A new technique for adapting sip protocol to Ad hoc networks: VNSIP ((Virtual Network for SIP) illustration and evaluation of performance

In the other hand, SIP protocol, which knows a huge booming in internet networks, requires centralized entities, like proxy server, registrar server and location service; consequently SIP is not adapted to Ad Hoc networks. In this paper, we present and evaluate a new technique, which we have called Virtual Network for SIP (VNSIP) to fix the problem related to the constraints of SIP deployment in Ad Hoc network.

Hybrid multi biometric person authentication system

In this paper, the authors present a hybrid multibiometric authentication person system that integrates both multi modal and multi algorithmic. Multi-modal, the system using face and fingerprint features, has long been considered common in personal authentication. Multi-algorithm is the system which uses Circularly Orthogonal Moments, such as Zernike Moment (ZM), Pseudo Zernike Moment (PZM), Polar Cosine Transform (PCT) and Radial Basis Function (RBF) Neural Networks. These moments are widely used because their magnitudes are invariant to image rotation, scaling and noise.

Modeling and simulation of PV array and its performance enhancement using MPPT (P&O) technique

The proposed Perturb and Observe control algorithm is a software programme with a self-tuning function which adjusts the array reference voltage and step size of the voltage to achieve maximum power point. The validity of the photo voltaic module with P & O method allows better performance of MPPT due to variation of both power and voltage. This work is proposed to be carried out in MATLAB/SIMULINK environment.

Scenario based study of on demand reactive routing protocol for ieee 802.11 and 802.15.4 standards

The main method for evaluating the performance of MANETs is simulation. In this paper performance of Ad-hoc On-demand Distance Vector (AODV) reactive routing protocol is studied by considering IEEE 802.11 and IEEE 802.15.4 standards. Metrics like average end-to-end delay, packet delivery ratio, total bytes received and throughput are considered for investigating simulation scenario by varying network size with 10 mps node mobility.
