説明

In wireless ad-hoc networks, messages have to be energy-efficiently delivered to destination nodes by exchanging the messages among neighboring nodes. In our previous studies, the reactive type EAO and IEAO protocols are proposed to unicast messages. The electric energy consumption of a node p_i in the EAO and IEAO protocols is defined as the square of the distance between a pair of nodes p_i and p_j. In the EAO protocol, the total electric energy of nodes and delay time from a source node to a destination node can be reduced compared with the AODV protocol, but a source-to-destination route may not be found if the communication range of each node is shorter. We proposed the IEAO protocol to overcome this difficulty. However, each node in reality spends electric energy to perform a process, not communication device to send messages. Hence, it is necessary to reduce the number of transmissions of each node in a source-to-destination route. In this paper, we newly propose an REO (Reliable and Energy-Efficient One-to-one routing) protocol to reduce the number of transmissions of each node. In the REO protocol, for each node, a neighboring node to which the node can deliver a message with low message loss ratio and which has an uncovered neighbor node is selected as a prior node. In the protocol, if a node fails to deliver a message, the node retransmits the message. This means, the higher message loss ratio, the more number of retransmissions, i.e. the more electric energy is consumed. In the evaluation, we show the number of transmissions of each node in a source-to-destination route can be reduced in the REO protocol compared with other protocols.
