"On the K-Weak Coverage of Random Mobile Sensors" by Sajal K. Das and Rafal Kapelko
 

Abstract

This paper studies the fundamental problem of energy consumption in the movement of mobile random sensors ensuring k-weak coverage on the domain. In particular, we analyze two notions of k-weak coverage on the unit square, namely (1) (k, x)-weak coverage in which every straight-line path across the width of the unit square passes through the sensing range of at least k sensors; and (2) (k, x, y)-weak coverage in which every straight-line path across the width and the length of the unit square passes through the sensing range of at least k sensors. The number of reliable and p-reliable sensors (i.e., each sensor is reliable with probability p independently from other sensors) in energy-efficient reallocation is optimized to provide the desired k-weak coverage. For reliable sensors, we discover sharp decrease in the expected minimal energy consumption in the movement to provide the desired k-weak coverage as a function of the number of sensors. For p-reliable sensors, we design and analyze two energy-efficient algorithms to ensure the k-weak coverage. The novelty of the paper is in the theoretical understanding and analysis.
