Review on Localized Demand Driven Routing (LDDR) Protocol

Ad-hoc networks offer an approach for communicating for mobile devices having no need for direct communication for the nodes that are placed internal to the range and midway nodes are utilized to direct messages to the terminal locations more than with a single hop. Ad-hoc networks have been widely used in a variety of applications, including military communications, emergency response, and sensor networks. However, they are also associated with several traditional problems and challenges, including limited range, interference, security, routing and high-cost overhead which prohibit scalability. To overcome these challenges, researchers are actively working on developing new technologies and protocols for ad-hoc networks. For example, some researchers are exploring the use of cognitive radio technology to mitigate interference, while others are working on developing more efficient routing protocols that can handle larger networks. In this paper, we discuss and review a new distributed routing algorithm specifically designed to support highly dynamic networks to minimize the cost overhead and therefore save power.
