Network operators are looking toward LTE License Assisted Access (LAA) as a means of extending capacity by offloading traffic to unlicensed bands. However, operation in these bands requires abiding certain coexistence rules terms channel access. The description the existing literature is not always line with latest standards. Therefore, this article, we clarify LAA, focusing on access and metho...

We consider the distributed channel access problem for a system consisting of multiple control subsystems that close their loop over shared wireless network. propose method providing deterministic without requiring explicit information exchange between subsystems. This is achieved by utilizing timers prioritizing with respect to local cost which we derive transforming objective form allows its ...

The physical transport methods used in wireless communication differ from wired communication. These differences affect how a secure channel can be established in a wireless environment. The purpose of this tutorial is to provide an overview of how a secure channel is set up in a wireless environment that uses the 802.11 or WAP standards.

The spectrum sensing and channel access is a classic exploration vs. exploitation problem for cognitive radio overlay networks, where the secondary users access the idle portion of licensed primary users. We propose a simple architecture to separate the spectrum sensing form the channel access so that optimal sensing can be achieved.
