Hotspots providers (using IEEE 802.11 Wireless LAN, also known as WiFi) are looking into ways to increase revenue from their service and improve customer satisfaction/experience. We propose a practical two-hop relaying scheme, managed by the Access Point (AP) to increase aggregate data throughput. We argue that controlled and incentives based collaboration among nodes and AP can improve overall...

Relaying can improve performance of a wireless network, especially when different transmission modes with distance/cost tradeoffs are available. Examples of such modes include data rates or transmission power. This paper geometrically analyzes the probability that a high-cost direct transmission can be replaced by a combination of low-cost relay transmissions. The main result of the analysis is...

This paper analyzes the bit error rate performance of orthogonal frequency-division multiplexing systems in mobile multihop relaying channels. We considered the uplink scenario and quantified the effects of mobile channel impairments such as Doppler shift due to user mobility per hop, high power amplifier distortions when amplifying the transmitted/ relayed orthogonal frequency-division multipl...

This paper considers a full-duplex two-way relaying (FD-TWR) system, where two terminals transmit and receive simultaneously with the help of a full-duplex relay node. We propose the transmission scheme for decode-and-forward (DF) protocol using the differential binary phase-shift keying (DBPSK) modulation to analyse the bit error ratio (BER), which do not need the channel state information (CS...
