RAMP Status Report

RAMP Status Report

RAMP Overview

• Receiver-initiated, mesh-based multicast routing
  protocol for wireless ad hoc networks
• A core is elected per connected component to
  announce its address as the location of a
  multicast group
• Core announcement diffused periodically in the ad
  hoc network
• Receivers requiring to join the group transmit
  join announcements to their next hops towards the
  core based on the information they obtain in core
  annoucements

RAMP Overview

• Nodes overhearing join announcements from
  multiple neighbors join the group silently.
• Loop-free packet forwarding obtained by
  intelligent flooding of multicast data packets
  within the mesh by members and silent members

RAMP Features

• Does not need an underlying unicast routing
  protocol
• Does not need per source flooding of control
  packets
• RAMP more effective than ODMRP and MAODV for a
  wide range of scenarios of varying mobility,
  group members, number of senders, and traffic
  load based on simulations in Qualnet 3.1

RAMP progress till now

• A paper titled Receiver Assisted Mesh Protocol
  (RAMP) submitted to Mobicom 2003. Paper
  available online at http//www.cse.ucsc.edu/ra
  vindra/ramp_mobicom.pdf
• Code developed and tested for a Linux
  implementation of RAMP. Complete source code and
  instructions for building and using the code
  available at http//www.cse.ucsc.edu/ravindra/r
  amp_linux.html

RAMP work in progress

• Generation of a detailed code description
  document of the Linux code for RAMP. Expected
  date of completion 5/23/2003
• Integrating the Linux code of RAMP with mrouted,
  and supporting multiple interfaces. Expected date
  of completion 5/29/2003
