Abstract

In MANETs, DSR has been extensively studied since proposed. One of the most significant strategies that improve DSR is the route cache. The route cache strategy is utilized to reduce overheads and peer-to-peer delay, which means in brief, allowing an intermediate node to reply a RREQ message. In this paper, we concentrate on the DSR protocol and the strategies which are proposed to improve its performance. We indicate that some of the strategies are so novel that they can be extracted as an individual protocol with a little complementarity. As a result, we establish a semi-proactive protocol composed of the Active Packets and RERR flooding, both of which are improving strategies on the route cache of DSR. Simulation results show that it can be used as a protocol under a certain circumstance and has a performance outperforms its source strategies and DSR on several metrics.
