A problem related to searching routes of a mobile robot involves finding the route that has the shortest distance and consumes the least energy, or an energy-efficient route. An ant colony optimization (ACO) algorithm can be used to solve this problem, but only on a flat terrain, since energy is depended on the distance. The adapted ACO can also be applied for searching the energy-efficient routes...
Nowadays, an industrial wireless sensor (IWS) is interested and widely used by various industries. There are many industries trying to adopt qualified IWS products in competitive market for gaining advantage. The challenge in choosing IWS includes not only the price, but also several factors, e.g., operating frequency, data rate, output power, interface, brand, and so on. These factors cause difficulty...
A challenge in searching an optimal route of a mobile robot involves finding the route that has the shortest distance and consumes the least energy. To solve this problem, an ant colony optimization (ACO) algorithm can be used, but only on a flat terrain, since the energy depends directly on the distance. In a rough terrain, the least energy route might not be the shortest distance. Also, the shortest...
Recently, heterogeneous wireless networks have been integrated to provide mobile users to access services without restriction of different access networks, e.g., cellular systems and WLANs. Thus, the mobile users can obtain the services with higher data rate and quality in anywhere and at any time seamlessly. To support such scenario, it requires a vertical handover (VHO) mechanism that can decide...
A problem related to energy consumption of a mobile robot involves finding out what route the robot can take that uses the least energy. An ant colony optimization algorithm (ACO) can solve this problem. However, it is applicable only for route on a flat terrain. This paper proposes an adapted ant colony optimization (adapted ACO) algorithm that is applicable for route on a rough terrain as well....
An operation of indoor and outdoor localization mechanisms cannot be fully integrated because the techniques and operation methods are different. As the consequence, a seamless mobility support in location based services for mobile applications cannot be achieved. They still face discontinuity of services when the mobile users move from indoor to outdoor and vice versa, or between WLANs and cellular...
Currently, there are several wireless access networks available to support mobile users. Furthermore, new services have also emerged and aim to allow such mobile users to access the services from anywhere at any time without interruption while moving across heterogeneous wireless access networks. The new services require internetworking and integrated solutions between existing heterogeneous wireless...
Operation of indoor and outdoor localization cannot be combined because the techniques and mechanisms cannot be shared or worked together. Consequently, they are not integrated to support seamless mobility in the application level, e.g., still discontinuity of service when the mobile users move from indoor to outdoor and vice versa. This paper presents the Location Base Protocol (LBP) designed to...
In current HDDs (Hard Disk Drives) production line, the calibration process of burn-in chambers is required an engineer to manually monitor temperatures at the hybrid temperature recorder throughout the period of calibration process. It is a time consuming and inefficient operation, due to a large amount of burn-in chambers used in the production line comparing with a limited number of engineers to...
Recently, the ant algorithm has been widely used to solve the problem of searching for optimization route from various different paths. The ant algorithm can also be applied for searching an appropriate route that consumes less energy in mobile robot area, which is similar problem domain. However, in order to apply, the ant algorithm is required to adapt due to the factor of energy that must be considered...
Currently, the calibration of burn-in chambers used in a HDDs (Hard Disk Drives) production line requires an engineer to manually monitor temperatures at the hybrid temperature recorders throughout the entire period of calibration process. It is a time consuming and inefficient operation, due to a large number of burn-in chambers used in the production line comparing with a limited number of engineers...
Synchronization in a distributed virtual environment (DVE) involves mechanisms to ensure a consistent view of a virtual world for all participants. Most applications in the DVE are related to collaborative activities that include non-contention and contention cases. Using transmission of update messages is suitable enough to support synchronization for only non-contention activity. The contention...
