Abstract: Body sensor network offers a real-time remote monitoring of patients with minimum cost to the health care system. It gathers health parameters by wireless nodes attached on the body or implanted inside the body and relay the information to a medical application. The power source in BSN like any other mobile system is the major concern. The power source recharge is very difficult and inconvenient in most cases. Energy saving is critical to prolong the network lifetime. This work targets the expansion of network lifetime with a context-aware dynamic transmission scheme. Our proposed scheme reduces data transmission by a status awareness definition. We used another energy saving scheme called burst communications to compare methods. Burst communication reduces MAC overhead by a less number of headers for the same data. The simulation results show up to 90 percent reduction in transmission energy especially in high traffic generator nodes.
