Design and Analysis of One-Time-Use Sensor Node Leaping Mechanism

Abstract

This paper presents the design and analysis of a new energy-saving mobility mechanism for sensor nodes. Specifically, we propose the one-time-use leaping mechanism that utilizes the ground reaction force generated when releasing multiple precompressed springs mounted underneath individual sensor nodes. Toward enhancing coverage and connectivity in senor networks, our focus is placed on how to control the leaping distance and direction. For the purpose, both the number and pattern of release are mathematically analyzed. Through extensive simulations, we validate the effectiveness of the proposed leaping mechanism for the enhancement of network connectivity, with no additional power consumption.
