A Testbed for Data Routing in Low-Power WSNs using DV-Hop Based Trajectory Encoding Algorithm
Xiaofei Cao, Sanjay Madria · 2019
Trajectory-based routing is a common data forwarding protocol while collecting sensor data during a disaster or in a battlefield for situation-awareness. However, wireless sensor networks (WSNs) have limitations in available bandwidth and energy. The trajectory-based routing protocols could reduce redundant broadcasting to save energy and bandwidth significantly. In this demo, we will demonstrate the working of a DV-Hop (Distance Vector Hop) based trajectory encoding algorithm using virtual coordinates rather than using GPS data. Using the proposed trajectory based routing protocol, we achieve energy savings, reduced latency, reliability, better coverage, while routing data from a source node to a mobile sink.
