Introduction

OFDM: a form of MultiCarrier Modulation.
Different symbols are transmitted over different subcarriers
Spectra overlap, but signals are orthogonal.
Example: Rectangular waveform -> Sinc spectrum

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

1. Introduction
Modem mobile phones are small computers, with limited processing power by desktop standards, but power enough to run a small game. If you have a recent phone, you have more processing power in your pocket than ran the Lunar Lander.
Today's phones are also by their very nature networked computers, efficiently sending and receiving digital data. Primarily geared for voice data, they can send and receive other kinds of dat ....etc

Multi-Objective QoS Based Routing Algorithm for Mobile Ad-hocNetworks
Abstract:
Mobile Ad-Hoc NETwork (MANET) is a collection of wireless nodes that can dynamically be set up anywhere and anytime without using any pre-existing network infrastructure. The dynamic topology of the nodes possess more routing challenges in MANET compared to infrastructure based network. Most current routing protocols in MANETs try to achieve a single routing objective using a single route selection metric. As the various routing object ....etc

A near-optimal multi cast scheme for mobile ad hoc networks using a hybrid genetic algorithm
Abstract: Multi cast routing is an effective way to communicate among multiple hosts in a network. It outperforms the basic broadcast strategy by sharing resources along general links, while sending information to a set of predefined multiple destinations concurrently. However, it is vulnerable to component failure in ad hoc network due to the lack of redundancy, multiple paths and multicast tree structure. Tree graph optimization problems (GO ....etc

Abstract
With the increase of usage of wireless networks for purposes where the nodes are either stationary or minimally mobile, focus is also on increasing the network capacity of wireless networks. One such way is to use non-overlapping multiple channels provided by 802.11 by using multiple interfaces per node. Multiple nonoverlapped channels exist in the 2.4GHz and 5GHz spectrum. However, most IEEE 802.11-based multihop ad hoc networks today use only a single channel. As a result, these networks rarely can fully exploit the aggrega ....etc
