MIKBIT- Modified DSR for MANET

摘要

Various reactive and proactive routing protocols are being used in Mobile ad hoc networks (MANETs). Dynamic Source Routing (DSR) is one of the reactive routing protocols but high overhead involved in flooding while route creation is a limiting factor of DSR protocol. The paper aims to minimize the number of route requests (RREQs), which is a significant source of overhead for the DSR. In this paper, the modification of DSR algorithm is done to enhance its performance. In the proposed modified DSR i.e. Mobile internetwork broadcast infrastructure technique (MIKBIT) multicasting approach is used to reduce packet overheads. The considered network is IEEE 802.15.4, which is the emerging next generation wireless standard designed for low-rate wireless personal area networks (LR-WPAN). The performance parameters such as throughput, average end-to-end delay, average jitter and packet delivery ratio are evaluated for the proposed algorithm and compared with that of existing DSR routing protocol. Substantial improvement is achieved using the proposed algorithm.
