This paper presents a novel QoS support approach for mobile ad hoc networks (MANET). The fuzzy logic is used for QoS management in two phases, first for traffic rate controlling, and then for packet accepting controlling. After using fuzzy logic we used Radial Basis Function Neural Networks (RBFNN), for QoS management. The results show that our new management methods (RBFNN QoS management) not ...

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...

The user anonymity is an important security factor to protect personal privacy in mobile ad hoc networks. Recently, Wu et al. proposed an ad hoc on-demand position-based private routing protocol (AO2P), but the AO2P is vulnerable to some collaborative attacks, such as blackhole & wormhole attacks. Once any compromised node is included in a route, it can conduct different attacks, which are very...

Heretofore several position-based routing protocols have been developed for mobile ad hoc networks. Many of these protocols assume that a location service is available which provides location information on the nodes in the network.Our solutions decrease location update without loss of query success rate or throughput and even increase those.Simulation results show that our methods are effectiv...

Ab8tmct-A mobile ad-hoc network is composed of only mobile nodes, which are distributed dynamically, without any wired backbone or centralized entities. Each terminal in the mobile ad-hoc network also has the role of the router, but the frequent changes of the terminal positions induce the waste of time, energy and computing power for updating the routing table with the paging, and also may pro...

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...

Mobile Ad-hoc Network (MANET) is an autonomous, multi-hop and dynamic network composed of number of wireless mobile nodes. Routing protocols are challenges in designing Mobile Ad-hoc networks with low energy consuming and low control overhead. Ad-hoc on demand distance vector routing protocol (AODV) is specially designed for mobile ad-hoc networks with Expanding Ring Search (ERS) technique for ...

B ECAUSE the subject of this issue is wireless ad hoc networks, it would be beneficial to provide a definition of the phrase ad hoc as it is used in the context of mobile wireless networks. We have as a starting point the common definitions of this phrase, such as " for a specific purpose or occasion " or " for this case alone, " and many of us have served on at least one ad hoc committee. But ...
