Performance Comparison of Routing Protocols for Vital Data Monitoring from a Large Number of Exercisers

摘要

In this work, we focus on vital data monitoring of people playing various types of sports. We assume a system configuration in which sensor nodes attached to exercisers with their back-waist positions sense vital data and send them to a sink node. The communication range of each sensor node is limited in this environment, therefore, the sensed data needs to be delivered to the sink node through multi-hop transmissions. In this paper, we present simulation results of RPL (IPv6 Routing Protocol for Low power and Lossy Networks) that is a widely-used routing protocol in wireless sensor networks. We evaluate data collection rate of RPL, and compare its performance with that of conventional flooding when these schemes are applied to vital data monitoring of people playing various types of exercises. With obtained numerical results, we discuss challenges in multi-hop transmissions for vital data monitoring of a large number of exercisers.
