Description
Summary:The proposed scheme maximizes the communication rates of multiple sender sensors to a terminal sensor while assuring a given connection time without connection abortion caused by the depletion of available battery energy. Each wireless sensor chooses one of two radio transmission ranges with disparate energy consumptions when sending a packet. The proposed scheme generates an edge-capacity graph from a sensor network and finds the routing paths by applying an advanced version of the existing maximum-flow algorithm to the graph. Finally the scheme determines the transmission rate of packets from each sender node to the terminal node, which is the number of transmittable packets in the found routing paths divided by the given connection time.
