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 the accuracy and responsiveness of the packet delivery ratio estimation. The proposed link quality estimation components are implemented in a IEEE 802.11b/g test-bed. The experiment results show that the accuracy of the packet delivery ratio estimation can improve up to 50% in mobile scenarios without introducing overhead. We also show the end-to-end performance impact of this improved estimation on route selection using different routing metrics and configurations. The measurement results show that our packet delivery ratio method leads to better route selection in the form of increased end-to-end throughput compared to traditional methods, which respond slowly to the link dynamics.

Cooperative Communications in Future Home Networks Genc, Zulkuf; Rizvi, Umar H.; Onur, Ertan; Niemegeers, Ignas (Springer Science and Business Media LLC, 2010-05-01) 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, ...
The performance and efficiency of envelope elimination and restoration transmitters for future multiple-input multiple-output wireless local area networks Nesimoglu, T.; Parker, S. C. J.; Morris, K. A.; McGeehan, J. P. (Institution of Engineering and Technology (IET), 2008-03-01) The inefficiency of contemporary power amplifiers ( PAs), when operating in their linear region, is a major obstacle to mobile operation of wireless local area networks ( WLANs) based on IEEE 802.11n. Therefore the use of more efficient envelope elimination and restoration ( EER) transmitter architectures is considered. In addition to high efficiency it is also necessary to satisfy the spectral mask and achieve satisfactory link- level performance. Link- level simulations of a contemporary WLAN PA show that...
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 ...
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...
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...
