Ahmed Bader, Karim Abed-Meraim, and Mohamed-Slim Alouini

TL;DR
This paper develops a realistic link model for beaconless geo-routing, accounting for differing communication ranges of control and data packets, and evaluates protocol performance across various practical scenarios.
Contribution
It introduces a practical link model and strategies to bridge control-data range gaps, enabling more accurate analysis of beaconless geo-routing protocols.
Findings
Developed a realistic communication range model based on packet length.
Compared protocols against an optimal hypothetical limit case.
Identified the best-performing protocol for each application scenario.
Abstract
Analysis and simulation of beaconless geo-routing protocols have been traditionally conducted assuming equal communication ranges for the data and control packets. In reality, this is not true since the communication range is actually function of the packet length. Control packets are typically much shorter than data packets. As a consequence, a substantial discrepancy exists in practice between their respective communication ranges. In this paper, we devise a practical link model for computing the effective communication range. We further introduce two simple strategies for bridging the gap between the control and data packet communication ranges. Our primary objective in this paper is to construct a realistic analytical framework describing the end-to-end performance of beaconless geo-routing protocols. Two flagship protocols are selected in this paper for further investigation under…
