This paper proposes an Energy Aware Routing Protocol (E-AODV) based on AODV which incorporates local routing of intermediate nodes to increase the lifetime of the network .NS2 (Version 2.34) [1] simulator is used for the simulation of new protocol and AODV protocol for the performance parameters packet delivery ratio and delay. This implementation demonstrates that how small changes in the prin...

Network algorithms are deployed on large networks, and proper algorithm evaluation is necessary to avoid large-scale outages or performance bottlenecks.However, evaluating a network algorithm in a simulator results in significant run timeswhich scale poorly as we increase the number of routers. An alternative network simulator design is desired which scales significantly better than current sim...

The group key management technique is an important for cryptographic applications. In this paper, we implemented our proposed method [1] on a protocol communication. authenticated distribution mechanism distributing key. We also discussed security analysis and attacks in active passive adversary model. Also, it ensures semantic as well Key freshness of the Along with this, they provide implicit...

This article analyzes the performance of vertical handover between UMTS and WiMAX networks by defining development architecture for supporting mobility between these two technologies. First, architectures and principles of operation of networks UMTS and WiMAX are detailed and compared. Then the main protocols of mobility are considered as support of handover between UMTS and WiMAX (802.16). Fin...

We present a new iterative mathematical model for calculating the average bandwidth assigned to traffic flows using a Weighted Round Robin with Priority queuing (WRRPQ) scheduler with both strict and rate controlled priority in IP based NGN networks. The bandwidth assignment estimation is based on the average packet length, link speed and the arrival rate. We prove the model outcome with exampl...

In this paper, we study the incremental deployability of the CoreStateless Fair Queuing (CSFQ) approach to provide fair rate allocations in backbone networks. We define incremental deployability as the ability of the approach to gracefully provide increasingly better quality of service with each additional QoS-aware router deployed in the network. We use the ns2 network simulator for the simula...

AODV protocol is an on demand reactive protocol, which exhibits congestion during high mobility and multiple data packet stream to a common destination. This may result in decaying the performance of AODV. The proposed modification is aim controlled congestion by applying efficient local route repair method. When the link failure is detected at intermediate node, a help message has broadcasts t...

Vehicular Ad-Hoc Networks (VANETs) have recently gained considerable attention from both research and industry communities. One of the challenges posed by the study of VANETs is the definition of routing protocols design. In this paper, a realistic simulation environment is developed based on Mobility model generator for Vehicular networks (MOVE) and Network Simulator (NS2). The performance of ...

This paper presents a uniform clustering approach which aims to cover entire field with identical clusters scattered over the field. The Cluster head is elected using the LEACH protocol for every cluster locally. Both LEACH and I-LEACH (Identical clustering LEACH) were compared through extensive simulations using NS2 simulator which shows that I-LEACH performs better than LEACH protocol. I-LEAC...

509 Abstract—Algorithms used for scheduling play a major role in providing quality of service in video streaming. This paper describes a simulation environment that has been designed combining network simulator ns2 with video codec to predict the quality of service. Virtual clock scheduling algorithm has been applied to evaluate the performance metrics and compared with the weighted round robin...
