Effective Flooding over Disaster Tolerant Ad Hoc Network based on exchange of Neighbor Information

摘要

Mobile Ad Hoc Networks (MANET) is a useful means instead of network infrastructure when disaster happens. In this situation, information distribution without addresses of nodes is able to be realized by the existing Simple Flooding (SF). But SF causes redundant message transmission, performance degradation and waist of finite battery resources. Making network lifetime without external energy source as long as possible is one of the main goals in case of any disasters or emergency situations. We propose a new broadcasting method that allows reducing power consumption by decreasing a number of redundant rebroadcastings, "Effective Flooding based on Neighbor information Exchange-Revised (EFNEX-R)". Through computer simulation, we showed the effectiveness of our method compared with existing Simple Flooding.
