Device-to-Device (D2D) communications is a key aspect of future 5G cellular networks, as it can help improve spectral efficiency, system capacity, resource utilization, and quality-of-service (QoS), for the overall network. In this paper, a dynamic cross-layer leave-and-join based coalition formation game with non-transferable utility (NTU) is proposed. Our proposed game jointly optimizes mode selection...
In this paper, we study the performance of two cross-layer optimized dynamic routing techniques for radio interference mitigation across multiple coexisting wireless body area networks (BANs), based on real-life measurements. At the network layer, the best route is selected according to channel state information from the physical layer, associated with low duty cycle TDMA at the MAC layer. The routing...
The increase in the number of degrees of freedoms (DoF) that is afforded by multiple-input-multiple-output (MIMO) phased arrays is accompanied by an increase in hardware and computational costs. We mitigate this problem in a collocated MIMO phased array system by employing a selection strategy where a subset of K transmitter-receiver (Tx-Rx) pairs is chosen from the availableN pairs. We formulate...
Device-to-Device (D2D) communications underlaying cellular communications can increase resource utilization, system capacity, and interference, while increasing quality of service (QoS) for cellular and D2D users. In this paper, we design a non-cooperative cross-layer repeated game, which jointly optimizes mode selection (i.e. either operating in cellular mode or reuse mode) at the network layer and...
A game-theoretic method for transmit power control across multi-source–destination distributed wireless networks is proposed, which is viable for any number of source–destination pairs, with any number of players (or sources). A dynamic noncooperative repeated game is proposed to optimize both packet delivery ratio (PDR) and transmit power considering a realistic signal-to-interference-plus-noise...
Coexistence of multiple wireless body area networks (WBAN) is a very challenging problem because each piconet can have a large number of sensors and their movement is unpredictable. Moreover, suitable global coordination schemes do not exist as there is no natural choice of coordinator between piconets. Adaptive schemes that work well with low-occupancy channels, such as listen before transmit, are...
An analytically tractable model for Gaussian multiuser channels with fading is studied, and the capacity region of this model is found to be a good approximation of the capacity region of the original Gaussian network. This work extends the existing body of work on deterministic models for Gaussian multiuser channels to include the physical phenomenon of fading. In particular, it generalizes these...
