Network Simulator (NS3) tool is an event driven simulator and it is simple to utilize this tool for wireless network. In Wireless network energy consumption is the main issue, where energy is drained by the node while transmitting data. Nodes are typically not connected to the infrastructure and should consequently undergo as long as possible without recharging. The pervasiveness of wireless networks...
Wireless internet has become popular in recent years due to the tremendous growth in the number of mobile computing devices and high demand for continuous network connectivity regardless of physical locations. In this paper, we investigate the effects of routing protocols on the performance of Transmission Control Protocol (TCP) variants in multi-hop wireless networks. Through simulations we study...
This paper investigates congestion behavior of TCP and its variants TCP Reno, TCP NewReno, TCP Sack1, TCP Vegas, TCP Rbp and TCP Fack for AODV (Ad hoc Ondemand Distance Vector) and DSR (Dynamic Source Routing) routing protocols under persistent packet reordering attack through simulations in NS-2. It also proposes a solution to counter misinterpretation packet reordering with packet loss when retransmissions...
A vehicular ad hoc network (VANET) is an autonomous system of vehicle nodes are connected by wireless links. The routers are free to move randomly and organize themselves arbitrarily; thus, the network's wireless topology may change rapidly and unpredictably. Such a network may operate in a standalone fashion, or may be connected to the Internet. Multi hop, mobility, large network size combined with...
