ABSTRACT

A new routing algorithm called position based hybird 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 algorithum are to extend battery life and single strength or power level of the mobile divices by reducing number the required number of operations for route dertermination and to reduce the amount of memory used. although in the (PBHRA) some features of both table driven and on demand algothum were used to achieve these goals at some stages. (PBHRA) algorithm is a complitely different approach in term of position information usage and global positioning system (GPS)
