Wireless Networking is becoming very popular and interesting technology especially in these days as everyone wants wireless connectivity at anywhere anytime. It contains numerous wireless network technologies such as WiFi, WiMax, HSDPA and WiBro etc. Based on structural arrangement, wireless networks are categorized into two main categories: fixed infrastructure wireless networks and infrastruc...

The advent of ubiquitous computing and the proliferation of portable computing devices have raised the importance of mobile and wireless networking. At the same time, the popularity of group-oriented computing has grown tremendously. However, little has been accomplished to-date in bringing together the technologies for group-oriented communication and mobile networking. In particular, most mod...

A Mobile Ad hoc NETwork (MANET) is a kind of wireless ad-hoc network, and is a self configuring network of mobile routers (and associated hosts) connected by wireless links – the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the network's wireless topology may change rapidly and unpredictably. Such a network may opera...

With the current increase in ad-hoc mobile networks in public domains (e.g. airports, cities, etc.), and the widespread use of the IEEE 802.11 standard in wireless LAN, there is a growing need to handle and manage fast mobility. Optimized Link State Routing protocol (OLSR) is a proactive protocol that enables routing in Mobile Ad-hoc NETworks (MANETs). Fast-OLSR is a new extension of OLSR desig...

Wireless network consist of wireless node without any administration. Due to present of mobility of nodes, the network is easily personated by several attacks. In 1980’s Mobile ad hoc network s have been widely researched ` for many years. Ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies .The infrastructure less and dynamic ...

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...

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...

In mobile wireless environments, personal digital assistants may cache data to work even when the mobile client is far from the structured network. However, the same cached data may be shared by two or more users and this can be done in an ad-hoc wireless network. In this case, it is necessary to have always the most updated data. To solve this problem, we developed a software that share data b...

Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, ‘‘ad-hoc’’ network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Ad hoc networking concept is no...
