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
