Implementing a Narrow Waist Abstraction for Sensornets

1
Implementing a Narrow Waist Abstraction for
Sensornets

• Project Update
• Arsalan Tavakoli
• Jay Taneja
• Fall Semester 2005

2
Motivation

• Sensor Network Architecture
• Framework necessary to encourage incremental
  research
• Many pieces are as yet undefined
• Sensornet Protocol (SP)
• First step towards architecture
• Current code lacks a number of features and is
  unsupported

3
Key Ideas of Solution

• Extensibility of Neighbor Table - How can
  multiple network protocols share information for
  efficiency?
• Mechanism/Policy Debate - What decisions does SP
  have to make?
• Transparency of Address Information - Should
  network protocols see link-layer addresses?

4
Current Status and Future Plans

• SP Code is nearly finished
• Testing will be augmented by adding situations
  with multiple network protocols working
  concurrently
• Interfaces to allow link-independent time
  synchronization will be added
