Emergency Communications

What we use when many things are not working well!

(Fred Baker, Cisco)

100% Zero infrastructure

=> something that works

Issues to be addressed

• Temporary services– Service outages and subject to attacks– Limited resources

• Equipment• Power supplies• Manpower

– Need for preferential traffic/services for authorized users

More..

• Work under stress!– Poor working conditions– Life saver– Rapid dissemination of announcements– Support bi-party and/or group communications

• Services– Expert consultations– I AM ALIVE (eg. WIDE Project) – Missing persons

Outline

• Lessons from 2004 Tsunami • Design principles• DUMBO Project

– 2006 DUMBO I– 2008 DUMBO II– 2010 DUMBO III

Digital Ubiquitous Mobile Broadband OLSR

(DUMBO)

Multimedia Communications for Disaster Emergency Responses

• Interactive Video, Voice, and Instant Messaging – very important to situational awareness

• Peer-to-Peer Paradigm ( no centralized server ** )

Application

Face Recognition : to search and identify people

DUMBO II

MANET + Infrastructure

DUMBO ll: A V-2-I Emergency NetworkDUMBO ll: A V-2-I Emergency Network20082008

ITST Conference, PhuketITST Conference, Phuket

Objectives

1 Vehicle-to-Vehicle (V2V) communications

with mixed vehicle types

2 Vehicle-to-Infrastructure (V2I) Internet-like

Gateway

3 A newly revised Emergency Response

Multimedia Communication Applications

(P2PSIP)

1. V2V Scenario -- mixed types of vehicles

Equipment List

• Power Station2 (Wifi Access Point)

• Microclient Jr. (Mobile Router)

• Ultraclient (OLSR Router)

• Laptop PC (MNN)

• EeePC (MNN)

• Desktop PC (HA, Tunnel Server, CN)

DUMBO II Experiments

1. OLSR + Internet

2. MANEMO (MANET + NEMO) with mobile routers communicating with

1. TD/NINA Protocol

2. OLSR Protocol

OLSR in DUMBO II• We deployed post disaster communication network • OLSR network connected to the infrastructure

– Using a OLSR gateway with 2 interfaces, ad hoc wireless mode connecting to OLSR network and LAN connecting to HQ.

• EasyDC was the P2P application on MANET supporting VoIP, VDO, and Instant messaging, using our P2P SIP overlay network – Rescuers could make any kinds of communication to other

rescuers or HQ– It was distributed, thus there was no need to setup any

centralized SIP server• P2P SIP provide session and terminal mobility

Network Mobility (NEMO)• When a whole IP subnet moves, how does it

retain connectivity with different infrastructures ? – Addressing, Home network, Visited network,

Mobile router, Access Router

MANEMO

• Each of MANET and NEMO alone may not answer to our Post-Disaster Communication Network requirements !!

• MANEMO = MANET + NEMO

• It is an emerging research area: – http://www3.ietf.org/proceedings/07mar/slides/manet-11.pdf

– http://www.mobileip.jp/MANEMO/MANEMO.html

MANEMO

• MANEMO = Mobile Ad hoc Network (MANET) for Network Mobility (NEMO)

• NEMO provides session connectivity

• NEMO Mobile Router (MR) acts as a MANET node and exchange information with other MRs (TD/NINA vs OLSR)

• MANET provides optimal exchange of information between local networks

• Nested NEMO extends the network coverage

MANEMO(cont.d)

• We can deploy Head-quarter freely in the Internet

• Each Vehicle for rescue work usually equipped with MR

• Rescue terminal requirement is only IP (same as NEMO)

• By using MANEMO, the problem of NEMO such as multiple encapsulation in nested case, redundant path inside nested MRs, and the isolated network without Home Agent can be solved

3. Emergency Applications• Dealing with session and

terminal mobility• Cross-layered approach

(utilizing useful information from the routing layer) with OLSR

• Information delivery: streaming, store-and- forward, RSS feeds

• Intelligent information processing

Deployment Issues

• Locating optimal positions to setup wifi devices

• Re-configuration

• MANEMO is more complex as compared to OLSR

• Sea Sickness

• Battery Lifetime

Work in Progress

• Auto re-configuration– Parameter settings– Active Networks

• Mapping and location information – Google Map– GeoDraw

DUMBO-MM

Cyclone Nargis on May 2, 2008

Ayeyarwaddy, Myanmar

www.interlab.ait.ac.th/myanmar/cyclone/

2 May 2008 – Nargis cyclone hit Myanmar.

– Devastated Five Divisions and States including Yangon.

– Delta areas, the worst-hit, with the heaviest casualties and infrastructural damages.

– Communication infrastructure was down in cyclone hit areas.

– Electricity Black-out.

– Very limited transportation.

• DUMBO-Myanmar – Useful in handling of relief, recovery and

resettlement activities aftermath of Nargis Cyclone.

• Coordination Program

– Phase I: Introductory Phase of DUMBO • Part I: Training for Myanmar Engineers at

AIT • Part II: DUMBO Deployment

– Phase II: Utilization of DUMBO systems by government agencies and iNGOs

Trainings for Myanmar Engineers at intERLab/AIT

21 – 25 May 2008

Introducing DUMBO in Myanmar

26 May 2008: Myanmar Egress HQ, Yangon

• Presentation/report to Myanmar Egress/NAG

partners, Myanmar Computer Professional

Association (MCPA)

– Technical overview

– Network requirements

– Benefit/features of system

– Project plan (DRAFT)

27 May- 2 June 2008: Myanmar Engineer’s

site visits to Pyapon and Bogale

Townships

Yangon - Pyapon: 75 Km (Point-to-Point) satellite link (IPStar)

Online among ME HQ, field offices in Yangon &

Pyapon

• ME used DUMBO network for data sharing and day-to-

day communications between HQ and fields office

• even during ME’s logistic arrangement for TCG-PONJA,

data collection for UNICEF and Myanmar Fisheries

Federation (MFF)

• ME is trying to test ‘HQ’- ‘field office’ – ‘field site’

• HQ-field office via iPstar

• Field office-field site (village) via long range wireless

antenna (need special permission, waiting for that !!!)

Latest DUMBO Deployment report

• Site: Myingagone village Pyapon Township

• 12 EeePCs w/ DUMBO OLSR, 50 metre between each

• Utilized DUMBO network during live data collection

• Very useful as Team leader can command and control his

volunteer team and get instant data at mobile office.

• Restrictions: EeePC’s low battery life especially in Mesh

wireless network.
