Communication networks are often designed and analyzed assuming tight synchronization among nodes.

Due to the limited energy supplies of nodes, in many applications like wireless sensor networks energy-efficiency is crucial for extending the lifetime of these networks.

Device-to-device (D2D) communications facilitate promising solutions for service optimization and spectrum/capacity efficiency in the Third-Generation Partnership Project (3GPP) networks.

We introduce two novel data transfer primitives for weakly connected laptops that can be switched off frequently and have intermittent network access.

Communication can consume a significant fraction of the available energy for many simple sensor devices for which battery life is an important consideration in deployment.

Access networks, in particular, Digital Subscriber Line (DSL) equipment, are a significant source of energy consumption for wireline operators.

As future networks aim to meet the ever-increasing requirements of high data rate applications, dense and heterogeneous networks (HetNets) will be deployed to provide better coverage and throughput

In this paper, we exploit the benefits of the diversity gains that arise from a cluster of opportunistic relays (ORs) and from the independently fading subcarriers of multiple users.

We consider the problem of minimizing the power consumption of IP core networks by means of power aware design and auto configuration of the Points of Presence (PoPs), given general traffic demands
