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...

Future wireless ad hoc networks will use mobile routers to provide Internet connectivity to mobile ad hoc users. A mobile router also allows mobility of an entire ad hoc network, e.g. in plains, trains, cars, and other vehicles, where mobile users may use an Internet access within an ad hoc network domain. Mobile Internet access is also required for various mobile networks such as Personal Area...

Deployed in 1990’s, Mobile Ad-hoc networks have been widely researched for many years. Mobile Ad-hoc Networks are a collection of two or more devices equipped with wireless communications and networking capability. These devices can communication with other nodes that immediately within their radio range or one that is outside their radio range. For the later, the nodes should deploy an interme...

By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...

An ad hoc wireless network is a collection of wireless mobile nodes that self-configure to construct a network without the need for any established infrastructure or backbone. Ad hoc networks use mobile nodes to enable communication outside wireless transmission range. Due to the absence of any fixed infrastructure, it becomes difficult to make use of the existing routing techniques for network...

The IEEE 802.11 MAC protocol is the standard for wireless LANs; it is widely used in testbeds and simulations for wireless multihop ad hoc networks. However, this protocol was not designed for multihop networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc network, in which multihop connectivity is one of the most prominent f...

Mobile ad hoc networks are growing in popularity due to the explosive growth of modern devices with wireless capability such as laptop, mobile phones, PDA, etc., makes the application more challenging. The mobile nodes are vulnerable to security attacks. Providing security and anonymity to users are critical in wireless ad hoc networks. Ad hoc networks have lots of applications; however, a vita...

Ad-hoc networks are a key in the evolution of wireless networks. Ad-hoc networks are typically composed of equal nodes, which communicate over wireless links without any central control. Ad-hoc wireless networks inherit the traditional problems of wireless and mobile communications, such as bandwidth optimisation, power control and transmission quality enhancement. In addition, the multi-hop na...
