If Sugar sees no "known" network (the learner has not been connected to an currently available Access Point before) … they should act as a Overview: Wireless Ad hoc networks are networks in which communication links are based on wireless technologies and the network structure or topology is not pre-defined rather build through dynamic network connectivity. Also known as Independent Basic Service Set (IBSS) Allow two or more Wi-Fi clients to connect to each other directly, without a wireless access point; Why am I seeing it? MANET stands for Mobile adhoc Network also called as wireless adhoc network or adhoc wireless network that usually has a routable networking environment on top of a Link Layer ad hoc network.. All nodes have identical features with similar responsibilities and capabilities and hence it forms a completely symmetric environment. A->D->B For multi-hop communication to work, the intermediate nodes should route the packet i.e. Abstract: The distinctive features of mobile ad hoc networks (MANETs), including dynamic topology and open wireless medium, may lead to MANETs suffering from many security vulnerabilities. VANet is a new type of mobile ad hoc network that comprises self-organizing vehicles as mobile nodes. The reliability, efficiency, stability, and capacity of wireless links are often inferior when compared with wired links. Ad-hoc networks are often secured to protect against attacks. Mobile ad hoc networks can be used alone (for example in the military) or as a hybrid together with the Internet or other networks. The three common sub types of these networks are Mobile Ad hoc Networks (MANETs), Wireless Sensor Networks and Wireless Mesh Networks. It is an infrastructure-less IP based network of mobile and wireless machine nodes connected with radio. Classification of routing protocols for MANET is based on how routing information is acquired and maintained by mobile nodes and/or on roles of network nodes in a routing. Internet-based mobile ad hoc networks (iMANETs) is a type of wireless ad hoc network that supports Internet protocols such as TCP/UDP and IP. depicts a peer-to-peer multihop ad hoc network Mobile node A communicates directly with B (single hop) when a channel is available If Channel is not available, then multi-hop communication is necessary e.g. in order to make routing decisions. The nodes are equipped with wireless transceiver. The only connections required are the wireless connections in the devices. It has a limited capacity that it can connect a node to the nearby node to form a network. mesh [mɛʃ] Masche oder Netz). The devices communicate with each other directly instead of relying on a base station or access points as in wireless LANs for data transfer co-ordination. It is capable to establish a fast network with the available set of nodes. Advantages of ad hoc networks The rapid development in ad hoc technology is widely used in portable computing such as laptop, mobile phone used to access the web services, telephone calls when the user are in travelling.

INTRODUCTION Wireless ad hoc networks are collections of wireless nodes, that communicate directly over a common wireless channel. […], why mannet is not still ignored….since it is prone to attack. VANet, which encompasses vehicle-to-vehicle (V2V) and/or vehicle-to-roadside (V2R) communications [12] , has been proposed for enhancing safety (e.g., collision avoidance, traffic optimization, lane-changing assistance) and comfort (e.g., toll/parking payment, Internet access, locating fuel stations) … The network is not dependent upon the common wireless infrastructure which includes routers and access points that is why it is an ad hoc network. MANETs have an additional feature … Limited range of wireless transmission – The limited radio band results in reduced data rates compared to the wireless networks.
