دانلود ESR: Energy aware and Stable Routing protocol for WBAN network

Abstract

Wireless  body  area  network  (WBAN)  calls  for  a next  generation  in  wireless  networks.  This  new  generation  is  designed to operate autonomously, to connect various medical sensors  and  appliances  located  on  or  inside  a  human  body. Mobile WBANs have been designed, offering numerous practical and innovative services so that health care and quality  of  life  can  be  improved.  Thus,  the  equipment  used  in WBAN is usually mobile and autonomous which imposes high constraint  on  energy.  That  is,  the  energy  efficiency  must  be taken  into  account  as  one  of  the  objectives  of  the  routing  protocol  designed  for  this  type  of  network.  Although  mobile nodes  may  cause  link  breaks,  most  of  studies  ignore  the  link stability.  In  this  paper,  we  propose  a  stable,  reliable,  energy  efficient routing protocol for mobile Wireless Body Area Networks.  It  preserves  the  residual  energy  of  nodes  with  an  increase  network  lifetime.  To  achieve  this  goal,  we  use  an objective  model  to  select  energy-efficient  paths  with  stable links. Simulation results demonstrate that our protocol improves  the  state  of  the  art  in  terms  of  energy  consumption and routing overhead.
