An area-based overlay architecture for scalable integration of sensor networks
(2010)With many different sensor networks being deployed, there will be an increased need to facilitate their uniform and efficient access at a large, perhaps even global, scale. To this end, we present an overlay-based architecture ... -
Auction mechanisms for network resource allocation
(2010)In the autonomic Internet of the future, auction mechanisms arise as key methods for realizing efficient resource allocation. The major asset of auctions is their obliviousness to node utilities, which renders them capable ... -
Backbone formation in military multi-layer ad hoc networks using complex network concepts
(2016)Modern battlefields are characterized by increasing deployment of ad hoc communications among allied entities. These networks can be seen as a complex multi-layer ad hoc network, where each layer may be an independently ... -
Backbones for Internet of Battlefield Things
(2021)The Internet of Battlefield Things is a relatively new cyberphysical system and even though it shares a lot of concepts from the Internet of Things and wireless ad hoc networking in general, a lot of research is required ... -
Client and server games in peer-to-peer networks
(2009)We consider a content sharing network of noncooperative peers. The strategy set of each peer comprises, (i) client strategies, namely feasible request load splits to servers, and (ii) server strategies, namely scheduling ... -
Cooperation and directionality: A co-opdirectional MAC for wireless ad hoc networks
(2007)Advances in cooperative communications and directional antenna design so far have taken place in parallel, if not in isolation from each other. To explore the role they may play in the next generation of wireless networks, ... -
A demonstration of video over a user centric prioritization scheme for wireless LANs
(2008)Due to the unreliable nature of the wireless medium, provisioning of the Quality of Service (QoS) in wireless LANs is by far more complicated than in wired networks. In this demo we show the efficiency of a new QoS support ... -
Detecting IEEE 802.11 MAC layer misbehavior in ad hoc networks: Robust strategies against individual and colluding attackers
(2007)Selfish behavior at the Medium Access (MAC) Layer can have devastating side effects on the performance of wireless networks, with effects similar to those of Denial of Service (DoS) attacks. In this paper we consider the ... -
Distribute, store and retrieve management policies in wireless ad-hoc networks using the content delivery publish/subscribe paradigm
(2009)Policy management is a management paradigm that has been extensively studied for the case of fixed networks but limited work can be found for migrating it to mobile environments. It enables dynamic adaptation of the network ... -
Distributed algorithms for multi-layer connected edge dominating sets
(2019)Monitoring the state of communications in a distributed multilayer network with differing node capabilities requires the maintenance of a backbone which is a connected edge dominating set. In this letter, we present ... -
Downlink multi-user transmission for higher user speeds in IEEE 802.16m
(2009)A dynamic resource allocation algorithm with beam steering is evaluated for providing broadband wireless access to mobile users of the emerging IEEE 802.16m air interface standard. Thanks to our design, the coverage area ... -
Generalized indexing for energy-efficient access to partially ordered broadcast data in wireless networks
(2006)Energy conservation and access efficiency are two fundamental though competing goals in broadcast wireless networks. To tackle the energy penalty from sequential searching, the interleaving of index with data items has ... -
Handling asymmetry in gain in directional antenna equipped ad hoc networks
(2005)The deployment of traditional higher layer protocols (especially the IEEE 802.11 MAC protocol at the MAC layer) with directional antennae could lead to problems from an increased number of collisions; this effect is primarily ... -
Impact of optimal MAC layer attacks on the network layer
(2006)Node misbehavior in wireless ad hoc networks leads to sudden unpredictable changes in network topology, resulting in fluctuation of traffic load and capacity for already existing links. In this work we consider node ... -
Joint beamforming and channel selection for multicast IEEE 802.11n WLANs
(2008)Multicast transmission over WLANs is becoming a popular application. IEEE 802.11n technology is developed due to the ever increasing demand for higher data rate and Quality of Service (QoS). However, there is an unmanaged ... -
Low complexity algorithms for relay selection and power control in interference-limited environments
(2010)We consider an interference-limited wireless network, where multiple source-destination pairs compete for the same pool of relay nodes. In an attempt to maximize the sum rate of the system, we address the joint problem of ... -
Measurement aggregation and routing techniques for energy-efficient estimation in wireless sensor networks
(2010)Wireless sensor networks are fundamentally different from other wireless networks due to energy constraints and spatial correlation among sensor measurements. Mechanisms that efficiently compress and transport sensor data ... -
