The invention relates to a method of monitoring a plurality of vital parameters of a patient 10 using a body sensor network with a set of on-body sensors 1 and at least one off-body monitoring device 2, the method comprising the following steps: with each on-body sensor 1, sensing a vital parameter and transmitting data related to the sensed vital parameter to the off-body monitoring device 2, and for at least one of the on-body sensors 1, determining the inclination of this on-body sensor 1 relative to the off-body monitoring device 2. In this way, a reliable and easy to use possibility for monitoring vital parameters of a patient 10 using a body sensor network is provided that minimizes the performance problem produced by RF attenuation caused by the body of the patient 10.
