Instead of being measured face to face, ehealthcare is a new promising technology that facilitates monitoring patients health related parameter continuously and in real time, with the help of wireless sensor network. Wireless Body Sensor Network (WBSN) reduces heavy dependence on specialized healthcare staff and thus a desirable technique for countries that lack sufficient medical infrastructure and trained staff. However, layout and design of wireless body sensor network without security can influence the system. In this paper we review existing WBSNs and introducing a new approach for Proxy Patient Server (PPS) and a Proxy doctor Server (PDS) to improve ehealthcare services.

Now days, energy consumption in conniving of mobile wireless network is very important research topic due to its pervasive ingress and large potential consumption. For that reason, effective solutions are needed for the green wireless networks i.e. power cutback wireless network because of its obligatory drift. In this paper, the foremost abridge the grade worn in the citations for concert conduct. After that, accent on recounting the approach anticipated by exposition a good quality of reference from documentation. The chief investigate administration are : the innate rank research, where the attempt are principally centralized on the supremacy loudspeaker segment; the unit blueprint alteration together with the cell-breathing performance and exposure add-on methods like femto cells and relay; in totting up, also encompass the walkie-talkie store supervision and the cognitive walkie-talkie . These tactic are scrutinize, equate, open and next a shell of sorting and combination is planned. At last, narration a few coopetition projects committed for this area.
