In Problem below, can you comment on the possible use of
(a) Ad hoc network.
(b) Sensor network.
(c) Bluetooth devices.
(d) ZigBee
(e) HomeRF
(f) 802.11 enabled devices
(g) WiMax
(h) WMN
Can you think of ten important parameters that ought to be sensed in a futuristic
automobile? What type of sensors do you need to monitor them constantly?
(a) There is a possible use of ad hoc networks, especially when vehicle in a
group, and confined to a region. Ad hoc can be used as personal area network.
(b) There would be a possible use of sensor networks in the above application as various kinds of sensors will operate and form a network. The user would send queries to the network and then take the appropriate action. For example, if there is a grocery cart just behind the automobile, the driver would remove the cart .rst in order to avoid colliding with it.
(c) There is an immense scope of Bluetooth devices. For example, on
approaching an amusement park, the map would be displayed in the car in
addition to the daily visitor schedule. Or a speakerphone could be installed in
the car. This could be used to receive messages. The driver could also be
reminded of his daily schedule when he/she gets into the car in the morning.
(d) Zigbee network could do similar application as sensor networks.
(e) We could have voice and data transfer between the various devices in the
car. For example, if there is internet access in the car, then one can download
data from the net onto one’s palm pilot. Moreover,we can use HomeRF
technology that will wirelessly link a computer with home and car stereos,
allowing all three to share music .les. Therefore, the driver can choose the
programs he/she wants to hear in advance. The user can also be warned about
impending bad weather if the car is connected to the home wireless network.
(f) This can be used to create network between vehicles, or between devices
installed in the vehicles.
(g) The IEEE 802.16e WiMAX (Worldwide Interoperability for Microwave
Access) mobile technology provides high capacity wireless broadband coverage and services of up to 30 miles from a central tower. Automobiles have large space and battery power to support both cellphone networks and WLAN
networks like WiMAX in the same vehicle. WiMAX will provide enriched multimedia experience to mobile users like allowing users to IM or check stock
quotes while riding in a car. Any WiMAX enabled device employs the IEEE
802.16 upper-layer MAC, scheduler, drivers, protocol stacks, and user application software. By employing WiMAX, high speed transactions with
increased QoS and efficiency is possible occur in futuristic automobiles lie a
high performance bus.
(h) Wireless Mesh network can be used to create network between automobile,
similar to 802.11.

Answer the following statement(s) true (T) or false (F)
1. A bimodal inverter is an inverter type that can operate as either a grid-tie or stand-alone inverter. 2. A converter is a device that converts direct current (DC) electricity into alternating current (AC) electricity. 3. Stand-alone inverters are connected to the batteries in a stand-alone PV system. 4. A true sine wave inverter is suitable for sensitive electronic equipment because it produces an output with very little distortion. 5. Inverter efficiency has improved over the years and now many grid-tie inverters are rated up to 95% efficient.
