Learn how your comment data is processed. Explain the architecture of IEEE Draw the packet frame format of WATM. The network makes the handoff decision based on reports from the MS. Nltes any to table driven routing protocols in ad-hoc networks. The services of security can be classified in the following categories: Explain in detail roaming support in wireless network.


List the two major states in the operation of Bluetooth. Explain the principle, frame structures nofes working of TDMA system. MANET can be defined as an autonomous system of nodes or MSs also serving as routers connected by wireless links, the union of which forms a communication network modeled in the form of an arbitrary communication graph.

List the two types of schemes available to allocate a single broadcast networ,s among competing nodes. List the units components that involved in setting up a call. Compare hierarchical routing and flat routing in sensor networks.

List the four layers involved in SMS. What are hybrid protocols? List the groups made by random access methods for mobile data services?

On what parameters Handoff depends on? Explain in detail about IEEE These resources are used for data services which does not require severe delay.


List the challenges faced by WLAN industry. Here you will get notes for all units. List the features of wireless LAN. What wlreless the limitations of GPRS? Secure system can be defined as one where as intruder has to spend an unacceptable amount of time and effort in interpreting the system. Explain MAC layer challenges in wireless sensor networks in detail. Explain the IEEE Determine the transfer time of a 20 kB file with a mobile data network with the transmission rate of 10 Kbps.

Compute the maximum throughput of a pure ALOHA networking with a large number of users nerworks transmission rate of 1 Mbps? Design a WLAN for an office building based on statistical models with certain information provided. The strongest packet will be transmitted. From a handoff perspective it is important that, a free channel is ec20433 in a new cell whenever handoff occurs, so that undisrupted service is available.


What is the purpose of developing the second generation systems? What is the frequency band and channel bandwidth specification of WiMax Standard?

List the services provided by IEEE What are the characteristics of DSSS?

Transmission resources are wasted if there wureless no voice transmission. EC Wireless Networks 8. Your email address will not be published. Due to fading, packets from different transmitting stations can arrive with different transmitting power values. Mention some key factors that contribute to security problems in wireless networks.

Electronics and Communication Engineering Notes witeless the semester are available here. A MS does this by storing the phone number or the number used to contact the MSpersonal identification number for the station, authentication parameters, and so on in the SIM card.
