Discuss any two of them. Generic routing encapsulation allows the encapsulation of packets of one protocol suite mobilr the payload portion of a packet of another protocol suite. What are the two things DSDV adds to the distance vector algorithm?

Write short note on WML Script. Given the lack of complete orthogonality, the transmissions from the more remote mobile units may be more difficult to recover.


What are the three Low Power States provided by Bluetooth? Mmobile is reverse tunneling? The integrating of devices are device- to-device or device-to-server protocol.

The idea of forming groups of piconets called scatternet. Cw2402 are application of pervasive pervasve Where one station is to be heard by others Base Station of mobile network or any other dedicated system polling scheme can be applied. List out the various elements of Bluetooth core protocol. What are the functions offered by WTLS? What is the reaction of standard TCP in case of packet loss?


Users have to interact, this may take some more time. The reverse operation, taking a packet out of the data part of another packet, is called decapsulation.


Native application for the PDA operating system. There are two basic reasons for handover. What are the various issues related to device management and how are they dealt with?

How to improve signal reception by countered cmoputing negative effects of multipath propagation? What are the draw backs of wired networks? Discuss in detail about the access form PCs. What is Jini and what are the services offered by it?

What advantages does the use of IPv6 offer for mobility? What are the general problems of satellite signals traveling from a satellite to a receiver? What are the disadvantages exhibit by WLANs? What are the services offered by Bluetooth?

Typical wireless networks, the station has to move from one access point to another to provide uninterrupted service. What are the problems related to the use of DHCP? Explain the fields of IEEE Specify the fields of minimal encapsulation method in mobile network layer. 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. One digital speech channel is supported.

When the station starts scanning in IEEE Write brief notes on the following. It is a mechanishm, of taking a packet out of the data part of another packet. How do IEEE How is roaming on layer 2 achieved, and how are changes in topology reflected.

M-TCP wants to improve overall throughput, to lower the delay, to maintain end-to-end semantics of TCP, and to provide a more efficient handover. List the different user scenario for wireless piconets. In GSM, authentication uses a challenge-response method: GPRS stands for general packet radio service, it is a more flexible and powerful data transmission technique.


The guard space is used to avoid overlapping with other bursts due to different path delays and to leave the transmitter time to turn on and off.

Discuss about tunneling and encapsulation mechanism and reverse tunneling. To save battery power, a Bluetooth device can go into the one of the three low power states if no data is ready to sent:.

What are all the entities and terminologies needed for understanding Compufing IP? State the three subsystems of GSM. What are the four types of motes available in GSM? What is the purpose of comfort noise generated by physical layer of GSM? Name the advantages and Disadvantages of user acknowledgement in WTP?

Define foot print with respect to satellite systems. Thank you so much!!! This behaviour is called fast retransmit. Give the other terms of pervasive computing. It is used for exchanging signaling messages between L2CAP entities. What are its two modes? The fields in the frame fulfill the following functions:.
