Draw the frame format of IEEE List the transmission impediments of wireless channel.
Doppler Shift Transmission rate constraints What are the mechanisms used in the MAC layer? Cross-layer feedback means interaction among the layers in the protocol stack.
The routing protocols may also be categorized as follows: The Answer is Mobile Ad-hoc Network. Propagation model which is used to predict received signal strength, when the adhco path is unobstructed between transmitter and receiver is called free space propagation model. This union forms a random topology. Path break handling mechanisms 4.
Anna University ECE 8th Semester Notes – Site Title
How is application layer integrated with its upper layer? Reflection causes a phase shift of shadowing. Improving channel utilization 6.
What is protocol optimizer? List any two needs of real-time MAC protocol.
Maximum packet loss rate Prepared by A. It is the best metric only in the shortest path protocol.

The frame format of IEEE What are the factors that affect effective cross layer design? A “mobile ad hoc network” MANET is an autonomous system of mobile routers and associated hosts connected by wireless links –the union of which form an arbitrary graph.
HRMA SRMA A multichannel MAC protocol which is based on half-duplex, very slow TDMA frame based dynamic reservation 1 frequency-hopping spread spectrum MAC protocol FHSS radios Time slot reservation protocol where each Nodes are allocated different time slots so 2 fixed aehoc slot is assigned a frequency that transmissions are collision free channel Uses a reservation and handshake mechanism to enable a pair of Nodes use a collision-avoidance 3 communicating nodes to reserve a handshake mechanism and a soft frequency hop, thereby guaranteeing reservation mechanism collision-free data transmission Developed with the main objective of supporting integrated services of real-time notss Supports real time transmission and non-real-time application in ad hoc networks The features of This is done by manipulating multiple queues at every node, one each for each data stream, and running the back-off algorithm independently for each queue.
Interference Prepared by A. Lower to upper layers: Hence the cost staffing, etc.
Objectives and methods of Control. What are the different types of conflict free protocols? Improved channel reuse 4.
Mobile Ad Hoc Networks – .
Table driven routing protocols – Periodic exchange of routing information. What is the need for cross layer design? Minimize Variance in Node Power Levels 4. Fundamentals of Data Structure. List the advantages and disadvantages of DSDV routing protocols.
Log In Sign Up. This is called scattering. Enduring end-end resource negotiation 2. The presence of dynamic and adaptive routing protocols enables quick formation of ad hoc networks and is mobjle for emergency situations like natural disasters, spontaneous meetings or military conflicts.
