On physically secure and stable slotted ALOHA system [PDF]
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009 In this paper, we consider the standard discrete-time slotted ALOHA with a finite number of terminals with infinite size buffers. In our study, we jointly consider the stability of this system together with the physical layer security. We conduct our studies on both dominant and original systems, where in a dominant system each terminal always has a ...

LoRaSync: Energy efficient synchronization for scalable LoRaWAN
Transactions on Emerging Telecommunications Technologies, Volume 35, Issue 2, February 2024.LoRaSync is an energy‐efficient synchronization mechanism designed to support the implementation of slotted medium access control protocols for LoRa networks. Its robust design is based on real clock drift measurements, and a synchronization beacon skipping strategy is used in order to save power on the end‐devices Abstract Low‐power wide‐area networks

Modeling Slotted Aloha as a Stochastic Game with Random Discrete Power Selection Algorithms
Journal of Computer Systems, Networks, and Communications, 2009 We consider the uplink case of a cellular system where 𝑚 bufferless mobiles transmit over a common channel to a base station, using the slotted aloha medium access protocol.

Handshake mechanism selection in MANETs with directional antennas: A new evaluation view
Electronics Letters, Volume 60, Issue 4, February 2024.This letter theoretically derives the upper and lower bounds of neighbour discovery time of the network for both 1‐way and 2‐way. In order to better select the appropriate handshaking mechanism, a new evaluation parameter, the expected time for a node to complete mutual discovery with its neighbours, is proposed, which is shown to be approximately ...

On the optimal configuration of framed slotted ALOHA [PDF]
EURASIP Journal on Wireless Communications and Networking, 2016 The primary task of RFID readers is to identify multiple objects as quickly and reliably as possible with minimal power consumption and computation. One issue addressed in this study is the manner in which RFID systems adopting the framed slotted ALOHA (FSA) protocol should be configured so that the minimum identification delay can be achieved with a ...

Energy Efficient Uplink MAC Protocol for M2M Devices
IEEE Access, 2019 To enable connectivity between a massive number of devices on the Internet of Things (IoT) paradigm, machine-to-machine (M2M) communication is implied. The key feature of emerging and ad hoc networks, such as M2M communication, is a low-complexity medium
