To modify communication between nodes that don't have direct radio contact, every node should operate as a wireless router and potential forward knowledge traffic of behalf of the opposite node. In MANET Localization is a fundamental problem. Current localization algorithm mainly focuses on checking the localizability of a network and/or how to localize as many nodes as possible. It could provide accurate position information foe kind of expanding application. Localization provide information about coverage, deployment, routing, location, services, target tracking and rescue If high mobility among the mobile nodes occurs path failure breaks. Hence the location information cannot be predicted. Here we have proposed a localization based algorithm which will help to provide information about the localized and non-localized nodes in a network. In the proposed approach DREAM protocol and AODV protocol are used to find the localizability of a node in a network. DREAM protocol is a location protocol which helps to find the location of a node in a network whereas AODV is a routing protocol it discover route as and when necessary it does not maintain route from every node to every other. To locate the mobile nodes in a n/w an node identification algorithm is used. With the help of this algorithm localized and non-localized node can be easily detected in respect of radio range. This method helps to improve the performance of a module and minimize the location error and achieves improved performance in the form of UDP packet loss, received packet and transmitted packets, throughput, routing overhead, packet delivery fraction. All the simulation done through the NS-2 module and tested the mobile ad-hoc network. Key words: - MANET, Location aware, Energy, DREAM, Routing, Localization. 1. INTRODUCTION: A network is essentially a group of 2 or a lot of articles that are connected therefore the computers will share resources, like printers, software, and net connections. Networked computers also can share files while not having to transfer knowledge employing a disk or knowledge key. An ad-hoc network can be a assortment of wireless mobile hosts forming a quick network whereas not the assistance of any complete infrastructure or centralized administration. Mobile Ad- hoc networks are self-organizing and self-configuring multi hop wireless networks wherever, the structure of the network changes dynamically. This is often principally as a result of the quality of the nodes. Nodes in these networks utilize an equivalent random access wireless channel, cooperating in an exceedingly friendly manner to participating themselves in multi hop forwarding. The node within the network not solely acts as hosts however conjointly as routers that route knowledge to/from alternative nodes in network. In mobile ad-hoc networks there\'s no infrastructure support as is that the case with wireless networks, and since a destination node can be out of vary of a supply node transmission packets; a routine procedure is usually required to seek out a path thus on forward the packets suitably between the supply and therefore the destination. Within the case of ad-hoc networks, every node should be ready to forward knowledge for alternative nodes. This paper focuses on the localization techniques to identify node location. Several researches are going on in the field of localization to identify the exact location. The location of the nodes plays a significant role in many areas as routing, surveillance and monitoring, military etc. Localization of a sensor node is carried out with the help of neighbouring nodes. The localization techniques can be grouped into two types namely range based and range free approach. A. Range based approach This method uses the range information to calculate the distance between each node. The localization can be carried out with or without the anchor nodes B. Range free approach There are few localization techniques that do not require special hardware for localization. i. Using anchor nodes While deploying the sensor network, few are manually configured their location reference either manually or using GPS. These nodes act as the anchor nodes. Other nodes localize themselves with the support of anchor nodes. ii. Without using anchor nodes
