Robust vehicle suspension system by converting active and passive control of a vehicle to semi-active control ystem analytically
This research article deals with a simplified translational model of an automotive suspension system which is constructed by considering the translation motion of one wheel of a car. Passive Vehicle Suspension System is converted into Semi Active Vehicle System. Major advantage achieved by this system is that it adjusts the damping of the suspension system without the application of any actuator by using MATLAB® simulations. The semi-active control is found to control the vibration of suspension system very well
DSDV, DYMO, OLSR: Link Duration and Path Stability
In this paper, we evaluate and compare the impact of link duration and path
stability of routing protocols; Destination Sequence Distance vector (DSDV),
Dynamic MANET On- Demand (DYMO) and Optimized Link State Routing (OLSR) at
different number of connections and node density. In order to improve the
efficiency of selected protocols; we enhance DYMO and OLSR. Simulation and
comparison of both default and enhanced routing protocols is carried out under
the performance parameters; Packet Delivery Ratio (PDR), Average End-to End
Delay (AE2ED) and Normalized Routing Overhead (NRO). From the results, we
observe that DYMO performs better than DSDV, MOD-OLSR and OLSR in terms of PDR,
AE2ED, link duration and path stability at the cost of high value of NRO
On Link Availability Probability of Routing Protocols for Urban Scenario in VANETs
This paper presents the link availability probability. We evaluate and
compare the link availability probability for routing protocols; Ad hoc
On-demand Distance vector (AODV), Dynamic Source Routing (DSR) and Fisheye
State Routing (FSR) for different number of connections and node density. A
novel contribution of this work is enhancement in existing parameters of
routing protocols; AODV, DSR and FSR as MOD-AODV, MOD-DSR and MOD-FSR. From the
results, we observe that MOD-DSR and DSR outperform MOD-AODV, AODV, MODOLSR and
OLSR in terms of Packet Delivery Ratio (PDR), Average End-to End Delay (AE2ED),
link availability probability at the cost of high value of Normalized Routing
Overhead (NRO).Comment: IEEE Conference on Open Systems (ICOS2012)", Kuala Lumpur, Malaysia,
