Please help with A, B and C. Full and good answer will be upvoted.

We are living in a peaceful world with good healthcare and abundant food. People are living longer and longer. It is the society's responsibility to ensure old people a good quality of life. A new technology, i.e. the wireless sensor network (and nowadays called Internet of Things when they are connected to the Internet), can be deployed in a senior house to assist the living of elderly people. In a wireless sensor network, sensor nodes are equipped with different sensors (e.g. temperature, humidity, vibration sensor) for data connection. Sensors can be put under the bed to monitor the sleeping pattern of a patient. Fall detection sensors can also be mounted to detect emergency situations, such as the falling of a patient. Service personnel will be able to provide better service with the information provided by the sensor network. a) Are there security threats when a sensor network is deployed to monitor the living status of elderly? What kind of threats are they? (2p) More information: a sensor node is usually a battery-powered embedded device with one or multiple sensing functions (e.g. pressure, temperature, etc.) and a wireless transceiver. b) Suggest your solution to secure the using of a sensor network (or Internet of things) in a senior house. (2p) c) What are the social and ethical concerns here to deploy a sensor network in a senior house? Suggest how we can involve the participation of customers and their families in the early stage of the system design and during the using of the smart system to gain their trust to the service provider.
