Received signal strength indicator (RSSI) is not suitable for fine-grained indoor applications because of imprecise and unreliable readings caused by multipath fading. This paper presents a simple and robust mechanism to improve RSSI by mitigating multipath fading effects in an indoor environment. Signal analysis is provided to explain the rationale of this method. The proposed method provides instantaneous...
In this paper, we address the issue of transmission power control (TPC) in wireless ad hoc networks. Power control plays an important role in energy saving and network performance enhancement. However, the existing TPC schemes either face the problem of hidden and exposed terminal or have additional hardware requirements. We propose a novel distributed power control protocol, called Receiver Initiated...
In this paper, we propose a cognitive radio-based multi-user resource allocation framework for mobile ad hoc networks using multi-carrier DS CDMA modulation over a frequency-selective fading channel. In particular, given pre-existing communications in the spectrum where the system is operating, in addition to potential narrow-band interference, a channel sensing and estimation mechanism is provided...
