Advanced networking technology and increasing information services have led to extensive interconnection between Building Automation Systems (BAS) communication protocols and Internet, which makes Fog computing service a potential solution for automation of building end devices. However, the connection to Internet and public networks increases significantly the risk of the BAS networks being attacked...
Context-awareness is a key ingredient in any ubiquitous and pervasive system and provides intelligence to the system, allowing computing devices to make appropriate and timely decisions on behalf of users. One of the important aspects of mobility management is the dynamic selection of the best access network for a multimodal device when there is a need to perform a handover. Multi Attribute Decision...
Reducing cost of service is an important goal for Service Discovery technologies. The shortcomings of transhipment-method and hibernation-method are to increase holistic cost of service and to slower resource discovery respectively. To overcome these shortcomings, a new method based on context-aware computing is developed. This method, firstly, analyzes the courses of devices using Service Discovery...
DSSR is one of protocols for context-aware services in SANETs. By using user contexts, only the sensors that are relevant to a device's operating pattern transmit messages to the actuator. However there are some drawbacks for SANETs. To address DSSR problems, a routing protocol PAAR is proposed. Simulation studies show that our approach can lead to significant reductions in routing traffic and increases...
