An ad hoc wireless network is a collection of wireless mobile nodes that establish some kind of coordination among them to form a network. In ad hoc networks, all nodes share a single radio channel. Therefore, nodes that are within radio distance of other nodes can directly connect with each other [1]. Mobility increases the difficulty of communications among nodes due to variable radio channel...

Mobile ad hoc network (MANET) is characterized as a dynamic, multi-hop wireless self-organized distributed ad hoc network. Because of node mobility and power limitation, the network topology changes frequently which leads to path breakage. Hence a dynamic routing protocol is required for ad hoc networks to function properly. Reactive on -demand routing protocols becomes very popular because it ...

mobile ad hoc networks (manet) are constructed by mobile nodes without access point. since manet has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. the olsr protocol is an optimization of the classical link state algorithm. olsr introduces an interesting concept, the multipoint r...

The Internet has become ubiquitous and there has been tremendous growth in wireless communications in recent years. Many wireless communication techniques are commercially available, such as the Wireless LAN, Bluetooth, GSM, GPRS and CDMA. Because an all-IP network will be a trend, access to the Internet via wireless communication devices has become an important issue. To reduce power consumpti...

Energy efficient broadcast is indispensable for many applications in wireless ad hoc networks. It has been proved that network coding has great potential to improve performance in terms of energy consumption in wireless ad hoc networks. However, the power of network coding depends on the availability of coding opportunities, which in turns depends on how routing paths are established. It is thu...

As the popularity of mobile devices (MDs) and wireless networks significantly increased over the past years, wireless ad hoc networks has now become one of the most vibrant and active fields of communication and networking research. A MANET (Mobile Ad-hoc Network) is a collection of wireless nodes that can dynamically form a network to exchange information without using any preexisting fixed ne...

The IEEE 802.11 medium access control (MAC) protocol is a standard for wireless LANs, it is also widely used in almost all test beds and simulations for the research in wireless mobile multi-hop ad hoc networks. However, this protocol was not designed for multi-hop networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc networ...

Vehicular Ad Hoc Network (VANET) has been drawing interest among the researchers for the past couple of years. Though ad hoc network or mobile ad hoc network is very common in military environment, the real world practice of ad hoc network is still very low. On the other hand, cloud computing is supposed to be the next big thing because of its scalability, PaaS, IaaS, SaaS and other important c...

There has been growing general interest in infrastructureless or “ad hoc” wireless networks recently as evidenced by such activities as the MANET (Mobile Ad hoc NETworking) working group within the Internet Engineering Task Force (IETF). Other examples are plans unveiled for NASA’s Earth orbit satellite constellation networks, and the Mars network, consisting of a “web” of satellites, rovers, a...

This paper discusses the role of ad hoc networking in future wireless communications. Ad hoc networks are'classified as isolated ad hoc networks with large and small sizes, integrated ad hoc networks in various scenarios and cellular ad hoc networks for the future mobile access networks. The very low traffic performance of large scale ad hoc networks is shown by simulation results, indicating s...
