Efficient heterogeneous communication range management for dynamic WBAN topology routing

WBAN should be robust against frequent changes in the network topology; The data mostly consists of medical information. Hence, high reliability and low delay is required; Dynamic communication range management is proposed based multi-commodity flow model which allows to prevent sensor node saturation and take best action against reliability and the path loss, by imposing an equilibrium use of sensors during the routing process. Experimental results show that our proposition balances the energy consumption of nodes effectively and maximize the network lifetime. It will meet the enhanced WBAN requirements, including better energy management and less reliable routing overhead.
