Technological advances in microelectronic and telecommunication fields enable the existence of tiny computing units, very small and more efficient. In the context of these new technologies, Wireless Sensor Networks (WSN) have emerged. The main research objective in WSN domain is the development of algorithms and protocols ensuring minimal energy consumption. In this paper, we propose on energy efficient token based MAC protocol integrated with sleep scheduling for WSNs, in order to reduce energy consumption of each sensor node which is one of the important issues to prolong the network lifetime. To derogate energy consumption most of the MAC protocols in WSN exploits low duty-cycle; among those RMAC, HEMAC allows a node to transmit data packet for multi-hop in a single duty-cycle. To reduce energy consumption on prolonged network life time sensor networks are usually duty cycled; each node remains in low power sleep mode most of the time and wakes up periodically to sense for channel activities. In the above said MAC protocols, due to the synchronized scheduling and transmission collisions, flooding increases resulting in energy waste and low throughput. Allowing for nodes to operate with a new sleep based token approach; we intend to produce energy efficiency in an event based approach by cutting down flooding, collision and traffic congestion. Simulation studies of the proposed MAC protocol have been carried out using Castalia simulator. [ABSTRACT FROM AUTHOR] |
