| Descripción |
In wireless ad hoc networks and sensor networks,
energy use is in many cases the most important
constraint since it corresponds directly to operational
lifetime. This paper presents two topology
control protocols that extend the lifetime of dense
ad hoc networks while preserving connectivity, the
ability for nodes to reach each other. Our protocols
conserve energy by identifying redundant nodes
and turning their radios off. Geographic Adaptive
Fidelity (GAF) identifies redundant nodes by their
physical location and a conservative estimate of
radio range. Cluster-based Energy Conservation
(CEC) directly observes radio connectivity to
determine redundancy and so can be more aggressive
at identifying duplication and more robust to
radio fading. We evaluate these protocols through

analysis, extensive simulations, and experimental
results in two wireless testbeds, showing that the
protocols are robust to variance in node mobility,
radio propagation, node deployment density, and
other factors.
