This paper presents a novel reactive location routing algorithm based on cluster-based flooding for use in Vehicular Ad-hoc Networks (VANET). We compare position-based and non-positionbased routing strategies in two typical traffic scenarios: urban and motorway. The mobility of vehicles using a microscopic traffic model developed in OPNET is used to evaluate the performance of the reactive Loca...

The paper presents a novel proactive algorithm to routing called Probabilistic Ant Routing, in mobile ad hoc networks, which is inspired by Ant Colony Optimization (ACO) framework and uses “ants” for route discovery, maintenance and improvement. The algorithm is based on a modification of the state transition rule of ACO routing algorithm that results in maintaining higher degree of exploration...

Position based routing algorithms use the knowledge of the position of nodes for routing of packets in mobile ad-hoc networks. Previously proposed position based routing algorithms may fail to find a route from a source to a destination in some types of ad-hoc networks and if they find a route, it may be much longer than the shortest path. On the other hand, routing algorithms which are based o...

A wireless mesh network is a self organized set of nodes that are connected by wireless links. Communicating parties that are not in wireless range of each other relay packets via intermediate nodes. A common approach to wireless mesh routing is reactive routing, where a fixed path between the communicating endpoints is established on-demand when a new session is initiated. This paper proposes ...

In path planning Problems, a complete description of robot geometry, environments and obstacle are presented; the main goal is routing, moving from source to destination, without dealing with obstacles. Also, the existing route should be optimal. The definition of optimality in routing is the same as minimizing the route, in other words, the best possible route to reach the destination. In most...

Mobile Ad-hoc networks (MANETs) are a wireless network without any centralised infrastructure. The routing protocols are used in finding feasible path between source and destination. Two main routing protocol techniques are Proactive and Reactive. Proactive routing protocol maintains routing table for every node in the entire network. Reactive protocols use route information only when required....

The routing in Mobile Ad hoc Network (MANET) is a critical task due to dynamic topology. Many routing protocols were proposed which are categorized as proactive and reactive routing protocols. Route maintenance is a great challenge in MANET due to frequent link failure which causes high data loss and delay. To counter such problems, lots of link repair mechanisms were proposed, but all these ha...

establishing a network of transit routes with satisfactory demand coverage is one of the main goals of transitagencies in moving towards a sustainable urban development. a primary concern in obtaining such anetwork is reducing operational costs. this paper deals with the problem of minimizing construction costsin a grid transportation network while satisfying a certain level of demand coverage....

Mobile Ad hoc Networks (MANET) are characterized by multi hop wireless connectivity, infrastructure less environment and frequently changing topology. Wireless links in MANET are highly error prone and can go down frequently due to mobility of nodes. Most reactive routing protocols do not maintain routing information at the node, on link failure typically a route error message is sent to the so...

-A mobile ad hoc network (MANET) is a continuously self-configuring, infrastructure-less network of mobile devices connected without wires. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET ...
