Wireless ad-hoc networks have gained a lot of importance in wireless communications. Wireless communication is established by nodes acting as routers and transferring packets from one to another in ad-hoc networks. Routing in these networks is highly complex due to moving nodes and hence many protocols have been developed. Mobile ad hoc networks are networks without fixed infrastructure. The mo...

Within the last decade, the use of wireless technologies has become more prevalent. Wireless networks have flexible architectures with data transferred via radio waves and can be divided into two categories; infrastructure-based wireless networks and mobile ad hoc network. The mobile ad hoc network (MANET) is an autonomous system which can be dynamically built without preexisting infrastructure...

A mobile ad hoc network is a collection of autonomous nodes that communicate with each other by forming a multi-top wireless network. Different from conventional wireless networks, the resource of the nodes in ad hoc networks is limited and there may be tens of thousands of low-power energy constrained nodes in ad hoc networks. As such, the costs of the nodes resource and the network size shoul...

An ad hoc network is a dynamically reconfigurable wireless network with no fixed infrastructure or central administration. Each host is mobile and must act as a router. Routing and multicasting protocols in ad hoc networks are faced with the challenge of delivering data to destinations through multihop routes in the presence of node movements and topology changes. This paper presents the On-Dem...

Mobile ad hoc networks (MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad hoc network topologies. A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. The widely accepted existing routing protocols designed to a...

Ad-hoc networks are a key in the evolution of wireless networks. Ad-hoc networks are typically composed of equal nodes, which communicate over wireless links without any central control. Ad-hoc wireless networks inherit the traditional problems of wireless and mobile communications, such as bandwidth optimisation, power control and transmission quality enhancement. In addition, the multi-hop na...

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...

due to limitations in computing resources of mobile nodes, mobile ad-hoc networks (manets) are very fault-prone. so far, redundancy at different levels of the network has been considered an efficient strategy to enhance the fault-tolerance of networks. indeed, ad-hoc networks are extremely redundant; therefore, natural redundancy to fault tolerance enhancement has a great impact on the network ...

In this position paper we argue that applications for the communication between vehicles do not require the functionality typically offered by mobile ad-hoc-networks or wireless sensor networks. Consequently the name Vehicular Ad-Hoc Network (VANET) is a misnomer leading practitioners and researchers astray. In order to make our point we briefly outline the characteristics of Mobile Ad-Hoc Netw...

The IEEE 802.11 MAC protocol is the standard for wireless LANs; it is widely used in testbeds and simulations for wireless multihop ad hoc networks. However, this protocol was not designed for multihop networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc network, in which multihop connectivity is one of the most prominent f...
