ToR 2 Review and Identify

• ToR 2.1 Characteristics, Commonalities, and
  Differences
• Unique sensor network characteristics are
  captured (TD Section 5.1).
• End-user service models depend on end users and
  change dynamically according to user
  requirements.
• Different sensor network applications inter-work
  each other, forming a multi-domain communication
  relationship.
• End users of sensor network applications and
  services could be arbitrary users as well as
  dedicated users.
• Wired/wireless sensor networks are the extension
  of Internet towards the physical environment.
• Main objective of a sensor network implementation
  is to gather and pre-process sensor data.
• For many wired/wireless sensor network
  applications, sensor data has to be associated
  with sensors location data.
• In most cases, the nodes have to work
  collaboratively in order to solve complex sensing
  problems.
• The nodes have to communicate with each other
  without an existing communication infrastructure.
• Computing has to be resource-aware due to the
  limited resources within the wireless sensor
  network.
• Topology has to adapt to availability of
  communication, to changing positions, energy
  levels and roles of nodes.
• Wireless sensor network has to work for a long
  time without maintenance.
• Sensor networks are application-oriented/focused
  networks ultimately for human users.
• Above unique characteristics are derived from the
  commonalities and differences identified from the
  applications studied (TD Section 4) thus the
  commonalities and differences are implicitly
  included in the unique characteristics.
• Details of the commonalities and differences will
  additionally identified when the sensor networks
  system/reference architecture study is completed
  in 2009.

• The SNRA, which describes generic
  applications/services, is the representation of

  sensor nodes and gateway systems in terms of
  operation layer and functional and interoperation
  interfaces.
• High-level operational SNRA graphics, node
  connectivity diagrams, system description and
  architecture, services functionality in terms
  of network layers, operational layer view for
  functional elements (applications and services),
  service access points, and interfaces and
  relevant data types are developed and described.

• For 2009, SGSN requests that JTC 1 SCs and SDOs
  to appoint a representative or a liaison officer
  to SGSN in order to have a better communication
  and information exchange.
• In 2008, SGSN used bulk e-mail to solicit and
  request for information however, this method has
  turned out to be ineffective.
• With a dedicated/appointed individual from the
  organizations, the communication between SGSN and
  SCs/SDOs is expected to improve.

  different options for SN standardization
  coordination within JTC 1. They are
• Let the existing SCs handle the existing work
  items as per their scope

• Foundation for a new SC
• Transform SGSN to a SN Special Working Group
  under JTC 1 to coordinate the SN standardization
  activities with JTC 1 SCs, SDOs, consortia, fora
  and industry, and also to handle standardization
  of SN need areas that no SC has the work scope.
