DSR (Dynamic Source Routing)

AODV (Ad-hoc On-Demand Distance Vector)

It is a reactive protocol that creates routes between nodes only when they are required. It employs a distance vector technique and keeps track of nodes and their distances in a routing table. It uses sequence numbers to eliminate routing loops and maintain route freshness. One of its advantages is that it makes efficient use of network resources by establishing routes only when necessary. However, the overhead of maintaining the routing table can be significant, especially in bigger networks....

DSR (Dynamic Source Routing)

It is a proactive strategy that plans routes ahead of time. It employs a source routing method and keeps a route cache in order to store previously identified routes. It employs hop-by-hop routing and does not necessitate the updation of a routing table. It has a low overhead because it does not need to constantly update routing tables. However, the higher latency caused by the requirement to determine a packet’s whole path before delivering it can be negative....

Difference between AODV and DSR

Feature AODV DSR Protocol type Proactive Reactive Routing algorithm It uses distance vector algorithm to discover and maintain routes It uses source routing algorithm to determine the entire path of a packet before it is sent Routing table size Smaller routing table size due to the reactive nature  Larger routing table size due to the proactive nature Efficiency It maintains efficient communication between nodes in Mobile and Pervasive Computing It may lead to reduced network efficiency due to unnecessary consumption of network resources Security It is less secure than DSR due to the use of broadcast messages It is more secure than AODV due to the use of source routing Network Load Lower network load due to reactive nature Higher network load due to the proactive nature Advantage It only establishes routes when required so the network resources are used effieciently It reduces overhead, as it does not need to constantly update the routing tables Disadvantage  It causes overhead, as it needs to constantly update the routing tables It reduces network efficiency due to the unnecessary consumption of network resources difference between AODV and DSR?...
