Transmit the packet of the remaining node. What do you mean by time to live TTL?

Define Wireless datagram protocol WDP 5. Interference Prepared by A. Explain the contention based protocols with scheduling and reservation in detail. It enables establishment of outdoor high speed radio access networks, providing fixed radio connections to customer premises.

Give the difference between cellular networks and ad hoc wireless networks.

Book Details

What are the major challenges in designing routing protocols? The five phases of FPRP are 1. How does energy aware routing work? Guarantee of correct route discovery 3. The major goals when selecting a routing protocol are a Provide the maximum possible reliability by selecting alternative routes if a node connectivity fails. Discuss the effect of multiple breaks on a single path at the TCP- F sender.


EC Mobile Adhoc Networks Nov Dec Question Paper

It may or may not include the effects of antenna gain. List some of the network layer attacks. Minimize Variance in Node Power Levels 4.

List any two needs of real-time MAC protocol. Explain on demand routing protocol in detail. This protocol attempt fc2050 evaluate continuously the routes within the network, so that when a packet needs to be forwarded, the router is already known and can be immediately used. Differentiate proactive and mobie routing protocols. On-demand routing protocols – No periodic exchange of routing information.

Factors influencing small scale fading are a Speed of surrounding objects b Multipath propagation c Speed of the mobile d Transmission bandwidth of the signal. List the five phases of FPRP. Comment on the use of natural language passwords directly for cryptographic algorithms.

List the major classification of routing protocol for ad hoc wireless network. 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. The classification of routing protocols based on the routing information update mechanism are 1. Detection of malicious nodes 2.

What are the two types of protocols used to handle multiple access issues? List the classification of routing ahoc based on the routing information update mechanism. Temporal stability is determined based on number of beacon signal that node receives from its neighbors. Explain with an example. Network layer solution for QoS is used for 1. The services provided by IEEE List the issues in designing a transport layer protocol for Ad hoc wireless networks.

What is the impact of the failure of proxy nodes in split- TCP? With any five major reasons, analyze why TCP is exposed to significant throughput aadhoc in ad hoc networks.
