Poster Abstract: Energy Efficient Mobile Data Collection from Sensor Networks with Range-Dependent Data Rates

Abstract

This work presents a variation of a data collection problem referred as TSP-Data Collection (TSP-DC). Previously we have demonstrated that a two-stage algorithm using Linear-Programming Optimization and Gradient-Descent Optimization (LPO-GDO) is able to solve TSP-DC for minimum tour time. This poster abstract shows that LPO-GDO is also able to solve TSP-DC for an objective function of minimum energy, giving different solutions for different relative energy costs of data transmission and sink movement, and for high or low data loads at sensor nodes.
