Contention Resolution with Heterogeneous Job Sizes [PDF]
, 2006 We study the problem of contention resolution for different-sized jobs on a simple channel. When a job makes a run attempt, it learns only whether the attempt succeeded or failed. We first analyze binary exponential backoff, and show that it achieves a makespan of V2Θ(√logn) with high probability, where V is the total work of all n contending jobs ...

Joint estimation and contention-resolution protocol for wireless random access
, 2013 We propose a contention-based random-access protocol, designed for wireless networks where the number of users is not a priori known. The protocol operates in rounds divided into equal-duration slots, performing at the same time estimation of the number ...

Quo Vadis Banking Union? Discussions over the Resolution of Banks
Acta Universitatis Lodziensis. Folia Oeconomica, 2018 Transferring the right to make the decision concerning a bank’s resolution onto the international level has long been the bone of contention between the European Union’s Member States.

Contention Resolution, with and without a Global Clock
Proceedings of the 58th Annual ACM Symposium on Theory of ComputingIn the Contention Resolution problem $n$ parties each wish to have exclusive use of a shared resource for one unit of time. The problem has been studied since the early 1970s, under a variety of assumptions on feedback given to the parties, how the parties wake up, knowledge of $n$, and so on.

Strategic Contention Resolution in Multiple Channels [PDF]
, 2018 We consider the problem of resolving contention in communication networks with selfish users. In a \textit{contention game} each of $n \geq 2$ identical players has a single information packet that she wants to transmit using one of $k \geq 1$ multiple-access channels.

Enhancing the Selection of Backoff Interval Using Fuzzy Logic over Wireless Ad Hoc Networks
The Scientific World Journal, 2015 IEEE 802.11 is the de facto standard for medium access over wireless ad hoc network. The collision avoidance mechanism (i.e., random binary exponential backoff—BEB) of IEEE 802.11 DCF (distributed coordination function) is inefficient and unfair ...

Probabilistic Model Checking: One Step Forward in Wireless Sensor Networks Simulation
International Journal of Distributed Sensor Networks, 2015 A novel collision resolution algorithm for wireless sensor networks is formally analysed via probabilistic model checking. The algorithm called 2CS-WSN is specifically designed to be used during the contention phase of IEEE 802.15.4. Discrete time Markov
