Wireless technologies such as GPRS, Wi-Fi, Home RF, and Bluetooth make it possible to access the web from mobile phones, print documents from PDAs, and synchronize data among various office devices. However, such applications rely at some point on mobility support routers or base stations, and it is often necessary to establish communication when the wired infrastructure is inaccessible, overloaded, damaged, or destroyed. Mobile ad-hoc networks (manets) remove this dependence on a fixed network infrastructure by treating every available mobile node as an intermediate switch, thereby extending the range of mobile nodes well beyond that of their base transceivers. Other advantages of manets include easy installation and upgrade, low cost and maintenance, more flexibility, and the ability to employ new and efficient routing protocols for wireless communication. In this paper the authors present four manet routing algorithms along with a hybrid approach, their advantages and disadvantages.
