A mobile ad hoc network (MANET) is comprised of mobile hosts that communicate with each other using wireless links and based on the peer-to-peer paradigm. A MANET is a selfconfiguring network that can have an arbitrary topology along the time. Each mobile host works as a router and it is free to move randomly and connect to other hosts arbitrarily. Thus, the network topology can change quickly ...

As mobile computing requires more computation as well as communication activities, energy efficiency becomes the most critical issue for battery-operated mobile devices. Specifically, in ad hoc networks where each node is responsible for forwarding neighbor nodes' data packets, care has to be taken not only to reduce the overall energy consumption of all relevant nodes but also to balance indiv...

Many routing protocols for ad hoc networks have been proposed to date. Among them, STAR is a representative table-driven protocol, while AODV and DSR are two representative on-demand protocols. This paper analyzes these three protocols using the GloMoSim simulation environment. The scenarios used in the simulation experiments take into account a variety of environmental factors that influence p...

A network simulator is a software program that imitates the working of computer network. In simulators, the computer network is typically modeled with devices; traffic etc. and the performance are analyzed. Typically, users can then customize the simulator to fulfill their specific analysis needs. This paper gives analysis and comparison study of different wireless network simulators. Simulator...

Network simulation is the most useful and common methodology used to evaluate different network topologies without real world implementation. Network simulators are widely used by the research community to evaluate new theories and hypotheses. There are a number of network simulators, for instance, ns-2, ns-3, OMNET++, SWAN, OPNET, Jist, and GloMoSiM etc. Therefore, the selection of a network s...

The design and evaluation of ad-hoc wireless networks introduce several unique challenges not present in wired network environment. The most significant among them include the communication medium shared between potentially thousands of nodes, the mobility of the network nodes, and the unpredictable nature of the wireless channels with problems such as fading, obstacles and interference. That m...

The focus of this paper is routing in a wide area mobile ad hoc network referred to as a Terminode Network. Our routing scheme is a combination of two protocols: Terminode Local Routing (TLR) and Terminode Remote Routing (TRR). TRR is used for remote destinations. It utilizes the location of a destination obtained by the source using location management or location tracking. TLR acts when the p...

Due to known difficulties of researchers in the networking domain regarding experimentation of their ideas in actual networks, network simulators have become indispensable tools for investigating and validating various ideas in all layers of the network. In this survey, we inspect the implementations of IEEE 802.11 PHY-MAC and propagation models of some of the well-known, open-source network si...
