| Abstract(in English) | In this paper we propose a transmission range reduction scheme for a clustered wireless sensor network (WSN), in order to reduce power consumption while maintaining the network connectivity, particularly in scenarios where consecutive reporting of sensing values is inherent in the network. The platform WSN is based on a multi-hop clustered algorithm, where clusterheads send information to the sink via either gateway nodes or other clusterheads of intermediate clusters towards the sink. The proposed scheme dynamically reduces the transmission range of sensor nodes in order to save power of nodes whilst ensuring a minimum desired network connectivity is achieved. The main idea of this scheme is that the sink initially gathers the number of nodes in the network and instructs the reduction in the transmission range of the sensors until this number is compromised. Simulation results show the effectiveness of the approach in two different clustering schemes, in regards to reducing energy consumption in the network, where it is possible to achieve a reduction in total network energy consumption by as much as 50% or higher. |
