This paper investigates the interworking between wireless ad hoc networks and the Internet. In other words, we consider access to the Internet via a multihop wireless network. The heterogenous communication is established with the help of specific access routers, which serve as gateways between the two kinds of networks. We describe the network scenario and its basic protocol architecture. The ...

A wireless ad hoc network is a decentralized type of wireless network. It is a type of temporary computer-tocomputer connection. It is a spontaneous network which includes mobile ad-hoc networks (MANET), vehicular adhoc networks (VANET) and Flying ad-hoc networks (FANET). A MANET is a network that has many free or autonomous nodes often composed of mobile devices that can operate without strict...

Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...

Mobile Ad Hoc Network (MANET) is a collection of two or more devices or nodes or terminals with wireless communications and networking capability that communicate with each other without the aid of any centralized administrator also the wireless nodes that can dynamically form a network to exchange information without using any existing fixed network infrastructure. And it’s an autonomous syste...

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 (MANET), is a self-configuring network of mobile devices connected by wireless links. The Ad hoc networks are a new wireless networking paradigm for mobile hosts. Wireless adhoc network is autonomous, infrastructure less and may be mobile depending on its type of application. Secure transmission of information in wireless adhoc environment is an important concern. In thi...

Mobile ad hoc networking has been a fast growing research area for the last few years. The need for a network when there is no fixed infrastructure is no more limited to military and emergency applications; ad hoc networks can include private and public applications as well. In ad hoc networks, wireless mobile computing devices can perform critical network topology functions that are normally t...

The evolution and existence of stable trust relations have been studied extensively in the context of social theory. However, reputation systems or trust schemes have only been recently used in the domain of wireless ad hoc networks. It has been shown that these schemes provide positive results as a self-policing mechanism for the routing of data in wireless ad hoc network security. This paper ...

– In MANET, ad hoc network is an energetic topology, hosts, and infrastructure less multi-hop wireless ad hoc environment. The efficient node-energy consumption in wireless ad hoc networks is essential as ad-hoc nodes operate with limited battery power. Thus, failure of node in ad hoc network leads to loss of communication in the network and down frequently due to mobility of nodes. It maintai...
