Advances in wireless technology and portable computing along with demands for greater user mobility have provided a major movement towards development of ad-hoc networks. The main Method for evaluating the performance of MANET’s is simulation. An extensive simulation is performed using NS-2 simulator and end to end delay, packet delivery ratio, packet loss ratio, throughput and jitter for React...

In this paper we presents a method for handling multiple metrics and different network parameters simultaneously to analyze the loss factor of routing protocols in mobile ad hoc network(MANET) environments. We have used Taguchi’ loss function to determine the best parameters giving maximum throughput, packet delivery ratio (PDR), average delay, DROP and routing over head simultaneously for AODV...

In a cognitive radio network (CRN), a preempted secondary user (SU) is placed in a call level queue to wait for accessing another free channel. If the availability of channels is transparent to SUs, packets will be generated during their waiting time and the performance of the CRN will be influenced by which way to handle these packets. This paper mainly analyzes the performance of a CRN adopti...

A multistage vector quantizer (MSVQ) based coding system is source-channel optimized for packet networks. Resilience to packet loss is enhanced by a proposed interleaving approach that ensures that a single lost packet only eliminates a subset of the vector stages. The design is optimized while taking into account compression efficiency, packet loss rate, and the interleaving technique in use. ...

Existing mobility support models in cellular communications misinterpret mobility loss in cellular networks as congestion loss, thus it degrades the performance by invoking unnecessary congestion control action. In this paper, we investigated the performance of Double Buffer Technique (DBT) model for mobility support in wireless IP networks. The DBT model uses the END message and the TQRS timer...

In this paper, we have performed a comparative analysis on three different MANET protocols with respect to packet delivery ratio (PDR), throughput, average end-to-end delay, routing overhead, normalized routing load (NRL), packet drop and packet loss metrics. The protocols considered are DSR, AODV and DSDV. The first two protocols fall under reactive whereas the third one is a proactive protoco...

In this paper, we consider packet switching problems in bipartite concentrators under the assumption that more than one packet/slot can be processed through a fabric crosspoint. We use three packet-processing models to derive the packet loss and throughput in a bipartite concentrator. The following paper is an extended summary which presents the models and main results. We expect to provide a m...
