This paper presents MyMANET, a kernel module that provides a framework for ad hoc communication using commodity hardware. It exposes network measurements and provides an interface for inserting a routing protocol. MyMANET is based on a Layer 2.5 approach, which one calls the Wireless Decision Layer (WDL). Such a system seems suitable for developing regions with infrastructure constraints, where lab-developed solutions often do not work in practice. It models wireless connectivity without maintaining any explicit representation of topology. These features make it suitable for networks with transient topologies or bursty traffic. Here the author describes the challenges, design goals and architecture of the system, with a focus on an extreme case of transient topology, namely Mobile Ad hoc Networks (MANETs).
