Mobile Ad hoc wireless NETworks (MANETs) that do not need any fixed infrastructure. They are characterized by dynamic topology due to node mobility, limited channel bandwidth, and limited battery power of nodes. The key challenge in the design of ad hoc networks is the development of dynamic routing protocols that can efficiently find routes between two communicating nodes. Thus, many ad hoc routing protocols have been proposed in recent years. All these routing protocols attempt to provide a high data packet delivery ratio and low routing control traffic at the same time. These routing protocols can be classified into three categories: proactive, reactive and hybrid routing protocols.Keywords

Error control codes have become a vital part of modern digital wireless systems, enabling reliable transmission to be achieved over noisy channels. Over the past decade, turbo codes have been widely considered to be the most powerful error control code of practical importance. In the same time scale, mixed voice/data networks have advanced further and the concept of global wireless networks and terrestrial links has emerged. Such networks present the challenge of optimizing error control codes for different channel types, and for the different qualities of service demanded by voice and data. OFDM has become a popular modulation method in high speed wireless communications. By partitioning a wideband fading channel into flat fading narrowband channel, OFDM is used to mitigate the detrimental effects of multi path fading using a simple one-tap equalizer. There is a growing need to quickly transmit information wirelessly and accurately. The end goal is to increase the system throughput while maintaining system performance under a desired bit error rate (BER).
