| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Light-Weight energy efficiency Media Access Control (LWMAC) is an asynchronous duty cycle MAC protocol to shorten the preamble length by selecting the node which is changed to be in active mode first during the preamble as a next hop node without selecting it in advance, and then reduces energy consumption in wireless sensor networks. However, LWMAC may increase the number of hops because it doesn't consider the distance from a source node to a next hop node. Therefore, when a source node selects a node which is far to a sink node as a next hop node, energy consumption cannot be reduced. In this paper, we propose a duty cycle MAC protocol that decreases the number of hops and reduces energy consumption by selecting a node that is closer to a sink node as a next hop node when more than two candidate nodes change to be in active mode until the end of preamble whose length is same in LWMAC. By the simulation, we evaluate the average number of hops of LWMAC and the proposed scheme. The simulation results show that the proposed scheme reduces the energy consumption by decreasing the average number of hops. |
