Routing is the primary element of an ad-hoc network. It takes routing software in each network node to manage the transfer of IP packets. The simplest solution is obviously to have a direct routing, as illustrated in Figure, in which each network station can directly reach another station, without going through an intermediary. The simplest case corresponds to a small cell, with a diameter less than 100 m, as in an 802.11 network in ad-hoc mode.

A Wi-Fi network is made with many amenities, such as access points, antennas, bridges, controllers, etc. In this section, we will make an overview of the equipment in order to provide some features.

The LAP-F protocol (Link Access Protocol-Frame) was born with frame relay, designed to improve the performance of networks from the X.25 recommendation UITT. The latter has proved too heavy and therefore unable to increase rates, it took in search for a simplification.

Ethernet on the WAN aims to transport Ethernet frames over long distances like states, countries, or the whole world, while providing quality service. Its advantages are a very low cost, the possibility of oversizing of the network, highly granular, well known technology and very simple and finally simplified management, since Ethernet is everywhere. You can go very fast in throughput with different levels of 1 and 10 Gbit/s and soon the 100 Gbit/s. The register of difficulties include the lack of reliability, packet loss less controlled and quality of services more difficult to obtain. However, several technologies are currently being developed to address these issues and provide a royal way for the arrival of Ethernet on the WAN.

Applications that are conventionally used on terminal equipment put in implement a point-to-point communication, that is to say the part of the communication micro to go look for information to only one other point. Many other applications involve the cooperation of several processes. For example, a search in a distributed database in which information is spread across multiple sites, uses a simultaneous request for information to several centers. To make this request, the application and all associated protocol layers must manage multipoint. This way of communicating is more powerful than that which is to apply a first site, and once the response, a second, and so on.

Mesh networks (meshed networks) are ad-hoc networks in which routing points are immobile. Customers are connected by a wireless network access points and the access points are connected by wireless links.

After invading the world of business, Ethernet addresses the longer distances starting with the metropolitan area. The Metro Ethernet was born of this extension. This solution is supported in different settings but especially by the Forum MEF (Metro Ethernet Forum).

The local loop is to connect users to the first node, router or switch, the operator with whom the customer has a subscription. Broadband solutions is shared between the ATM for fixed links and Ethernet for wireless backhaul. One of the objectives in the Ethernet local loop is replaced by the ATM Ethernet solutions, particularly in the xDSL modems.

A sensor array is defined as a set of sensors connected to one another, each sensor being provided with a transceiver. Sensor networks are a new generation networks with specific properties, which do not fall within the conventional architectures.

The frame level (layer 2) is to render a service to the next level just. This service is a transport node to node packet. Specifically, its role is to transport a package of three or message fragment layer of layer 4 from one node to another node. For this, the frame level asks his turn at just below, the physical level, a service of conveying the bits of the frame from one node to another node. This section provides the features necessary to achieve all these actions.
