We consider a wireless broadcast network with a base station sending time-sensitive information to a number of clients. 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 scheduling policy that minimizes the expected weighted sum AoI of the clients in the network. To the best of our knowledge, this is the first work to provide a scheduling policy that optimizes AoI in a wireless network with unreliable channels.

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...
Dynamic radio channel management in cellular mobile communication systems
Yilmaz, N; Ergul, R (2004-09-29)
We present a dynamic radio bandwidth management scheme for mobile communication systems to achieve a high level of QoS for both handoff calls and new calls, while at the same time to improve the utilization of wireless network resources. The simultaneous satisfaction of these two actually conflicting interests will be thanks to two major key features. First, due to the apriori information about handoff reservation requests that is provided by the mobile terminal. This information is based on the cell transi...
Increasing energy efficiency of rule-based fuzzy clustering algorithms using CLONALG-M for wireless sensor networks
Sert, Seyyit Alper; Yazıcı, Adnan (2021-09-01)
Because of its efficiency, clustering is used for effective communication in Wireless Sensor Networks (WSNs). In the WSN clustering area, fuzzy approaches are found to be superior to crisp cluster counterparts when the boundaries between clusters are unclear. As a result, many studies have proposed some fuzzy-based solutions to the cluster problem in WSNs. Most rule-based fuzzy clustering systems employ field experts in trial and error processes, identifying and defining fuzzy rules as well as the forms of ...
A new scalable service discipline for real-time traffic: The framed-deadline scheduler
Schmidt, Şenan Ece (Elsevier BV, 2007-03-26)
Qulaity of Service (Qos) support in a scalable and low-complexity fashion is important in high-speed networks carrying real-time traffic. There are service disciplines that can provide end-to-end bandwidth and delay guarantees. However, they are designed to operate with expensive output quenching switches or with combined input-output queuing (CIOQ) switches that require very complicated fabric work with a CIOQ packet switch to provide the same end-to-end QoS guarantees as service disciplines that only work...
Design of dual-frequency probe-fed microstrip antennas with genetic optimization algorithm
Ozgun, O; Mutlu, S; Aksun, MI; Alatan, Lale (2003-08-01)
Dual-frequency operation of antennas has become a necessity for many applications in recent wireless communication systems, such as GPS, GSM services operating at two different frequency bands, and services of PCS and IMT-2000 applications. Although there are various techniques to achieve dual-band operation from various types of microstrip antennas, there is no efficient design tool that has been incorporated with a suitable optimization algorithm. In this paper, the cavity-model based simulation tool alon...
