Automobile driver information as displayed on marked road signs indicates the state of road, traffic conditions, proximity to schools, etc. These are important insure safety and pedestrians. They also input automated advanced assistance system (ADAS), installed in many automobiles. Over time, arrow-road markings may be eroded or otherwise damaged by automobile contact, making it difficult for correctly identify marking. Failure properly an marker creates a dangerous situation that result...

This paper proposes a new protocol that can be used to reduce transmission delay and energy consumption effectively. will done by adjusting the duty-cycle (DC) ratio of receiver node contention window size sender according traffic congestion for various devices in Internet Things (IoT). In conventional MAC protocol, data latency unnecessary are caused high collision rate. is because cannot sufficiently process transmitting during peak time when reception have same ratio. To solve this...

Environment maps must first be generated to drive mobile robots automatically. Path planning is performed based on the information given in an environment map. Various types of sensors, such as ultrasonic and laser are used by acquire data its surrounding environment. Among these, sensor, which has property being able go straight high accuracy, most often. However, beams from sensors refracted reflected when it meets a transparent obstacle, thus generating noise. Therefore, this paper,...
