In this paper, we examine the question of how effective routing is for reliably and efficiently delivering data in a wireless network. With the emergence of the Internet of Things, there is a renewed focus on multi-hop wireless networking to connect these systems of smart-devices. Many of the proposals to support this new networking paradigm continue to use the concept of routing a path between users is formed via a series of point-to-point links. We believe that the characteristics of the wireless environment inherently make link-based routing unsuitable for wireless networking, and that new approaches need to be considered. In this paper, we demonstrate that link-based routing 1 experiences high packet loss due to the inherently unreliable nature of control information, 2 is unable to ensure reliable message delivery in a lossy environment, and 3 incurs a high cost for route maintenance and repair.
