We propose a simple yet effective wireless network coding (NC) and decoding technique. It utilizes spatial diversity through cooperation between nodes which carry out distributed encoding operations dictated by generator matrices of linear block codes. For this purpose, we make use of greedy codes over the binary field and show that desired diversity orders can be flexibly assigned to nodes in a multiple unicast network, contrary to the previous findings in the literature. Furthermore, we present the optimal detection rule for the given model that accounts for intermediate node errors and suggest a network decoder using the sum-product algorithm. The proposed sum-product detector exhibits near optimal performance.

Practical Methods for Wireless Network Coding With Multiple Unicast Transmissions Aktas, Tugcan; Yılmaz, Ali Özgür; AKTAŞ, EMRE (2013-03-01) We propose a simple yet effective wireless network coding and decoding technique for a multiple unicast network. It utilizes spatial diversity through cooperation between nodes which carry out distributed encoding operations dictated by generator matrices of linear block codes. In order to exemplify the technique, we make use of greedy codes over the binary field and show that the arbitrary diversity orders can be flexibly assigned to nodes. Furthermore, we present the optimal detection rule for the given m...
Wireless network coding for multiple unicast transmissions Aktaş, Tuğcan; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2014) In this work, firstly we propose a practical and effective cooperative communication technique based on network coding (NC) in order to mitigate the detrimental consequences of fading in wireless channels. We base our formulation on multiple unicast transmissions which is the natural way of communication in many modern wireless networks. The proposed technique utilizes spatial diversity through cooperation between overhearing nodes which carry out distributed encoding operations dictated by the generator ma...
Differential network coding in wireless networks Telsiz aǧlarda farksal aǧ kodlamasi Özdemir, Özgür; Yılmaz, Ali Özgür (2009-10-29) In this paper a three-terminal communication scenario where two users exchange information by employing differential binary modulation and network coding via a relay is considered. The transmission is divided into three slots in time where the first and second slots are allocated to the transmission of differential encoded data of the users. After demodulation, the relay broadcasts the bit-wise XOR-ed and differential encoded packet to the users in the third slot. The optimum detector and a simplified decis...
Cooperative Localization In One-Hop And Multi-Hop Wireless Sensor Networks Using Alternating Minimization Algorithm Erdemir, Ece Naz; Tuncer, Temel Engin (2016-05-19) In this work, a new approach is proposed to solve cooperative localization problems in wireless sensor networks for both one-hop and multi-hop cases. To find the unknown positions of randomly distributed sensors with limited power and communication ability, noisy inter-sensor distances and anchor node positions are used. In a plane, when the distances between a sensor and at least three neighbor anchors are known, it is possible to find the sensor position by solving a linear set of equations. However, for ...
Evaluation of priority dependent and time scheduled MAC layer protocols for ad-hoc networks Erdeğer, İsmail; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2015) Ad-hoc networks have very unique features, such as dynamic topologies, relatively limited bandwidth and wireless signal propagation schemes, which present various challenges for wireless communication. In this thesis, control mechanisms for channel access scheduling and topology in ad-hoc networks are evaluated, which utilize the information from two-hop neighborhood to cope with the communication difficulties in ad-hoc networks. Channel assignment is one of the most important topics for ad-hoc networks. Ch...
