A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

Adaptation for the retransmission in VoIP applications

Journal of Communications and Networks, 2017
An adaptive retransmission scheme can be used for voice over Internet protocol services to provide a certain level of quality of service. However, parameters used for adaptive retransmission must be selected carefully due to unintended frame loss in the channel and in the playout buffer.

Channel Constrained Multiple Selective Retransmissions for OFDM System: BER and Throughput Analysis

IEEE Access, 2019
Hybrid automatic repeat request (HARQ) retransmission is an effective method to combat time-variant channel fading. Conventional HARQ methods initiate retransmission of failed packet without exploiting channel knowledge.

DRDT: Distributed and Reliable Data Transmission with Cooperative Nodes for LossyWireless Sensor Networks

Sensors, 2010
Recent studies have shown that in realistic wireless sensor network environments links are extremely unreliable. To recover from corrupted packets, most routing schemes with an assumption of ideal radio environments use a retransmission mechanism, which ...

Delay Probability Distributions of Acknowledged CSMA/CA With Finite Re-Transmissions Over Fading Channels

IEEE Access
The delay distribution observed between the dll of a pair of neighbouring nodes in wireless mesh networks is studied. Specifically, we model the delay for unslotted csma with acknowledgments and multiple transmission retries under given channel access ...
