Abstract
Aiming at problem of congestion and energy consumption caused by funneling effect of multi-hop aggregation wireless sensor networks( WSNs)
propose heterogeneous-bit-rate-based WSNs congestion control technology
by increasing bit-rate of transmitting node in funnel region to improve processing ability. To implement heterogeneous-bit-rate transmission
sensor node composed by ATmega128 microprocessor and CC1100 RF chip is designed
and support multi bit-rate communications; improve component of Tiny OS in software to convert bit-rates dynamically. The experimental results based on real environment shows that network congestion is relieved effectively while fiow gets saturated
