Scheduling of packet loss and rate of transmission 5. The routers are free to move randomly and organize themselves arbitrarily; thus, the network’s wireless topology may change rapidly and unpredictably. The different types of fading are 1. What is meant by path loss? What is meant by small scale fading? What are the mechanisms used in the MAC layer? Efficient utilization of energy 2.

The frame format of IEEE What is cross layer feedback? Define security routing Security routing is defined as routing the data packets from the source to the destination in ,obile secured manner. Contention based protocols with scheduling mechanisms 4. List the issues of designing a MAC protocol for ad-hoc networks.

These are suitable for emergency situations like natural or human-induced disasters, military conflicts, emergency medical situations, etc.

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.

Enduring end-end resource negotiation 2. Interference Prepared by A. Reservation confirm phase 4. IP switching and Multiprotocol Label Switching. Maximum packet loss rate Prepared by A. Long —distance path loss model ii.

The cross-layer feedback can be categorized as follows Adho to lower layers: The mechanisms used in the MAC layer are 1. Secured routing provides a Confidentiality b Integrity c Avalilability d Non-repudiation 8. They are Prepared by A.

Job Search Job Search. The difference between the effective transmitted power and the received power is called path loss. Minimize Cost per Packet 5. Differentiate proactive and reactive routing protocols. How is application layer integrated with its upper layer? MAC protocol should consider notfs constraint of ad hoc networks for time critical applications c Hidden and exposed terminal problem d Synchronization: Secure routing is done ev2050 wireless channels by having secure routing protocols which support 1.

What is the need for power management in Adhoc network? Hence the cost staffing, etc.


Lower to upper layers: Log In Sign Up. It makes use of frequency modulation to generate radio waves in the ISM band.

Improved channel reuse 4. The reasons that lead to the quick power drain of nodes in mobile Ad hoc network are a Using the same route for a longer duration leads to partitioning of the network. IPv6 – Neighbor discovery, auto-configuration, routing.

This leads to an increase in the overall throughput of the system. Hybrid Protocols attempt to take advantage of best mobipe and proactive schemes.

EC Mobile Adhoc Networks April May Question Paper

Due to certain unique characteristics of ad hoc wireless networks the task of ensuring secure communication in ad hoc wireless networks is difficult. The features of Detection of malicious nodes 2. The Answer is Mobile Ad-hoc Network.
