This paper provides an in-depth view on the technologies being considered for Long Term
Evolution-Advanced (LTE-Advanced). First, the evolution from third generation (3G) to fourth …

It is envisioned that next generation wireless network (NGWN) will be heterogeneous where
different radio access technologies coexist. This vision of NGWN has led to the development …

The key feature of future mobile communication systems is the ability to deliver wideband
and high bit-rate multimedia services alongside the traditional radio services such as voice …

We present a new approach to simulated annealing and a new hierarchical algorithm for
row-based placement which has obtained the best results ever reported for a large set of …

The search for the ultimate architecture for cross-layer optimization in cognitive radio
networks is characterized by challenges such as modularity, interpretability, imprecision …

In this paper, an innovative mechanism to perform joint radio resource management (JRRM)
in the context of heterogeneous radio access networks is introduced. In particular, a fuzzy …

In the next generation of heterogeneous wireless networks (HWNs), a large number of
different radio access technologies (RATs) will be integrated into a common network. In this …

Due to the coexistence of different Radio Access Technologies (RATs), Next Generation
Wireless Networks (NGWN) are predicted to be heterogeneous in nature. The coexistence of …

The heterogeneous network concept offers a flexible architecture that allows an efficient
utilization of radio resources by means of Common RRM strategies that ensure a …

This paper presents a novel JRRM strategy based on reinforcement learning mechanisms
that control a fuzzy-neural algorithm to ensure certain QoS constraints. Three RATs (radio …
