Abstract:
Data aggregation is a key energy saving functionality in wireless
sensor networks (WSNs) for both data gathering applications and
event-based applications, since the communication cost is often the
higher order of the computation cost. Through data aggregation, we
can reduce the scale of data while maintaining the correctness of
data for a set of symmetric functions called divisible perfectly
compressible (DPC) functions. Also the achievable minimum data rate
among all sensor nodes is limited for random WSNs if we insist data
from ALL sensors should be collected. Hence we use gathering
efficiency to indicate the number of nodes whose data are gathered.
It is intuitive that there exists a tradeoff between the aggregation
throughput and gathering efficiency. This document introduces
adaptive data aggregation schemes for WSN to consider the tradeoffs
between the aggregation throughput and gathering efficiency.
Specifically, the adaptive data aggregation schemes includes two
protocols, Single-Hop-Length (SHL) Scheme and Multiple-Hop-Length
(MHL) Scheme, for different gathering efficiency requirements.
