Using
Buddies to Live Longer in a Boring World
Abstract
In a sensor
network monitoring natural environment, the readings of sensor nodes show
high temporal and spatial correlation. This stems from the fact that most
characteristics of natural environment (chemical concentration, temperature,
humidity, pollution, etc) do not change abruptly in space and time. From a
sensor's perspective then, the environmental phenomena are quite
predictable, and hence, "boring". In this paper, we introduce the
novel idea of buddies to exploit temporal correlation. We propose a simple
Buddy protocol to implement this idea. We analyze the performance of the
protocol and identify factors that influence it. We discuss research
challenges that would pave the way for more efficient protocols based on
this idea.

A
simple and elegant idea that extends on our work on PREdiction-based
MONitoring (PREMON) to cut down on idle listening. Two nodes can save each other's battery by taking
turns in answering queries on behalf of each other. With this, only one node
needs to keep its radio ON at any point in time.
