چکیده    Wireless body area networks consist of several devices placed on the human body, sensing vital signs and providing remote recognition of health disorders. low power consumption is crucial in these networks. a new energy-efficient topology is provided in this paper, considering relay and sensor nodes’ energy consumption and network maintenance costs. in this topology design, relay nodes, placed on the cloth, are used to help the sensor nodes forwarding data to the sink. relay nodes’ situation is determined such that the relay nodes’ energy consumption merges the uniform distribution. simulation results show that the proposed method increases the lifetime of the network with nearly uniform distribution of the relay nodes’ energy consumption. furthermore, this technique simultaneously reduces network maintenance costs and continuous replacements of the designer clothing. the proposed method also determines the way by which the network traffic is split and multipath routed to the sink.
