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

Abstract

Broadcasting in MANETs has traditionally based on flooding, which simply swamps the network with large number of rebroadcast messages in order to reach all network nodes. Although probabilistic flooding has been one of the earliest suggested schemes to broadcasting, there has not been so far any attempt to analyze its performance behavior in a MANET environment. In an effort to fill this gap, this paper investigates using extensive NS-2 simulations the effects of a number of important system parameters in a typical MANET, including node speed, pause time, and node density and packet reach ability on the performance of probabilistic flooding. The results reveal that most of these parameters have a critical impact on the reach ability and the number of saved rebroadcast messages achieved by probabilistic flooding on FSR (Fisheye State Routing) Protocol. The Random way Point Mobility model is selected as the mobile ad hoc network mobility model in NS2 Simulation.

Routing and Scheduling Issues in Vehicular Ad-hoc Networks

“…FSR uses "Fisheye" technique, the size of the information required to represents the graphical data is reduces and only relevant information is only stored. Fisheye captures the accurate data near the focal point with great accuracy but as the distance from the focal point expands the amount of captured details also decreases [13].…”

A survey on proactive routing protocols in MANETs

“…Thereby each node can have the appropriate information regarding its neighbor nodes accurately. Hence the information minimize the rate of traffic for transmitting the update messages [13]. In fig: 7, it depicts that the inner nodes as hop count 1 nodes the middle nodes are hop count 2 nodes and outer most as hop count 3.Therefore the inner nodes chooses nodes with least count as hop node to update its information [13].…”

Towards scalable routing for wireless multi-hop networks

“…As a link-state routing protocol, the FSR protocol maintains a topology map of the network at each node. However, instead of flooding a network change when such is detected, it proposes a different scheme for information dissemination [Sivakumar and Chelliah, 2012].…”
