Consider a switched queueing network with general routing among its queues. The MaxWeight policy assigns available service by maximizing the objective function ∑jQjσj among the different feasible service options, where Qj denotes queue size and σj denotes the ...

We present PC-RPL, a transmission power-controlled IPv6 routing protocol for low-power and lossy wireless networks that significantly improves the end-to-end packet delivery performance under heavy traffic compared to the standard RPL. We show through ...

In contemporary cellular systems, end users near cell edges experience inferior data rates; this is because of falling signal strength and increased interference from neighboring cells. Low-cost relays have been proposed to provide near-equitable data ...

A typical Wireless Sensor Network (WSN) uses multihop communication rather than direct transmission. In a multi-hop communication, the sensor node communicates the sensed data to its neighbor node, which is comparatively closer to the sink and ...

In multi-hop cognitive radio networks, it is a challenge to improve the energy efficiency of the radio nodes. To address this challenge, in this paper, we propose a two-level Stackelberg game model, where the primary users and the secondary users act as ...

In a multihop ad hoc network, end-to-end data transmissions traverse through multiple inter-node wireless links. A jammer can disrupt the entire data transfer of a network by intentionally interfering with links between a subset of nodes. The impact of ...

The application of wireless sensor networks is gradually gaining popularity in ubiquitous computing. They are used for military surveillance, home automation and monitoring, underwater surveillance, wearable sensor and many others. With their way of ...

Agile providing Internet connectivity to the victims right after a disaster occurs is essential to mitigate loss and save people. It is hard, however, to quickly recover communication infrastructures due to many difficulties such as reach ability to the ...

Multihop cooperative communication is emerging as a key concept to extend the coverage area of the network and potentially increase the capacity. The spectral efficiency of such networks can be improved by adapting the transmission to time-varying ...

To address the problem of information spreading over lossy communication channels, this paper proposes a joint FoUntain coding and Network coding (FUN) approach. Different from the Transmission Control Protocol (TCP), our FUN approach is a mechanism of ...

As with the cases of other works in routing protocols of wireless sensor networks, the focus of this research is power efficiency and thus achieving increased network lifetime so that the sensor network can be used for a longer period of time. Here we ...

We present randomized distributed algorithms for connectivity and aggregation in multi-hop wireless networks under the SINR model. The connectivity problem asks for a set of links that strongly connect a given set of wireless nodes, along with an ...

Although existing flooding protocols can provide efficient and reliable communication in wireless sensor networks on some level, further performance improvement has been hampered by the assumption of link independence, which requires costly ...

Green internet of things are investigated by studying energy-efficiency in wireless sensor networks. A cooperative multihop data transmission approach is presented and analyzed. Significant energy savings are achieved with the proposed approach compared ...

Complex interference in static multihop wireless mesh networks can adversely affect transport protocol performance. Since TCP does not explicitly account for this, starvation and unfairness can result from the use of TCP over such networks. In this ...

A cross-layer design along with an optimal resource allocation framework is formulated for wireless fading networks, where the nodes are allowed to perform network coding. The aim is to jointly optimize end-to-end transport-layer rates, network code ...

Cities worldwide have planned and implemented large-scale wireless mesh network (WMN) deployments. These mesh deployments are expected to provide broadband mobile access to the Internet at a low cost to the user. This paper considers the fairness ...

Recent advances in the physical layer have enabled the simultaneous reception of multiple packets by a node in wireless networks. We address the throughput optimization problem in wireless networks that support multipacket reception (MPR) capability. ...

As the increase of data traffic is expected to grow faster than wireless capacity, dealing with congestion is unavoidable in the future. The capacity imbalance between wired and wireless links leaves a bottleneck on the wireless link while traffic keeps ...

In this paper, we propose a multihop ACK-based greedy forwarding (MAGF) scheme that considers the asymmetrical reliability of wireless links in order to improve the reliability and efficiency of packet transmissions. Existing greedy forwarding schemes ...
