RIPPLE: AN EFFICIENT TEAM MULTICAST PROTOCOL IN WIRELESS AD HOC NETWORKS USING DIRECTIONAL ANTENNAS
In this paper, we study a novel team multicast routing protocol called “ripple, which is an improvement of Multicast-enabled Landmark Ad Hoc Routing (MLANMAR), for mobile ad hoc networks using directional antennas. It is designed specially for the scenarios using directional antennas with team mobility to satisfy the need to propagate messages to all the members within a group. One of the limitations of M-LANMAR lies in its employing flooding to deliver messages in a group. Concerned with the directional antennas which offer tremendous potential for improving the performance of ad hoc networks, flooding will bring about considerable increase of the number of transmission and extra messages transmitted, which will cause a notable decline in the energy level nodes hold and the function of the whole network. For the reasons above, we propose a mechanism with diffusing the messages circle by circle to finally cover the whole members of the group. The main contributions of this paper are listed as below: proposing a new team multicast protocol, named “ripple, for ad hoc networking with directional antennas; extending the message structure of M-LANMAR protocol; describing the operation of our protocol in detail; evaluating the performance of both protocols by theoretical model deduction and simulative implementation respectively.
