Effect of Quality Parameters in Efficient Routing Protocol � Grid FSR with Best QoS Constraints

Abstract

Rapid advanced in information technology has made it possible to transmit the data in wireless links without the aid of any fixed infrastructure or centralized administrator. Wireless mobile ad hoc networks are self-creating, selfadministering and self-organizing entities. Thus a set of selfmotivated mobile wireless users is able to dynamically exchange data among themselves, even in the absence of a predetermined infrastructure and controller. In our research work, we present investigations on the behavior of the Proactive Routing Protocol FSR in the GRID by analysis of various parameters. The Performance metrics that are used to evaluate performance of the routing protocols are Packet Delivery Ratio (PDR), Network Control Overhead, Normalized Overhead, Throughput and Average End to End Delay. Experimental results reveal that FSR is more efficient in Grid FSR in all QOS constraints.FSR can be used in all Resource critical environments. Scalability in respect to QOS is effective in FSR-large area routing protocol. Grid Fisheye state routing (GFSR) consumes less bandwidth by restricting the propagation of routing control messages in paths formed by alternating gateways and neighbor heads, and allowing the gateways to selectively include routing table entries in their control messages.PDR and Throughput are 100% efficient in Simulation Evaluation with NS2.

Simulation and Evaluation of the Performance on Probabilistic Broadcasting in FSR (Fisheye State Routing) Routing Protocol Based on Random Mobility Model in MANET

“…The length of the period affects the performance of this scheme. Short periods could cause collision or contention while long periods may degrade the protocol's ability to cope with mobility [18][19][20]. In this research work Random Waypoint Mobility Model (Bench Mark Mobility Model) is proposed.…”

“…We have used the ns-2 simulator [19] to conduct extensive experiments to evaluate the performance behavior of probabilistic flooding in FSR protocol. The network considered for the performance analysis of the rebroadcast probability vs. density has been varied from 25 nodes up 100 placed randomly on 600 X 600 m2, with each node engaging in communication transmitting within 250m radius and having bandwidth of 2 Mbps.…”
