Ad hoc 네트워크에서 전력인지 QoS 라우팅 프로토콜

Abstract

In the ad hoc networks, the limitation on the availability of power for operation is a significant bottleneck, given the requirements of portability, weight, and size of mobile devices. Hence, the use of routing metrics that consider the capabilities of the power sources of the network nodes contributes to the efficient utilization of energy. This paper presents a QoS routing protocol that minimize the power consumed by a packet in traversing from source node to the destination node. Results obtained of simulation show that, with our approach we can reduce the power consumption of nodes and increases the life time of the network. Power aware routing protocol of MANET(Mobile Ad hoc Network) minimized the power consumption of each node and helped to extend the duration of the network. But due to the nature of the protocol, it tends to increase the delay transmission, so multimedia transmissions were difficult to apply. In this paper, power aware routing protocol is proposed considering the delay transmission that can be applied to Ad hoc network. The proposed protocol consider two conflicting index, delay transmission and power consumption at the same time, maintaining a certain level of delay transmission while minimizes the power consumption. In Simulation, we compared to not-considering delay transmission are, delay transmission significantly decreased by 30% while the power consumption less than 10% increased.
