Sleep control considering relay node information in mobile Ad-hoc networks

In mobile ad-hoc networks (MANET), the suppression of energy consumption is very important, because the networks may be used in situations with disaster or lacking of infrastructures. In our study, we propose a sleep control method exploiting a routing protocol using mobile agent, where nodes not included in a derived route go to sleep. In the proposed method, a node sends a sleep control packet before a packet transmission. The node which received the packet decides to sleep or not autonomously. From performance evaluation by computer simulation, we show that the proposed method can decrease the energy consumption while maintaining the packet delivery rate.
