2 Emergency Communications What we use when many things are not working well! (Fred Baker, Cisco) 100% Zero infrastructure => something that works 2

3 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 3

4 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 4

20 DUMBO II MANET + Infrastructure

21 DUMBO ll: : A V-2-I V I Emergency Network 2008 ITST Conference, Phuket 21

22

23 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) 23

24 1. V2V Scenario -- mixed types of vehicles 24

25 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) 25

26 DUMBO II Experiments 1. OLSR + Internet 2. MANEMO (MANET + NEMO) with mobile routers communicating with 1. TD/NINA Protocol 2. OLSR Protocol 26

27 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 27

28 OLSR DUMBO II topology OLSR network Tuk tuk boats OLSR gateway 12 nodes 6 EEE PCs 5 Ultraclients 1 OLSR GW 28

29 2. V2I Scenario -- with access points + group movements Sea Vehicles Fixed Terrestrial Infrastructure Land Vehicles 29

30 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 NEMO Platform for Linux (NEPL) 30

31 NEMO Visited Network Access Router A Internet Home Network Access Router B Mobile Router Mobile Network Nodes 31

32 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:

33 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 33

34 MANEMO(cont.d) We can deploy Headquarter 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 34

37 Physical topology The blue line represents the communication path between boat and HQ 37

38 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-andforward, RSS feeds Intelligent information processing 38

39 Deployment Issues Locating optimal positions to setup wifi devices Re-configuration MANEMO is more complex as compared to OLSR Sea Sickness Battery Lifetime 39

40 Work in Progress Auto re-configuration Parameter settings Active Networks Mapping and location information Google Map GeoDraw 40

46 46

47 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. 47

48 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 48

49 Trainings for Myanmar Engineers at interlab/ait May

50 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 50

51 Yangon - Pyapon: 75 Km (Point-to- Point) satellite link (IPStar) 51

52 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!!!) 52

53 Latest DUMBO Deployment report Site: Myingagone village Pyapon Township 12 EeePCs w/ DUMBO OLSR, 50 metre between each node. 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. 53
