Abstract
Recently IoT(Internet of Things) is the most popular topic in the world. It shows that everything can be a sensor node, and send the data from wireless network. Many issues related to this topic need to be solved such as the power consumption problem and how to collect the data. The Bluetooth 4.0 Low Energy let the device activity time from hours to days. The problem with data collection is that sensor nodes may not have Internet connecting ability or in the connection range of node which has Internet connecting ability(sink node). Those nodes may need some other node to relay the data to the sink node. So we should use the routing method to find a suitable path. In this research we focus on the transportation like bicycle which is placed in the parking space and use Bluetooth Low Energy as the communications protocol. Our algorithm design is based on two main purpose, one is to use the short length broadcast packet to construct route and reduce the network congestion. Another is that bicycle may leave or enter randomly, so we should have lower response time when bicycle leaved in the dynamic environment. In this thesis we will study on the network topology construct strategy and transmission route algorithm. We also use simulations to prove that we have the better transmission efficiency.
