Functionality δ Provides SansGrid abstraction δ Handles wireless communication δ Dynamically adapts to either router or sensor modes

The goal of the SansGrid project is to create a wireless infrastructure in which wireless sensors are able to seamlessly connect and transmit and/or receive data. SansGrid is, therefore, primarily a protocol which defines connection, authentication, data transfer, and sensor interaction by way of dynamically defined triggers. The aim of the SansGrid protocol is to be as radio agnostic and sensor independent as possible. The goal of the SansGrid capstone is to demonstrate a working implementation of the SansGrid protocol.
