Enhancements of ODMRP for Improving Packet Reachability in Ad Hoc Networks
Takahiko Kibe, Toyofumi Takenaka (Nihon Univ) NS2007-184
Abstract (in Japanese) (See Japanese page) 
(in English) An Ad Hoc network is a set of wireless terminals and almost of them have the characteristics of mobility and portability．Therefore，even if the communication paths are constructed between wireless terminals，the communications happen to become impossible by terminal moving．In order to improve the data transmission quality in a Ad Hoc network, we propose some enhancements of On-Demand Multicast Routing Protocol (ODMRP) that is originally designed as a multicast protocol for Ad Hoc networks. The ODMRP creates Forwarding Group (FG) nodes for data transmission, which is executed by means of broadcasting only by the FG nodes. Due to this broadcasting mechanism, the ODMPR can maintain higher quality of data transmission than the AODV when the order of FG nodes changes. However, since the FG nodes are selected only on the shortest path between the source node and destination node, the date transmission can be broken by FG node moving. In order to cope with this problem, we propose some enhancements of ODMRP, where the nodes, which are located within some range of FG nodes, are added to FG. We executed simulation experiments to evaluate the data transmission quality of AODV, ODMRP and our proposed methods and show the effectiveness of the proposed methods.
