Abstract Motivation

• A home network system (HNS) architecture
  integrated with wireless application protocol
  (WAP) and short message service (SMS) to support
  the connectivity between home and Internet/global
  system for mobile communication (GSM) networks.
• The main object of the integrated system is to
  remotely monitor and control the devices in the
  HNS via laptop computer or a GSM mobile terminal.

System Architecture (1)
4
System Architecture (2)

• An HNS gateway
• Appliances subsystem
• Security subsystem
• Messaging subsystem

5
Communication (1)
6
Communication (2)

• WAP protocol communicate with GSM network
• HTTP protocol communicate with Internet
• SMS protocol communicate with GSM network

7
Notification (1)
8
Notification (2)

• HNS alert message can be sent to remote mobile
  phone via SMS protocol

9
Manager-Agent model
10
HNS management protocol

• Managers can configure, diagnose, and maintain
  home devices which are connected to HNS via the
  HNS management protocol
• The management protocol employs the concept of a
  client-server model, which in turn, forms the
  basis for manager-agent model
• An agent entity resides in each managed device
• The manager resides in the HNS gateway

11
Command format for management services (1)
12
Command format for management services (2)

• The service field specifies HS_GET_DATA or
  HS_SET_DATA
• The objects field is an object identifier
• Data is the value of the object

13
HNS gateway (1)
14
HNS gateway (2)

• The HNS gateway provides the interlinking of the
  controlled home network and the Internet/GSM
  network.
• The HNS gateway performs the protocol
  translations between the controlled home network
  protocol and the HTTP/WAP/SMS protocol.

15
Protocol stack (1)
16
Protocol stack (2)

• The left-hand plane is the HNS termination
  protocol stack consists of three layers
• --- Physical layer (PHY)
• --- HNS protocol stack
• --- Management protocol
• The right-hand plane is SMS, HTTP and WAP
  protocol stack.

17
HNS implementation (1)

• The HNS gateway
• --- A pentium-level desktop PC with Linux
• operating system
• Web server
• WAP gateway
• Remote access service server
• Short message driver
• HNS configuration tool

18
HNS configuration tool (1)
19
HNS configuration tool (2)

• Functions
• --- List
• --- Add
• --- Delete
• --- Refresh
• --- Change
• --- Preference

20
HNS status (1)
21
HNS status (2)

• Data consistency problem
• New appliances in the configuration tool
• ----- HNSs Wireless Makeup Language (WML)
  and
• HTML pages
• ----- Common Gateway Interface (CGI)

22
Implementation of home network subsystem

• Home appliance subsystem
• --- Air-condition
• --- Light system
• Security subsystem
• --- Charge-coupled device cameras connected
  to a PC as an
• surveillance system
• Messaging subsystem
• --- E-mail system (POP3 or IMAP4 protocol)
• --- mail servers address, user IDs,
  passwords, and GSM phone
• numbers must be given to HNS gateway
  in advance

Conclusion

• An HNS architecture consists of three subsystems
  provides remote monitoring and control of home
  appliances that are managed by the home gateway
• The home gateway has the ability to actively
  notify home users in remote locations
• The home gateway can push the altering message to
  home users

27
Future research

• Extend the HNS with real-time processing
  capabilities
• Develop authentication and security mechanisms
  for HNS
• Study distributed component object model (DCOM),
  common object request broker architecture
  (CORBA), or Java remote method invocation (Java
  RMI) for the remote invocation approach of HNS
• Implement more home network service and
  applications
