Abstract:
Instead of using static nodes in wireless sensor
network, implementation of hardware and mobile
environment are challenges of mobile wireless sensor
network. Mobile sensor nodes combined with wireless
network is one of research area and mobility is one of key
factors in designing mobile wireless sensor network. To
analyze vehicle mobility, this work implements a mobile
sensor node in WiFi network and it is equipped with
ultrasonic sensor and ESP8266 NodeMCU. The sensor data
can be monitored on ThingSpeak over the internet via
wireless LAN and its measurement can be taken within 10 s
delay. MikroTik (RB931-2nD) router is used as an access
point in system architecture. Experiments are performed to
study mobility effects on network throughput when mobile
sensor node is moving with constant velocity of 10 cm/s. With
connectivity in wireless LAN 802.11/n technology, signal
strength and throughput are measured for vehicle mobility.
