An efficient routing protocol can make heterogeneous WSN better to provide a reliable and energy efficient connectivity between nodes and the sink. When designing a routing protocol for heterogeneous. For efficient switching clock rate and to increase network robustness the system introduces 802.11 standard protocols. A C-MAC is introduced; it may be a feasible approach to prolong the network lifetime, yet maintaining the network connectivity. CMAC first uses any cast to wake up forwarding nodes, and then converges gradually from route-suboptimal any cast with unsynchronized duty cycling to route-optimal unicast with synchronized scheduling.
