Beaconless Geo-Routing Under The Spotlight: Practical Link Models and Application Scenarios
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 the developed framework. For a better perspective,
the two protocols are actually compared to a hypothetical limit
case; one which offers optimal energy and latency performance.
Finally, we present four different application scenarios. For each
scenario, we highlight the geo-routing protocol which performs
the best and discuss the reasons behind it.
