Performance Enhancement of TORA by Node Density and Mobility Speed.
1.
2. • What is MANET?
• Network of mobile devices that
are connected without wires
• Ad hoc network does not rely on
any fixed
• There is no access points or base stations
3. • Why is this routing protocol
are chosen?
• Based on concept of link
reversal
• Temporary Ordered Routing
Protocol (TORA)
• Has 3 basic function
• Route Creation
• Route Maintenance
• Route Erase
4. • People that are getting hit by natural
disaster can’t connect with the people out
of the coverage
• Network topology changes frequently and
unpredictable
• Lack of centralized entity
5. • To study TORA routing protocol in MANET.
• To modify the parameters that are affected
the network performances such as node
density and mobility speed.
• To analyze the performances of TORA in
terms of throughput, packet delivery ratio
and packet loss rate.
6. • To study about TORA in MANET
• To use the NS2 Simulation tool
7. • Timing of study
• Lack of previous research studies about
TORA

Type
Link Reversal Shortest and updated path Shortest and updated path Link State Unicast multipath
routes
Shortest path
Routing table Directed Acyclic Graph (DAG) Maintain a node table which
is the next hop routing
information for the
destination nodes is stored
The route is created only
when it is required and the
nodes utilize the route cache
information efficiently to
reduce the overhead and
collision.
Node maintain a complete
address to each destination

Process
1. Hop by hop

2. End to end

Nodes maintain a routing
table
Peforms route
discovery for the
destination when
receive RERR message
Nodes maintain a
routing table which
is used to determine
the next hop to
reach the
destinations
Limitations Overhead in large network
consume a large bandwidth
Multiple Route Reply packets
in response to a single Route
Request packet can lead to
heavy control overhead
Scalability problems due to
the source routing and
flooding
High overhead, does not
support multipath routing
Increasing the size of
the routing packets
Nodes will spending
a lot of time
converging to a
cluster head if the
cluster head is
changed frequently
