Project Details


Wireless Sensor Networks (WSN) can be widely used to collect ambient temperature, humidity, gas concentration, presence of intruders. With use of traditional WSN without internet, many applications such as home automation, healthcare or intelligent applications in large open space and public building will be limited as it cannot be connected to cloud directly. However, Internet of Things (IoT) that is embedded with chips and sensors can connect to humans, devices, internet and clouds intelligently to form a ubiquitous network. This network can cover all everyday objects such as watches, keys, household appliances, cars, and buildings in a distributed fashion. In the long run, IoT can become an inherent part of areas such as electricity, transportation, industrial control, retail, utility management, healthcare, water resources management to greatly improve productivity and our lives. Refrigerators, washing machines, vending machines and containers, previously considered as unrelated to communications, can now be networked with intelligent communication modules. As more devices are added into communication networks, ubiquitous networks will take shape and grow. However, different devices used in IoT are heterogeneous in nature as they operate with different standards and use different medium access methods to communicate. Basically, it integrates multiple wired and wireless communication, control, and IT technologies, which connect various terminals or subsystems under a unified management platform that employs open and standardized technologies. Hence, it is essential to design standard protocols, coexistence mechanisms and synchronization methods so that all heterogeneous devices can function globally. Besides, performance analysis in terms of latency, throughput and energy consumption due to standard protocols needs to be analyzed to improve their efficiency further. In the Two years of this project, standard protocols will be developed to maintain synchronization among various heterogeneous devices used in IoT and models will be designed to analyze performance of different devices. In the First year of the project, coexistence mechanism among various heterogeneous devices will be analyzed and new synchronization methods will be proposed. Besides, standardization protocols will be developed that can work globally for the IoT devices. In the Second year of the project, analytical models of medium access control mechanism in terms of latency, throughput and energy consumption between IoT gateway and other heterogeneous devices of 6LoWPAN, WSN, Bluetooth, and Wi-Fi will be designed. A real world shopping mall IoT application will be implemented and simulation, model validation, and performance evaluation of our proposed models will be done in both years of the project.
