摘要：Mobile ad hoc networks (MANETs) are autonomously self-organized networks without infrastructure support. In a mobile ad hoc network, nodes move arbitrarily; therefore the network may experience rapid and unpredictable topology changes. Because nodes in a MANET normally have limited transmission ranges, some nodes cannot communicate directly with each other. Hence, routing paths in mobile ad hoc networks potentially contain multiple hops, and every node in mobile ad hoc networks has the responsibility to act as a router. A new routing algorithm called position based hybrid routing algorithm (PBHRA) was developed to optimize bandwidth usage of ad hoc networks. The main goal of PBHRA is effective use of bandwidth by reducing the routing overload. Additionally, the other goals of the algorithm are to extend battery life and signal strength or power level of the mobile devices by reducing the required number of operations for route determination and to reduce the amount of memory used. Although in the PBHRA, some features of both table driven and on-demand algorithms were used to achieve these goals at some stages, PBHRA algorithm is a completely different approach in terms of position information usage and global positioning system (GPS).
