Mobile Ad hoc networks (MANETs) have several advantages compared to traditional wireless networks. These include ease of deployment, speed of deployment and decreased dependency on a fixed infrastructure. There have been many studies done in this area to improve the quality and efficiency of the routing protocols in MANETs. However unique characteristics of MANETs topology such as open peer-to-...

With the continuing advances in computing and wireless technologies, Mobile Ad Hoc networks (MANETs) are expected to become an indispensable part of the computing environment in the near future. Wireless devices are constantly growing in computing speed, memory, communication capabilities and features, while shrinking in weight and size. With this growth and the proliferation of these devices i...

Over the past decade or so, there has been rapid growth in wireless and mobile applications technologies. More recently, an increasing emphasis has been on the potential of infrastructureless wireless mobile networks that are easy, fast and inexpensive to set up, with the view that such technologies will enable numerous new applications in a wide range of areas. Such networks are commonly refer...

Anonymous Communication is a critical issue in case of mobile ad-hoc networks (MANETs). It is very tough to learn the source and destination of the communication link and the other intermediate nodes that are involved in the communication. Many techniques are proposed to improve the anonymous communication in case of MANETs. However, MANETs are vulnerable under certain situations like passive a...

Millions of people nowadays have portable computers and they generally want to read their e-mail and access their normal file systems wherever in the world they may be. This demand for mobility has fueled the rapid progression of computer & communication technologies from networks consisting of both stationary hosts & routers, to networks consisting of mobile hosts and stationary routers, and m...

Mobile Ad Hoc Networks (MANETs) are wireless networks in which the mobile nodes exchange information without the help of any predefined infrastructure. In such networks also called spontaneous networks, the nodes collaborate to provide the basic network services. Due to their communication type and resources constraint, MANETs are vulnerable to diverse types of attacks and intrusions. One of th...

This thesis is divided into two parts. The first part explores the difficulties of bootstrapping and maintaining a security infrastructure for military Mobile Ad Hoc NETworks (MANETs). The assumed absence of dedicated infrastructural elements necessitates, that security services in ad hoc networks may be built from the ground up. We develop a cluster algorithm, incorporating a trust metric in t...

One of the main characteristics of Mobile Ad-hoc NETworks (MANETs) is high mobility and unpredictable movement nodes. Some times one or more nodes enter to or exit from the network in an instance. In some other cases one or more nodes move from its own place to another place. Everything is influenced by these moving natures in the network which consequently causes some problems for the manageme...

As a result of lower initial investment, greater portability, and operational expenses, wireless networks are rapidly replacing their wired counterparts. The new technology that is on the rise Mobile Ad-Hoc Network (MANET), which operates without fixed network infrastructure, can change its topology fly, requires no centralised administration to manage individual nodes. result, MANETs must focu...

The world is shrinking and one such reason for it is the mobile technology. With the increase in mobiles even the number of nodes in the Mobile Ad-hoc Networks (MANETs) has to be increased. The MANETs are dynamic in nature and this initiates issues in determining the best possible route for the packets. Moreover the packets may face excess traffic and congestion in
