The ability to discover services is the major prerequisite for effective usability of MANETs. Group-based Service Discovery (GSD) protocol is a typical service discovery protocol for MANETs. However, because of large redundant packet transmissions, its packet overhead is high. In this paper, in light of GSD, we propose a new service discovery protocol for Mobile Ad-Hoc Networks (MANETs): Candid...

A Mobile Ad Hoc Network (MANETs) connects mobile nodes without any base station. These in the network can change topology dynamically and transfer data among themselves. The MANET are categorized based on resource factors like memory, computation, power levels. dynamic route makes connection of destination node more complex. Sometimes, it results link failure, hence primary is failed, which mea...

A mobile ad hoc network (MANET) is a group of nodes constituting without predefined and pre-established architecture where can communicate any dedicated access points or base stations. In MANETs, node may act as host well router. Nodes in the send receive packets through intermediate nodes. However, existence malicious selfish MANETs severely degrades performance. The identification such their ...

Wireless mobile devices such as high-end cell phones, PDAs, portable gaming devices, tablet PCs etc. all having wireless networking capabilities have a tremendous increase in recent years. These devices when used in Mobile Ad Hoc Networks (MANETs) may extend their capabilities, e.g., to reach the Internet when no Wi-Fi base stations are within range, or to have communication with each other ove...

Internetworking the mobile ad-hoc networks (MANETs) with the Internet has been a hot issue for many years. However, most researches have been concentrated on the use of MANETs as the access networks for the Internet. This paper introduces another use of MANETs: backup or load-balancing transit networks for the Internet. Although the MANETs capacity is currently low compared with other backbone ...

Mobile ad hoc networks are self organizing, infrastructure-less, low power networks, design to deploy bandwidth-shared radio channel communicat ion and to work under vulnerable environment. Security is primary concern in MANETs and in order to achieve high security (confidentiality, integrity, authentication, availability and non repudiation), several techniques have been exp lored in which b i...

Mobile Ad hoc Networks (MANETs) are autonomous mobile node systems connected by wireless links. A node operates as an end system and as a router, to forward packets. MANET routing is challenging and has received tremendous attention from researchers. Dynamic Source Routing (DSR) protocol was accepted as a dominant routing protocol for MANETs. Performance analysis and results show that DSR as an...

Mobile Ad hoc Networks (MANETs) are composed of autonomous mobile nodes with communication capability that is often deployed in an unattended environment, thus leaving them vulnerable. Research concerning in MANETs routing is gaining much attraction because of its never ending improvement. There is no centralized hierarchy in MANETs, so nodes itself behave as routers. The performance of MANET i...

This paper evaluates the performance of a semidistributed multinode time-of-arrival (TOA) and direction-of-arrival (DOA) fusion localization technique in terms of localization circular error probability (CEP). The localization technique is applicable in mobile ad hoc networks (MANETs) when global positioning system (GPS) is not available (GPS denied environments). The localization CEP of the te...

In recent years, the static shortest path (SP) problem has been well addressed using intelligent optimization techniques, e.g., artificial neural networks, genetic algorithms (GAs), particle swarm optimization, etc. However, with the advancement in wireless communications, more and more mobile wireless networks appear, e.g., mobile networks [mobile ad hoc networks (MANETs)], wireless sensor net...
