Network coding is emerging as a promising alternative to traditional content distribution approaches in P2P networks. By allowing information mixture in peers, it simplifies the block scheduling problem, resulting in more efficient data delivery. Existing protocols have validated such advantages assuming altruistic and obedient peers. In this paper, we develop an analytical framework that characterizes...
Wireless mesh networks have emerged as a favorable infrastructure that promises to unify the existing 802.11 wireless LANs. With multiple orthogonal channels and possibly multiple interfaces on the mesh nodes, such networks can provide broadband access for a large number of wireless clients. However, efficient assignment of channels to the available network interfaces has long been a daunting task...
Orthogonal frequency division multiple access (OFDMA) has been integrated into emerging broadband wireless access technologies such as 802.16 wirelessMAN. Due to the diversity of channel gains among the downlink subscribers, it is known that dynamic allocation of subcarriers can significantly improve the overall performance of OFDMA systems, in terms of power efficiency and link throughput. A large...
