Design of Coded ALOHA With ZigZag Decoder
IEEE Access, 2019 In this study, we investigated the effects of combining a zigzag decoder (ZD) with a coded ALOHA using the successive interference cancellation (SIC) technique to retrieve packets from collisions.

Maximum throughput analysis and enhancement of slotted ALOHA for multihop ad hoc networks [PDF]
, 2004 In this paper, we analyze the maximum throughputs of slotted-ALOHA-based multihop ad hoc networks with and without capture, by considering the degree (number of neighbors) of each node, and, different from prior research, allowing each node to have a ...

A Request-Transmission Splitting Scheme for V2X Networks: Design and Throughput Analysis
IEEE Access, 2019 In the existing slotted ALOHA-based access schemes for vehicle-to-everything (V2X) networks, the duration of a time interval for competitive users contains the whole process of requesting and transmission. To improve the access capacity for V2X networks,

Energy efficiency considerations in software‐defined wireless body area networks
Engineering Reports, Volume 6, Issue 3, March 2024.Integrating software‐defined networking into wireless body area network presents several challenges in terms of safe data exchange, architectural framework, and resource efficiency. Because energy expenses account for a considerable portion of network expenditures, energy efficiency has to turn out to be a crucial design criterion for modern networking

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

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 ...

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 ...
