JNTU B.Tech IV ADHOC AND SENSOR NETWORKS Previous Question Paper (May - 2019 - R15)
Note: This question paper contains two parts A and B. Part A is compulsory which carries 25 marks. Answer all questions in Part A. Part B consists of 5 Units. Answer any one full question from each unit. Each question carries 10 marks.
PART - A
What is Multipoint Relay?
Answer
A Multipoint Relay (MPR) is a node selected by a neighbor to forward broadcast packets in the Optimized Link State Routing (OLSR) protocol. MPRs are chosen to cover all nodes two hops away, significantly reducing redundant transmissions during flooding.
What are the features of Cluster Head Gateway Switch routing protocol?
Answer
The Cluster Head Gateway Switch Routing (CGSR) protocol features include:
- Hierarchical network structure using cluster heads to manage routing.
- Use of a gateway node to connect different clusters.
- Token-based scheduling to reduce contention and collisions within the cluster.
Explain how to classify the Multicast routing protocol.
