MAC based Routing in IOT

The purpose of this paper is to explain why the physical layer is important regarding the Internet Of Things, and show various routing metrics that were previously used. We first are explained how and why the MAC layer must interact with the routing metrics that we use. A complex and comprehensive analysis of these metrics is the done and then their performance comparison is executed. The better performing metric is found out and then a new Q metric is introduced which supersedes the performance quality of the previous metrics.
