On the applicability of steerable beams in LTE-Advanced networks with high user mobility
(2012)
This article deals with the problem of applying scanning narrow beams to long-term evolution (LTE)-advanced networks that include in their coverage areas fast moving mobiles. The system scenario is assumed to include eNodeBs ...
A novel cache aware routing scheme for Information-Centric Networks
(2014)
Information-Centric Networking (ICN) has attracted the attention of the research community, which has argued that content, instead of end-points, must be at the center stage of attention. The research issues addressed by ...
Dynamic radio resource and interference management for MIMO-OFDMA mobile broadband wireless access systems
(2013)
A multi-user multi-cell Multiple-Input Multiple Output/Orthogonal Frequency Division Multiple Access (MIMO/OFDMA) system for next generation Broadband Wireless Access (BWA) networks is studied, in which the Base Station ...
A modular framework for implementing joint wireless network coding and scheduling algorithms
(2013)
Intersession network coding (NC) can provide significant performance benefits via mixing packets at wireless routers; these benefits are especially pronounced when NC is applied in conjunction with intelligent scheduling. ...
Optimizing Client Association for Load Balancing and Fairness in Millimeter-Wave Wireless Networks
(2015)
Millimeter-wave communications in the 60-GHz band are considered one of the key technologies for enabling multigigabit wireless access. However, the special characteristics of such a band pose major obstacles to the optimal ...
Design and implementation of distributed load balancing and fast handoff for wireless mesh networks
(2015)
The association/handoff procedures are very important towards achieving a balanced operation in 802.11-based wireless mesh networks. In this paper, we design and implement a cooperative association/handoff scheme, where ...
A software framework for alleviating the effects of MAC-aware jamming attacks in wireless access networks
(2011)
The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take ...
XOR-Based Encoding With Instantaneous Decoding for the Broadcast Erasure Channel With Feedback: The Three-User Case
(2014)
We study the case of a three-user broadcast erasure channel with multiple unicast traffic sessions, where feedback from the users is fed back to the transmitter in the form of positive acknowledgment (ACK)/negative ...
Dynamic frequency management in 802.11-based multi-radio wireless networks
(2014)
Efficient channel selection is essential in 802.11 mesh deployments, for minimising contention and interference among co-channel devices and thereby supporting a plurality of quality of service (QoS)-sensitive applications. ...
A content-based publish/subscribe framework for large-scale content delivery
(2013)
The publish/subscribe communication paradigm has become an important architectural style for designing distributed systems and has recently been considered one of the most promising future network architectures that solves ...
