This paper addresses the joint selection and power assignment of a largest set of given links which can communicate successfully at the same time under the physical interference model in the duplex (i.e. bidirectional) mode. For the special setting in which all nodes have unlimited maximum transmission power, Halldorsson and Mitra [5] developed an approximation algorithm with a huge constant approximation...
The purpose of this paper is to represent a wind powered wireless sensor network system and introduce a novel transmission power control scheme based on remaining energy level and energy harvesting status to extend the lifetime of WSNs. Energy constraint has always been one of the most significant problems of wireless sensor networks along with the development. Many methods have been introduced to...
We consider the problem of adjusting transmission power in wireless sensor networks to create a desired topology. Efficient power control algorithm can greatly reduce the energy consumption as well as to ensure sufficient network connectivity. In this paper, we propose a novel distributed power control algorithm based on PID control which dynamically adjusts transmission power level for each node...
