摘要

Mobile ad hoc networks (MANETs) are a very active area of research due to their great potential to provide networking capabilities when it is not feasible to have a fixed infrastructure in place or to provide a complement to existing infrastructure. The routing in these networks is more challenging than that of conventional networks due to their mobile nature and limited power and hardware resources. The global mobile information system simulator (Glomosim) simulation environment is used in this study to investigate various statistics and draw comparisons among routing protocols: Bellman-Ford, ad hoc on-demand distance vector (AODV), dynamic source routing (DSR), location-aided routing (LAR), Windows resource protection (WRP), and Fisheye. In particular, we investigate protocol performance used in a military application assuming MANETs used for manpower, tank (e.g., Tl), or helicopter (e.g., MQ-8B) connecting network configurations, but the network configurations for all experiments are generic enough to be applied to other environments. This study encompasses a greater number of routing protocols than most other previous works and investigates, among other things, some effects that are not commonly methodically investigated, including radio range and physical domain aspect ratio. Our results show that with a few exceptions, when varying the number of nodes in the network layout, AODV and LAR outperform other routing protocols for most configurations. For higher node densities at about 70 nodes and above, as the transmit power increases from 7.005 to 10.527 dBm, as expected, all protocols perform better at lower mobility speeds, but AODV and LAR exhibit a much smaller performance degradation when this speed increases.
