Mobile ad hoc networks, on the other hand, do not have such a centralized entity able to carry out this function. In wired or wireless networks with an infrastructure, there is a server or node which correctly assigns these IP addresses. The TCP/IP protocol allows the different nodes from the network to communicate by associating a distinct IP address to each node of the same network. The nodes of a network need some mechanism to interchange messages with each other.

Finally, Section 6 of the paper draws together the conclusions of this piece of work.Ģ. Auto-Configuration in Mobile Ad Hoc Network Then, in Section 5, a comparative study of the above-mentioned protocols is performed. In Section 4, a classification of auto-configuration protocols for mobile ad hoc networks is carried out, with the most representative being mentioned, and special emphasis being made on a protocol proposed by the author: D2HCP.

Section 3 discusses the inapplicability of the standard solutions. Section 2 tackles the problematic implications of the design of auto configuration protocols for mobile ad hoc networks. This paper is organized into six sections, including this introduction. From the perspective of the IP layer, an ad hoc network presents itself as a multi-hop level 3 network constituted by a collection of links. The ad hoc nodes may also need to set global routing addresses to communicate with other devices on the Internet. To communicate with each other the ad hoc nodes need to configure their interfaces with local addresses which are valid within the ad hoc network. Finally, the limited resources of the nodes must be taken into account given that an ad hoc network will normally be formed by battery operated devices. Moreover, variations in the capacity of nodes and links, frequent transmission errors and a lack of security may occur. The topology of mobile networks may change quickly and in an unpredictable way. Such networks have more problems and disadvantages than a conventional network. In contrast with conventional networks, a MANET does not need any previous infrastructure, since nodes rely on each other to operate themselves, forming what is called multi-hop communication. A Mobile Ad hoc NETwork (MANET) is a set of mobile nodes which communicate between themselves through wireless links.
