Performance comparison of routing protocols for AD Hoc networks

Major Goals:
------------

 Till date many routing protocols have been proposed for AD Hoc networks. They are broadly classified into 
 “table driven ” and “on-Demand protocols”. AODV and DSR are two On-Demand routing protocols. This paper 
 would analyze some of these protocols using GloMoSim simulation environment. The scenarios used in simulation 
 experiments take into account are variety of environmental factors that influence protocols performance. 
 The performance is evaluated with respect to fraction of data delivered, routing overhead, average latency in 
 packet delivery and energy consumption. 

Scope:
------

Performance Metrics to be analyzed:

 1. Fraction of Data delivered:
    	The number of Data packets delivered by all nodes during the simulation period.

 2. Packet Drop ratios: 	
  	The number of packets dropped by all nodes during the simulation period.

 3. Routing over head:
    	Number of control packets that are sent by all the nodes to discover and maintain the routes.
 4. Average latency in packet delivery:
    	The average time delay between the time when the data packet is given to the IP-layer at the source node and 
    	the time when the packet arrives the destination IP-layer. This is also called as end-to-end delay.

 5. Energy consumption:
  	The amount of energy required to successfully route the data to the destination, which includes route discovery, 
	route reply, and transmission of the actual data 	and any route error messages if present. 

 6. Density of network: 
    This metric describes the denseness of network. This metric solely depends scenario input parameters. 

 7. Direct connectivity: 
    This is used to show how many other nodes, an average node is in contact with during the simulation.
    
    Parameter 6 and 7 will be evaluated only if sufficient time is available.
 
Scenarios Parameters:
---------------------

 1. Number of nodes in the ad hoc network.
 2. Area over which the nodes will roam.
 3. Mobility of each node.
 4. Pause time.
 5. Node Velocity.
 6. Link layer protocol: 802.11 (2 Mbps).

Expected Outcome:
-----------------

 The simulation results will show the performance of AODV and DSR protocols. 
 This will help us in analyzing the efficiency of the protocol in sparsely and densely connected Network. 
 1. Performance is analyzed in terms of data delivery and packet drop ratio under various scenarios. 
 2. Performance is analyzed in terms of control overhead, which is used in determining and maintaining the routes.
 3. Performance is also analyzed based on power consumption in the network.
