| Popis: | The performance of CSMA MAC degrades significantly due to hidden terminal problem as carrier sensing cannot avoid collision, this problem is faced by many CSMA MAC based systems hence it is one of the important issue which needs tobe solved in wireless communications. Idle listening of sensor nodes is a major source of energy waste during reprogramming and must be minimized. Although CSMA MAC is in the TinyOS release & the majority reprogramming systems use CSMA, the proposed work replaces existing CSMA with more efficient MAC i.e. a T-MAC. It uses TMAC unlike CSMA MAC in Deluge & most of the dissemination protocols to make the protocol more energy efficient, proper coordination & time synchronization between the node, proper bandwidth utilization & to carry appropriate MAC layer management functions like periodic wake up and sleep, neighbor's knowledge etc. TMAC uses the simple policy with fixed frames with variable active period & time-out interval which add many benefits like decreasing idle listening by duty cycle, collisions etc. hence improving the performance of designed protocol, making it better than the other protocols as it is more capable & adaptive as T-MAC prevents the packet collisions & ultimately solves the hidden terminal problem. |
