The features of wireless LAN are a Power management to save the battery power. How is routing table constructed in fisheye state routing protocol? What do you mean by contention based protocols?

Why does TCP not work well in ad hoc network? List the major security threats that exist in ad hoc wireless networks.


Collaborative and distributed computing c. Give the classifications of MAC protocols.

It represents signal attenuation as a positive quantity measured in db. Design goals of a MAC protocol for ad-hoc networks are a The networ,s of the protocol should be distributed. Reservation confirm phase 4.


Discuss briefly cross layer optimization technique in detail. Reflection causes a phase shift of shadowing. Based on the routing topology how the routing protocols are classified? Distinguish between shadowing and reflection of signal propagation.

Increase in overall capacity of the channel This protocol invoke a route determination procedure only on demand. State the use of embedded protocol boosters in cross-layer optimization.

List the challenges faced by WLAN industry. Cross-layer feedback means interaction among the layers in the protocol stack.

Give the classification of contention based protocol. Efficient utilization of energy 2.

Book Details

The features that are not supported by the traditional TCP for handling adhoc network are networkss. List the characteristics of ideal routing protocol for ad hoc wireless network. Path break handling mechanisms 4. What are the parameter optimization techniques available? List the table driven protocols.

How on-demand routing protocols differ from on-demand routing protocols? This leads to an arhoc in the overall throughput of the system. It employs radio frequency technology for communication. Mobility of nodes in a sparsely populated mobile ad ho network is less.
