An Overview of Mobile Ad Hoc Networks for the Existing Protocols and Applications

Mobile Ad Hoc Network (MANET) is a collection of two or more devices or nodes or terminals withwireless communications and networking capability that communicate with each other without the aid ofany centralized administrator also the wireless nodes that can dynamically form a network to exchangeinformation without using any existing fixed network infrastructure. And it’s an autonomous system inwhich mobile hosts connected by wireless links are free to be dynamically and some time act as routers atthe same time, and we discuss in this paper the distinct characteristics of traditional wired networks,including network configuration may change at any time , there is no direction or limit the movement andso on, and thus needed a new optional path Agreement (Routing Protocol) to identify nodes for theseactions communicate with each other path, An ideal choice way the agreement should not only be able tofind the right path, and the Ad Hoc Network must be able to adapt to changing network of this type at anytime. and we talk in details in this paper all the information of Mobile Ad Hoc Network which include theHistory of ad hoc, wireless ad hoc, wireless mobile approaches and types of mobile ad Hoc networks, andthen we present more than 13 types of the routing Ad Hoc Networks protocols have been proposed. In thispaper, the more representative of routing protocols, analysis of individual characteristics and advantagesand disadvantages to collate and compare, and present the all applications or the Possible Service of AdHoc Networks
