The mobility of nodes may be random and so unpredictable. So the links between the nodes may be unidirectional or bidirectional at times.

List of Acronyms 1. Introduction Traditionally, network routing was concerned with machines and routers connectedtogether by wires. Today network-enabled mobile devices are ubiquitous, so packets arenot only forwarded along fixed paths.

In fact, the line between the wired and mobilenetwork is blurring. Users now expect their mobile devices to seamlessly coexist withtheir wired counterparts. Due to a lack of central base station, nodes in a MANETmust form peering relationships to collectively make routing decisions.

However, these mobile-only protocols attempt to divide a networkwhere clear divisions no longer exist. Assuming a new protocol is everwidely adopted. Another alternative is to support two separate protocols, one for wiredand the other for MANETs, within a single router. However, this complicatesinteroperability between the two networks.

Therefore, the most practical alternative isto extend an existing wired routing standard to support MANETs. OSPF is widely deployed andincludes many innovative features.

The protocol's specifications are in the publicdomain; hence the "open" in OSPF. It is used by upper-tierInternet service providers to determine routes within their networks. It supportsmulticast routing, multiple same-cost paths, and the ability to organize a network as ahierarchy [ Kurose07 ].

Moreover, packet loss frequently occurs on a wirelessmedium due to path loss, interferences, noise, shadowing, and multipath.

It proposes to modify an OSPF-enabled router to connect to both wired and wirelessnetworks. In Section 6,we conclude with a summary. Back to Table of Contents 2.

As shown in Figure 1, a group of routers using the same routingprotocol is collectively referred to as an Autonomous system AS. Upon joining the AS, arouter uses the Hello protocol to discover neighboring routers.

Then it forms adjacencieswith its new neighbors to exchange routing information.Mobile Ad Hoc Networks (MANETs) are an emerging type of wireless networking, in which mobile nodes associate on an extemporaneous or ad hoc basis. MANETs are both self-forming and self-healing, enabling peer-level communications between mobile nodes without reliance on centralized resources or fixed infrastructure.

Persistent Systems, LLC announced that it has entered into a five-year partnership with MartinUAV, LLC. MartinUAV will incorporate Persistent’s Wave Relay Mobile Ad Hoc Network (MANET) technology into the V-BAT, a small vertical takeoff-and-land (VTOL) unmanned aerial vehicle (UAV).

Mobile ad hoc network - Wikipedia

Definition of Mobile Ad-hoc NETwork (MANET): A type of wireless network, made of a self-configuring network of mobile devices. These devices are connected by wireless links.

The union of all these devices forms an arbitrary topology. The Mobile Ad-hoc Networking (MANET) Working Group is a chartered working group within the Internet Engineering Task Force (IETF) to investigate and develop candidate standard Internet routing support for mobile, wireless IP autonomous segments.

Wireless communication is established by nodes acting as routers and transferring pack- ets from one to another in ad-hoc networks.
