Vehicular ad-hoc network (VANET) is an integral component of intelligent transportation systems. Due to continuous movement of vehicles, network formation and deformation is very frequent. Furthermore, for safety applications, we wish to create the communication without any delay or collision. Therefore, communication among the vehicles is even more challenging. D-LAR (Directional– Location Aid...

Vehicular Ad-Hoc networks (VANETs) have been an active research domain during the past few years. Work so far focused on routing and applications, however, research on security issues has been started only recently. One of the fundamental results of past and ongoing research projects in the domain of vehicular ad-hoc networks is the usage of geographic routing protocols. On the one hand this is...

Recently, multicast routing protocols become increasingly important aspect in Mobile Ad hoc Networks (MANETs), as they effectively manage group communications. Meanwhile, multimedia and real-time applications are becoming essential need for users of MANET. Thus it is necessary to design efficient and effective Quality of Service (QoS) multicast routing strategies. In this paper, we address the ...

Traditional topology-based MANET routing protocols use stateful routing which increases the processing, communication and memory overheads. The high mobility of nodes in MANETs makes it difficult to maintain a deterministic route. To overcome this, stateless geographic routing protocols which ensure reliable data delivery have been proposed. It is found that link instability can be a major fact...

Ad hoc networks consist of autonomous self-organized nodes. Nodes use a wireless medium for communication, thus two nodes can communicate directly if and only if they are within each other’s transmission radius. Examples are sensor networks (attached to a monitoring station), rooftop networks (for wireless Internet access), and conference and rescue scenarios for ad hoc networks, possibly mobil...

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Conventional routing protocols in MANETs (Mobile Ad hoc Networks) are unable to fully address the unique cha...

The biggest challenge in MANETs is to find a path between the communication end points, which is aggravated through the node mobility in a limited resource scenario.AntColony-Based Routing Algorithm (ARA) is an on-demand routing algorithm for mobile, multi-hop ad-hoc networks that uses swarm intelligence paradigm and ant colony based meta heuristic. These approaches try to map the solution capa...

All previously proposed position based routing algorithms for wireless ad hoc networks were based on forwarding the actual message along multiple paths toward an area where destination is hopefully located (except our previous report [SV]). In [SV], we proposed to reduce significantly the communication overhead by changing the routing strategy. The source node issues several search 'tickets' (e...

The CarTALK 2000 project [1] aims at the development of new driver assistance systems that are based upon intervehicle communication. To this purpose, a mobile ad hoc network (MANET) consisting of vehicles will be developed as the communication platform to support cooperative driver assistance applications. Routing in such a vehicular MANET faces a number of new challenges, in particular due to...
