The basic idea behind cooperative communications is that mobile terminals collaborate to send data to each other. This effectively adds diversity in the system and improves the overall performance. In this paper, we investigate the potential gains of cooperative communication in future home networks. We derive analytical expressions for the error probability of binary phase shift keying (BPSK) signals over Nakagami-m fading channels in a multi relay communication network. Following to the analytical study, we analyze the contribution of cooperative relaying to the 60GHz network connectivity through simulations using a realistic indoor environment model. We compare the performance of different relay configurations under variable obstacle densities. We show that a typical 60GHz indoor network should employ either a multi-relay configuration or a single-relay configuration with a smart relay selection mechanism to achieve acceptable outage rates. In the use of multiple-relay configuration, both analytical and simulation studies indicate that increasing the number of cooperative relays does not improve the system performance significantly after a certain threshold.

Collaborative and Cognitive Network Platforms: Vision and Research Challenges Onur, Ertan; Hawas, Mohamed Gamal; de Groot, Sonia Marcela Heemstra; Niemegeers, Ignas G. M. M. (Springer Science and Business Media LLC, 2011-05-01) In this paper, we present a visionary concept referred to as Collaborative and Cognitive Network Platforms (CCNPs) as a future-proof solution for creating a dependable, self-organizing and self-managing communication substrate for effective ICT solutions to societal problems. CCNP creates a cooperative communication platform to support critical services across a range of business sectors. CCNP is based on the personal network (PN) technology which is an inherently cooperative environment prototyped in the D...
An Investigation of Link Quality Assessment for Mobile Multi-hop and Multi-rate Wireless Networks Zhou, Jinglong; Jacobsson, Martin; Onur, Ertan; Niemegeers, Ignas (Springer Science and Business Media LLC, 2012-07-01) Wireless ad hoc networks will be an important component in future communication systems. The performance of wireless ad hoc networks can be improved by link quality-aware applications. Wireless link quality is dynamic in nature, especially in mobile scenarios. Therefore, accurate and fast packet delivery ratio estimation is a prerequisite to good performance in mobile, multi-hop and multi-rate wireless ad hoc networks. In this paper, we propose a novel packet delivery ratio estimation method that improves t...
Cooperative diversity in carrier frequency offset Yılmaz, Ali Özgür (Institute of Electrical and Electronics Engineers (IEEE), 2007-04-01) Cooperative diversity can enjoy the same benefits of MIMO systems when there is no possibility of carrying multiple antennas on a communication terminal. The main distinction between MIMO and cooperative diversity systems is the inherent asynchronism in the latter. We propose a model to study the effects of carrier frequency offset along with symbol asynchronism. Based on the proposed model, a Viterbi equalizer is utilized as a solution for demodulation. Through simulations, it is observed that such a solut...
WAKE-UP RECEIVERS FOR WIRELESS SENSOR NETWORKS: BENEFITS AND CHALLENGES Demirkol, Ilker; Ersoy, Cem; Onur, Ertan (Institute of Electrical and Electronics Engineers (IEEE), 2009-08-01) For successful data delivery, the destination nodes should be listening to the medium to receive data when the sender node starts data communication. To achieve this synchronization, there are different rendezvous schemes, among which the most energy-efficient is utilizing wake-up receivers. Current hardware technologies of wake-up receivers enable us to evaluate them as a promising solution for wireless sensor networks. In this article the benefits achieved with wake-up receivers are investigated along wit...
Analysis of target detection probability in randomly deployed sensor networks Onur, Ertan; Delic, Hakan (Institute of Electrical and Electronics Engineers (IEEE), 2007-10-01) The main functionality of a surveillance wireless sensor network is to detect unauthorized traversals in a field. In this paper, we develop a formulation to determine the probability of detecting a randomly positioned target by a set of binary sensors to serve as the deployment quality measure. This formulation leads to a recipe to determine the number of sensors required to deliver a certain deployment quality level. The sensing- and communication-neighbor degrees which can be used as design criteria in a ...
