The number of children dying because of heatstroke after being left in the car is worrying. From 1998, there are about 618 children have died in the United State of America (USA) because of heatstroke. It was the leading cause of fatalities in non-crash incident in USA. The same situation also arises in other countries. Life stress is being identified as among the factor that lead to this incident. In this paper, we proposed the used of Android Apps with an Estimote Beacon, a bluetooth device, to warn parents or guardians about their children being left in the car. An alarm will be raised after the parent leaves their children at prespecified range to avoid any risk of heatstroke from occurring.

Abstract. Radio Frequency Identification (RFID) technology is among the key technology of Internet of Things (IOT).It is a sensor device that can monitor, identify, locate and tracking physical objects via its tag. The energy in RFID is commonly being used unwisely because they do repeated readings on the same tag as long it resides in the reader vicinity. Repeated readings are unnecessary because it only generate duplicate data that does not contain new information. The reading process need to be schedule accordingly to minimize the chances of repeated readings to save the energy. This will reduce operational cost and can prolong the tag's battery lifetime that cannot be replaced. In this paper, we propose an approach to minimize energy spent during reading processes. Experiments conducted shows that proposed algorithm contribute towards significant energy savings in RFID compared to other approaches. [5]. It enables process improvement on the area where it turns tedious manual works into simplified automated process. For example, instead of scanning the barcodes manually, RFID can simultaneously read all the objects and return related data to the system in very short time [6]. The growth of RFID deployment has been exponential since its reintroduction in the late 90s. In 2006 the number of tags has been sold is three times bigger than over the previous 60 years [7]. In 2014, the total market value for RFID is $9.2 billion and is expected to reach $30.24 billion in 2024 [8]. IntroductionBased on this market pattern and trajectory, it is expected that RFID will becoming the most common pervasive devices in our life. As the most widely used technology, we need an energysavings mechanism to cut the system operational cost. Minimizing the usage also can prolong the devices lifetime which help businesses obtain longer return-on-investment period. In certain circumstances, such as deployment at a natural disaster place [9], energy savings conscience is very important as the energy resource were limited and hard to be renew. For example the use of active tag to detect trapped coal miners in the tunnel [10]. The evacuation need to be done quickly before the battery on the tag dried out.In this paper we present how energy savings is achieved through efficient reader scheduling mechanism. The readers are schedule in a way that no adjacent reader will do reading at the same time. Based on this the risk of signal collision is reduce to zero and the need to repeat readings because of the collision can be avoided. The tag in the overlapped vicinity also can be read by only one reader

The motivation of this paper is to review some of the leading research issues encountered by current Complex Event Processing (CEP) techniques. General CEP system undoubtedly laid a certain degree of uncertainties due to some unforeseen reasons such as inaccurate measurements through network failures or unpredicted interference from the system failures. A variety of traditional to the most current techniques was disclosed with some features, which are rarely considered in typical CEP problems. Besides, this paper also discusses a broad review of modern and future solutions, including techniques beyond mainstreams in complex event processing. Based on the critical analysis of prior techniques and solutions, therefore, we further the research and propose a solution for a new type of event processing engine especially in RFID for future reference.
