-Mobile Ad-hoc Network (MANET) is a wireless network with no infrastructure, used in vital places such as battle fields, disaster areas, remote areas etc. This emergency aiding network is formed ondemand by mobile nodes to accomplish communication and information sharing activities. Since there is no centralized control to oversee the ongoing activities, each node operates with the responsibili...

In Intelligent Transport Systems, traffic management and providing stable routing paths between vehicles using vehicular ad hoc networks (VANET's) is critical. Lots of research several techniques a long path lifetime have been presented to resolve this issue. However, the algorithms suffer excessive overhead or collisions when solving complex optimization problems. order improve efficiency perf...

Geographic routing protocols show good properties for Wireless Sensor Networks (WSN). They are stateless, local and scalable. However they require that each node of the network is aware of its own position. While it may be possible to equip each node with GPS receiver, even if it is costly, there are some issues and receiving a usable GPS signal may be difficult in some situations. For these re...

The Vehicular Ad Hoc Network (VANET) is a promising new paradigm in the domain of wireless communication employed specially for providing road safety, comfort and convenience to the driver as well as passengers while on the way by the integration of various wireless network technologies, cellular technologies like 2G and 3G, sensors, GPS, Bluetooth etc. Due to higher mobility of nodes (vehicles...

A Mobile Ad Hoc etwork (MA ET) comprises mobile nodes, equipped with wireless communications devices; which form a temporary communication network without fixed network infrastructure or topology. The characteristics of MA ET are: limited bandwidth; limited radio range; high mobility; and vulnerability to attacks that degrade the signal to noise ratio and bit error rates. These characteristics ...

Data delivery of packets in broad cast using wireless medium is the main intention of this paper, this will be done through a MANETS and should achieve reliable delivery. To do this various protocols are available in the networks world with in that efficient protocol called Position based opportunistic routing protocol which hold stateless property of geographic routing. When a data packet is s...

Existing position-based routing algorithms, where packets are forwarded in the geographic direction of the destination, normally require that the forwarding node knows the positions of all neighbors in its transmission range. This information on direct neighbors is gained by observing beacon messages that each node sends out periodically. Several beaconless greedy routing schemes have been prop...

Vehicular Ad-hoc Networks (VANETs) where vehicles are described as the moving nodes, is a subclass of Mobile Adhoc Networks (MANETs) in which moving nodes has the potential of self-organization without need of fixed infrastructures. VANET provides road safety, traffic control management and spreading the important information to drivers of the moving vehicles in highly mobile environments. Vari...
