A piconet is the type of connection that is formed between two or more Bluetooth-enabled devices, one device takes the role of ‘master’, and all other devices assume a ‘slave’ role for synchronization reasons. Due to the acknowledgement mechanism it may happen that frames are duplicated. What are the Key characteristics of pervasive computing? It has two modes. What are the various issues related to device management in pervasive computing?
Registration of a mobile node via the FA or pervaslve with the HA.
Pervasove a wireless network, the non receipt of ACK may be due to other reasons. The various components of WAP are:. Discuss about its classes. What are the four possible handover scenarios in GSM? Classical transactional services typically benefit from user acknowledgement, for most push service user acknowledgement are not necessary, still WTP acknowledgements can improve reliability.
It ensures the uniformity of data types. What are the additional messages needed by comphting optimized mobile IP?
Jochen Burkhardt, Pervasive Computing: How does registration on layer 3 of a mobile node work? How is synchronization carried out in a Pervasive Environment? Explain the following with respect to mobile IP. The cyclic redundancy check is an error detecting code in which the code is the remainder resulting from dividing the bits to be checked by a predetermined binary number.
What are the functions of MAC management? The products are connected to the internet and the data generate is easily available. Data is transmitted in small portions, called burst.
Delay spread will result in Inter Symbol Interference which can be compensated by equalizers. Write a note on Piconet. Explain the different types of encapsulation techniques in mobile IP.
Problems of a file system in mobile environment: The purpose of the elimination phase is to eliminate as many contending nodes as possible. It is wireless internet. You could buy a wireless router, and be able to have internet in most of your house. The integrating of devices are device- to-device or device-to-server protocol. The user is able to continue operation at exactly the point where the device was switched off. A Tunnel establishes a virtual pipe for data packets between a tunnel entry and a tunnel endpoint.
It was designed to improve on Say something about the push architecture of WAP. State the three phases of the medium access of different competing nodes. Describe Transaction and Session protocols of wireless. Discuss in detail about any two Pervasive Applications of your choice in detail.
What is Minimal encapsulation? Typical wireless networks, the station has to move from one access point to another to provide uninterrupted service.
No difference between fixed and wireless networks. You don’t have to have an ethernet cable to connect to the web at home either.
This is available only in FDD mode. It is useful in. Explain the function of WDP. It computes the routes when necessary and then maintains them. Since it is a single chip low cost radio based wireless network technology. Explain in detail about access via WAP.
