Abstract:Wireless Sensor Networks (WSNs) is a promising
technology that can be employed torealize manyversatile
applications fordaily life. Sincethe existing congestion control
mechanisms used in wired/wireless networks are not tailored to
WSNs, a Topology-Aware Resource Adaptation (TARA)
approach was proposed tocope with the congestion issue in
WSNs. However, the TARA approach does not address the sink
hotspot issue.This paper proposed an Adaptive Base-Stations
Placement (ABP) approach. The ABP approach can
designateseveralsensors with high residual energy as the base
stations and can adaptively activate the base stations to relay
packets to the sink by making use of a robust scheduling
scheme, so that the congestion near sink nodes can be alleviated
and the lifetime of the WSN can be improved. To validate the
ABP approach, we conduct simulation study. The simulation
results show that the ABP approach can evenly schedule the
packet transmission to reduce traffic load and can improve the
lifetime of the WSN about 16 percent.
