We analyze Coordinated Multi-Point (CoMP) transmission and reception over heterogeneous wireless networks (HetNets). Our focus is on the design of a practical algorithm for joint resource allocation (joint scheduling) in each HetNet cluster. We present one such algorithm together with its detailed analysis and evaluation under two different approaches for obtaining and utilizing channel feedback […]
Read moreThe roof of an automobile would appear to be an ideal platform to place multiple-input-multiple-output (MIMO) antennas, having a large ground plane with plenty of space to separate antennas for optimum embedded element radiation efficiency. However, styling concerns often require that the antennas are to be placed close together. Thus, mutual coupling plays an important […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications
Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared to waiting […]

A stochastic geometry analysis of inter-user interference in IEEE 802.15.6 body sensor networks
Inter-user interference deteriorates reliable communication in body sensor networks (BSNs) when multiple BSNs are transmitting simultaneously in close proximity to each other. Stochastic geometry provides a natural way of modeling the placement of interferers, by averaging over all potential geometrical realizations for the interferers. This paper presents a stochastic geometry analysis of inter-user interference in IEEE 802.15.6 BSNs. The […]
Read moreNetwork-on-chip (NoC) has emerged as a vital factor that determines the performance and power consumption of many-core systems. This paper proposes a hybrid scheme for NoCs, which aims at obtaining low latency and low power consumption. In the presented hybrid scheme, a novel switching mechanism, called virtual circuit switching, is proposed to intermingle with circuit […]
Read moreIn this paper, we describe dynamic unicast to increase communication efficiency in opportunistic Information-centric networks. The approach is based on broadcast requests to quickly find content and dynamically creating unicast links to content sources without the need of neighbor discovery. The links are kept temporarily as long as they deliver content and are quickly removed […]

Minimization of CSI Feedback Dimension for Interference Alignment in MIMO Interference Multicast Networks
It is well-known that interference alignment (IA) can achieve substantial theoretical gains in multiple-input multiple-output (MIMO) networks. However, the conventional works usually assume the full channel state information (CSI) is available at the transmitter side, which would create a overwhelming CSI feedback overhead for practical frequency-division duplexing (FDD) wireless systems. To implement IA in practice, […]
Read moreNetwork on Chip (NoC) has been envisioned as a scalable fabric for many core chips. However, NoCs can consume a considerable share of chip power. Moreover, diverse applications are executed in these multicore, where each application imposes a unique load on the NoC. To realise a NoC which is Energy and Delay efficient, we propose […]
Read moreSoftware-defined deployments are growing into data center and enterprise network infrastructures. The typical promises of software-defined networks (SDN) are improved time for market, decreased risk and operational costs for services, flexibility and unified management. However, little is known and shared about how to actually manage an SDN network, especially in localising underperforming network paths (what […]
Read moreConfiguring range based packet classification rules in network switches is crucial to all network core functionalities, such as firewalls and routing. However, OpenFlow, the leading management protocol for SDN switches, lacks the interface to configure range rules directly and only provides mask based rules, named flow entries. In this work we present, ORange, the first […]
