Abstract:
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. Keywords:WSNs, Congestion Control, Base Station
