Least Path Interference Beaconing Protocol (LIBP): A Frugal Routing Protocol for The Internet-of-Things
This paper presents a frugal protocol for sensor readings dissemination in the Internet-of-Things (IoT). The protocol called Least Path Interference Beaconing (LIBP) is based on a lightweight path selection model that builds a routing spanning tree rooted at the sink node based on information disseminated through a periodic beaconing process. LIBPs frugality results from a routing process where the sensor nodes select the least path interfering parents on the routing spanning tree with the expectation of flow balancing the traffic routed from nodes to the sink of a sensor network. The simulation results produced by Cooja under the Contiki operating system are in agreement with previous results obtained under the TinyOS operating system. They reveal that LIBP outperforms different versions of the RPL protocol and the CTP protocol in terms of power consumption, scalability, throughput and recovery from failure as well as its frugality as a routing protocol.
