Abstract
Mobile ad-hoc network is a collection of mobile nodes. Mobility of the nodes leads to dynamic changes in network topology that may complicate the routing functions. Earlier a variety of topology and position-based routing protocols have been proposed for routing process in MANET. The results reveal that the position-based routing protocols are the better choice for routing functions in comparison with topology-based routing protocols. Therefore, our study is motivated to work for position-based routing so it enhances the performance of network. The proposed protocol aims to reduce the possibility of collisions, delay and decrease the overall communication overhead in network. Hence our scheme first, defines a small triangular shaped requested zone broadcast region which is dynamic in nature. Secondly, fuzzy-based forwarding scheme is proposed which combines both distance and directionbased strategies to determine the next forwarding node to achieve better performance with regard to energy consumption, routing overhead and end-to-end delay. The proposed scheme also focuses on the hole problem in the request zone and proposes a self-adjustable transmission range-based method to overcome the problem. The simulation results show that the proposed scheme outperforms than LAR1 and LARDAR schemes.
