We propose a system, called Triage, that automatically performs onsite software failure diagnosis at the very moment of failure. Expand

A multifrequency MAC specially designed for wireless sensor network applications

G. Zhou, Yafeng Wu, +4 authors T. Abdelzaher
Computer Science
TECS
1 March 2010

We propose MMSN, which takes advantage of multifrequency availability while, at the same time, takes into consideration the restrictions of wireless sensor networks. Expand

Range-free localization and its impact on large scale sensor networks

T. He, Chengdu Huang, B. Blum, J. Stankovic, T. Abdelzaher
Computer Science
TECS
1 November 2005

We present APIT, a novel localization algorithm that is range-free that performs best when an irregular radio pattern and random node placement are considered, and low communication overhead is desired. Expand
