Abstract:

To analyze vehicular Ad-Hoc network routing performance, the GPSR routing performance is studied using network simulation software NS2 compared with traffic simulation software VanetMobiSim. 100 nodes communicated with each other was stimulated by adding routing protocol into NS2, building the environment of simulation, setting simulation parameters and writing TCL script. The data packet delivery path was examined by trace files and GPSR routing performance was concluded through Gawk. The average end-to-end transmission delay trends to increase and the average delivery rate trends to drop whe

Abstract:

AbstractNs2 is an open-source communications network simulator primarily used in research and teaching. Ns2 provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless networks. Although Ns2 is a widely used powerful simulator, it lacks a way to measure networks that are used to assess reliability and performance metrics (e.g., the number of packets transferred from source to destination, delay in packets, packet loss, etc.) and it does not analyse the trace files it produces. The data obtained from the simulations are not straightforward to ana

Abstract:

Standard TCP has lots of problems; for example, the network bandwidth can not give its full play in certain application conditions such as high speed or long distance. High Speed TCP (HSTCP) can solve these problems, but it has serious problems in the fairness of different RTT. Based on the analysis of HSTCP fairness, an algorithm of adding fair factors to improve fairness of HSTCP has been put forward after fairness simulation test by NS2. NS2 simulation experiments prove that this algorithm has greatly reduced the unfairness because of the different RTT.

P2P applications are complex and deployed on a large scale, pure packet level simulations do not scale well enough to analyse P2P applications in a large network with thousands of peers. It is also difficult to assess the effect of application level behavior on the communication system. We therefore propose an approach starting with a more abstract and therefore scalable application level simulation. For the application layer a specific si

Abstract:

The data transfer of wireless sensor network (WSN) can not be separated with routing protocol, Energy efficiency is one of the most important factors in wireless sensor networks. In this paper based on the uneven distribution of the LEACH cluster head and the different lengths and base station communications, we present a improved LEACH algorithm which refers to remaining energy and optimal cluster heads. Computer simulation using NS2 reveals that the proposed protocol reduces the energy consumption compared with the existing LEACH protocol.

Abstract:

Using the TIGER database to create a realistic road map and establishing car following model and lane change model for simulation scene in SUMO. It evaluates the performance of the routing protocols including GPSR, ADOV and DSDR in this scene, and then analyzes their merits and drawbacks in Vehicular Ad-hoc Networks (VANETs) by the simulation of NS2. The results of the analysis show that the GPSR have the best performance in the three kinds of routing protocols. It proved that the protocols based on location information are more appropriate to VANETs. However, it is difficult to meet the needs

Abstract:

For dynamical changed network topology and unstable links, this paper proposes a mobility prediction-based weighted clustering algorithm for vehicular ad-hoc network with high mobility nodes. In the CH election stage, it computes vehicle’s priority through the similarity, intimacy and centrality, the vehicles with the highest priority in their neighborhoods are selected as the CHs, this scheme suitable for large scale network. NS2 simulation results show that the proposed clustering scheme improves the stability of cluster structure, prolongs the CH duration time, improves the delivery ratio.

Abstract:

DV-Hop algorithm is a kind of typical range-free node localization algorithm of wireless sensor network. In order to improve the positioning accuracy of DV-Hop algorithm, in the second stage of DV-Hop localization algorithm, when calculating the average hop distance of unknown nodes, weighting the average hop distance of beacon nodes which is accepted by the unknown nodes, this result is the average hop distance of unknown nodes, the weighted value is determined by the frequency of the unknown nodes received beacon nodes in the first stage. Finally using NS2 simulation tool making a simulation

Abstract:

MANET-IoT networks are currently being focus developed and expected to become popular in next-generation mobile networks due to their simplicity and efficiency in solving real problems in a wide range of areas such as smart agriculture, smart health care, intelligent traffic, military, entertainment, and smart cities. Because of the nature of mobile network nodes, saving energy for MANET is always a complicated problem. In this paper, we proposed a saving energy routing protocol that uses an integrated routing metric from hops number and remaining energy metrics for decision-making to selects

Abstract:

Energy efficiency is a critical issue for sensornetwork. In this paper, we propose an energy efficient context adaptive MAC protocol for wireless sensor networks. The existing approaches try to minimize energy consumption by controlling the duty cycle of transmission period. The New-MAC forecast energy according to the Markov chain, then adjusts the duty cycle through the energy size, then adjusts the duty cycle through the energy size. Computer simulation using NS2 reveals that the proposed protocol significantly reduces the energy consumption compared with the existing S-MAC.
