Applications Oriented Medium Access Control Protocols For Wireless Sensor Networks

In this article two new MAC protocols for wireless sensor networks based on TDMA (Time Division Multiple Access) access method are proposed. The proposed protocols are convenient for applications demanding a small number of sensors highly concentrated in a small region, such as in medical areas. The main characteristic of the proposed protocols is the simplified access scheduling that guarantees a low energy consumption and a reduced overhead. The energy consumption of the proposed protocols are estimated analytically and compared to the consumption of the protocols known in the literature. Also a simplified analysis of messages transference delay of proposed protocols is calculated. The results show that the energy consumption of the proposed protocols, in certain conditions, are smaller than other compared protocols. messages transference delay are relatively small and proposed protocols are more adjusted for transference of messages simultaneous.75586593Ye, W., Heidemann, J., Estrin, D., An energy-efficient MAC protocol for wireless sensor networks (2002) Proceedings of the IEEE International Conference on Computer Communication, pp. 1567-1576. , USC/Information Sciences Institute, New York, USAVan Dam, T., Langendoen, K., An adaptive energy-efficient MAC protocol for wireless sensor networks (2003) Proceedings of the First International Conference on Embedded Networked Sensor Systems, pp. 171-180. , ACM PressPolastre, J., Hill, J., Culler, D., Versatile low power media accesss for wireless sensor networks (2004) Proceedings of the 2 Nd International Conference on Embedded Networked Sensor Systems, pp. 95-107. , ACM PressKalidindi, R., Ray, L., Kannan, R., Iyengar, S., Distributed Energy Aware MAC Layer for wireless sensor networks International Conference on Wireless Networks, Las Vegas, Nevada, 2003Ranjendran, V., Obraczka, K., Garcia-Luna-Aceves, J.J., Energy-efficient collision-free medium access control for wireless sensor networks (2003) Proceedings of the First International Conference on Embedded Networked Sensor Systems, pp. 181-192. , ACM PressOliveira, S.S., Motoyama, S., Proposal of na MAC protocol for wireless sensor network with fixed scheduling of channels (2007) Proceedings of the International Workshop on Telecommunications - IWT/07, pp. 178-182. , Minas Gerais, Brasil, INATELYe, W., Heidemann, J., Estrin, D., Medium Access Control with Coordinated Adaptive Sleeping for Wireless Sensor Networks (2004) IEEE/ACM Trans.
