Abstract

The effect of topology changing caused by nodes mobility on too much overhead occupying the limited bandwidth and resource has been greatly alleviated by a routing timer self-adaptive regulating (RTSAR) algorithm based on MIMD loop control proposed for mobile ad hoc network in this paper. Served as a stable HELLO message broadcasting algorithm, RTSAR has been designed on a fairly converging mathematical model which is established to obtain a relative stable transmission pattern. By controlling the value of routing timer, RTSAR as an independent algorithm module will help the protocol be able to send more HELLO messages in a high dynamic network to avoid frequent routing discovery processes and less in a relative stable environment to save the unnecessary control packets. Results of simulations on NS2 showed that adopting RTSAR, no matter based on a table-driven protocol or on a demand one, would reduce the overhead in networks effectively while hardly bring any obvious impacts on metrics of packet successful delivery rate and the average end-to-end delay as well.
