UPS: Unified Protocol Stack for wireless sensor networks

The complexity of allowing different protocols to operate in concert in the same layer has generally been ignored in wireless sensor networks. In this paper, we propose a complete protocol stack framework called UPS (Unified Protocol Stack) as a solution for incorporating different protocols within WSNs through enabling the co-existence of multiple modules in same stack layer as well as providing unified access to cross-layer data. The system block diagram for UPS is shown in Fig. 1.
