorithms become more efficient than static routing algorithms. This is because dynamic routing algorithms reduce the redundancy caused by re-computing the affected part of the network in regard...

flood routing has many applications in engineering projects and helps designers in understanding the flood flow characteristics in river flows. floods are taken unsteady flows that vary by time and location. equations governing unsteady flows in waterways are continuity and momentum equations which in case of one-dimensional flow the saint-venant hypothesis is considered. dynamic wave model as ...

Cognitive Radio (CR) is a promising technology which deals with using vacant spectrum of licensed frequency band opportunistically. In CR Network, route construction must not affect the transmission of Primary User activity. In CR technology challenge of maintaining optimal routes arises due to PU activity and mobility of spectrum resources i.e. CR users. Maintaining optimal routes in Ad-hoc CR...

This paper proposes a novel scheme of Fuzzy Logic based dynamic routing in computer networks. The proposed dynamic routing algorithm is suited for application in Interior Gateway Protocols (IGP) inside an autonomous system (AS), such as a Local Area Networks (LAN). It is used in the protocols to find out a set of best possible routes, where each of the nodes broadcasts link status rather than b...

Mobile Ad Hoc network (MANET) is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of pre-established network infrastructure. With the development of network and demand of users, QoS has become one of the focus issues. Some of the routing protocols provide QoS performance; however, more work is required in developing scalable ad hoc...

The cheap and easy availability of wireless devices boosted the MANETs supported applications. Due to these emerging applications MANETs are not only deployed in military sector but in every walk of life. Now QoS assurance to these applications is an essential part rather than additional feature in MANETs. The routing protocols provide only data route rather than assuring any kind of guaranteed...

In this paper, we consider dynamic QoS Routing in an integrated-services environment where some of the offered traffic streams are dynamic. While there has been work on routing performance in the presence of purely stationary traffic, the presence of dynamic traffic has received very little attention. We consider here three routing schemes: Dynamic Random Routing (DRR), Maximum Available Capaci...

As of date, wireless communication is one of the most demanding areas of research within networking, with many proposed, but unverified protocols. The success of the proposed protocols depends on the availability of robust implementations that enable both real-time test beds and non-real time simulations. Wireless ad-hoc network is a collection of mobile nodes forming a temporary network withou...
