Abstract-To combat the challenges(the mismatch between throughput and layer delivery ratio, the useless packets in high layers due to the loss of packets in low layers) brought by the layered encoding to data scheduling for P2P streaming in the mobile network, We propose a new data scheduling scheme, named MLayerP2P. The key idea of the MLayerP2P is: A(More)
This paper addresses the cross-tier interference mitigation problem using power allocation in two-tier OFDMA femtocell networks. We formulate the power allocation problem as a dual-utility hierarchical (Stackelberg) game with a leader-follower approach. The leaders (macrocells) foresight the response of followers (femtocells), and maximize their individual(More)
This paper addresses how to optimize the radio coverage area of OFDMA femtocell networks in enterprise deployment. Considering some basic requirements of coverage, including coverage holes, coverage overlaps, area spectral efficiency (ASE) and load balancing, the coverage optimization problem is modeled as a Multiple Attribute Decision Making (MADM)(More)
In IEEE802.11-based wireless multi-hop Ad hoc networks nodes need to contend for the shared wireless channel, which could result in congestions and waste the limited wireless bandwidth resource. A novel adaptive backoff algorithm based on network congestion-NCBAB (Network-Congestion Based Adaptive Backoff) in media access control (MAC) layer is proposed. In(More)
Dense deployment of small cell in heterogeneous networks (HetNet) is considered as a promising way to cope with the exponential growth in mobile traffic demand. In such scenario, coverage optimization is a challenge due to the unplanned deployment and plug-and-play feature of small cell. In this paper, the coverage performance of the network is analyzed(More)
