Computer-aided modeling of spread spectrum packet radio networks

Computer-Aided Modeling of Spread Spectrum Packet Radio Networks

Closed-form expressions for the performance of radio networks are generally not available. For spread spectrum networks, it is not even clear how to represent the underlying network, since the existence of links is heavily dependent on activity in other parts of the network. We have developed a set of computer-based modeling tools to help understand the performance and behavior of these network...

Computer Aided Molecular Modeling Of Membrane Metalloprotease

Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...

Performance Analysis of Spread-Spectrum Packet Networks

The performance of a random access CDMA packet network is analysed in the presence of multiple access interference (MAI). We use a new method based on the improved Gaussian approximation to model the MAI. We evaluate the accuracy of the new method on the bit error probability, packet success probability, throughput and delay.

Throughput enhancement of direct-sequence spread-spectrum packet radio networks by adaptive power control

Absti-ucfThis paper investigates the performance of directsequence spread-spectrum packet radio networks in the presence of the near/far problem. It is found that the maximum throughput of the network suffers degradation due to the near/ far problem. However, analysis also shows that, under high traffic conditions, a network with the near/far problem delivers higher throughput than another with...
