Wireless Body Area Network (WBAN) is a technology, used for remote monitoring of patients where the wired network is not available. The sensed data is transmitted via internet to doctors so that they can aid the condition of a patient. Sensor nodes are being planted inside or outside the human body keeping in mind that there should be less number of nodes as well as radio model transmitting and receiving frequency should be less, so that it may not interfere with human body. In this work, a routing technique is proposed that will transfer critical data to base station immediately. The concept of mobility has also introduced. M-ATTEMPT protocol is used for comparison. Simulation result reveals that using single-hop approach is much better than using multi-hop approach in terms of network lifetime and packet transmission.
