PicoRadio is a sensor network project in the Berkeley Wireless Research Center (BWRC) to develop low-cost meso-scale ubiquitous transceiver nodes with minimal power dissipation. The nodes are capable of self-organizing into an ad hoc wireless network without global synchronization. Each node in the network has the same protocol stack, which consists of a physical layer, a data link layer, a network layer and an application layer. This report summarizes the modeling and simulation of the data link layer using a development tool called VCC. VCC is a design platform allowing you to integrate intellectual property models to simulate, evaluate and select virtual components for various applications. In the VCC environment, the behavior of the data link layer protocol is captured and simulated, and the hardware/software architectural design space is explored by performance analyses.
