Design And Performance Evaluation Of An Adaptive Geographic Routing Framework For Reliable And Efficient Communication In Multi-Radio Mobile Ad Hoc Networks

Abstract

Mobile Ad Hoc Networks (MANETs) with multiple radio interfaces are emerging as a promising communication technology for military and battlefield applications, where reliable and efficient data transmission is essential. This paper presents a novel geographical routing protocol for heterogeneous multi-radio, multi-band tactical MANETs. The proposed protocol utilizes three radio interfaces, namely IF0, IF1, and IF2, with each interface operating on a different frequency band. Multiple routing metrics are considered to dynamically select the most suitable interface and next-hop node according to network conditions and traffic requirements. The geographical information of neighboring nodes is also utilized to improve packet forwarding toward the destination. The proposed protocol is implemented and evaluated using the JProwler simulation platform, with Java Swing programming developed using NetBeans IDE on the Windows operating system. The simulation results demonstrate that the proposed approach improves communication reliability, routing efficiency, and Quality of Service (QoS) compared with conventional GPRS-based communication. The proposed protocol therefore provides an effective approach for reliable and adaptive communication in dynamic heterogeneous multi-radio tactical MANET environments.
