| dc.description.abstract | Delay Tolerant Network (DTN) is emerging as a solution for supporting data transfer in intermittently connected networks. In DTN, to cope with long disconnections, messages are buffered for a long period of time. Thus, according to the queue management the performance can be affected significantly. Power is also a scarce resource in DTN. Energy can be saved by putting mobile nodes into sleep during long delayed connections. In this thesis, a Medium Access Control (MAC) protocol that supports adaptive sleep scheduling of a mobile node is proposed. Based on the MAC layer operation, an adaptive power management framework is developed. The framework considers power saving and buffer management together in order to minimize power consumption while minimizing the performance degradation of buffer management for the mobile node. Variations of the performance of a traffic source node which are affected by diverse network parameters are also investigated. | en_US |
