This study presents models for management of voice and data traffic and new algorithms, which use call admission control as well as buffer management to optimise the performance of single channel systems such as wireless local area networks in the presence of mobile stations. Unlike existing studies, the new approach queues incoming voice packets as well as data packets, and uses a new pre-emption algorithm in order to keep the response time of voice requests at certain levels while the blocking of data requests is minimised. A new performance metric is introduced to provide uncorrelated handling of integrated services. Queueing related issues such as overall queue capacity, individual capacities for voice and data requests, the probability of blocking, and effects of waiting time on overall quality of service are considered in detail. Analytical models are presented and the results obtained from the analytical models were validated using discrete event simulations.

Path planning and localization for mobile anchor based wireless sensor networks Erdemir, Ecenaz; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2017) In wireless sensor networks, sensors with limited resources are distributed in a wide area. Localizing the sensors is an important problem. Anchor nodes with known positions are used for sensor localization. A simple and efficient way of generating anchor nodes is to use mobile anchors which have built-in GPS units. In this thesis, a single mobile anchor is used to traverse the region of interest to communicate with the sensor nodes and identify their positions. Therefore planning the best trajectory for th...
Scheduling Policies for Minimizing Age of Information in Broadcast Wireless Networks Kadota, Igor; Sinha, Abhishek; Uysal, Elif; Singh, Rahul; Modiano, Eytan (2018-12-01) In this paper, we consider a wireless broadcast network with a base station sending time-sensitive information to a number of clients through unreliable channels. The Age of Information (AoI), namely the amount of time that elapsed since the most recently delivered packet was generated, captures the freshness of the information. We formulate a discrete-time decision problem to find a transmission scheduling policy that minimizes the expected weighted sum AoI of the clients in the network. We first show that...
SWIM : a new multicast routing algorithm for wireless networks Akyürek, Alper Sinan; Uysal Bıyıkoğlu, Elif; Department of Electrical and Electronics Engineering (2011) In this work, a new multicast routing algorithm for wireless networks is presented. The algorithm, called SWIM (Source-initiated WIreless Multicast), is a depth-optimal multicast tree formation algorithm. SWIM is fully distributed and has an average computational complexity of O(N 2 ). SWIM forms a shared tree from the source(s) to destinations; yet, as a by-product, it creates a multicast mesh structure by maintaining alternative paths at every tree node. This makes SWIM suitable for both ad hoc networks a...
Evaluation of Terahertz Channel in Data Centers MOLLAHASANİ, Shahram; Onur, Ertan (2016-04-29) Designing data center network topologies with the objective of minimizing cost, increasing bisection bandwidth and decreasing latency is a difficult problem. The solutions in the literature mainly concentrate on wired networks and minimizing wiring costs thereof. Only a few proposals address the benefit of employing wireless communications in data centers due to spectrum and bandwidth limitations of current wireless communication technologies. By using terahertz communication in a data center as a complemen...
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...
