Routing for Wireless Mesh Networks with Multiple Constraints Using Fuzzy Logic

 ,
 Since  wireless  mesh  networks  are  ad-hoc  in  nature,  many  routing  protocols  used  for  ad-hoc  networks  lik e  AODV  are also used for  wireless mesh networks by conside ring only the shortest route to destination. Since data transfer in  wireless  mesh networks is to and from the AP, these protocol s lead to congested routes and overloaded APs. To r educe congestion, the  routing  protocols  such  as  traffic  balancing  which  c hoose  routes  based  on  medium  usage  of  the  route  wer e  used.  However,  routing  is  a  multi  constraint  problem.  To  make  rout ing  decisions  based  on  more  than  one  constraint  viz .,  buffer  occupancy,  node  energy  and  hop  count  and  to  provide  an  efficie nt  routing  method  for  wireless  mesh  networks,  a  fuzzy  multi -  constraint  AODV  routing  is  proposed  in  this  paper.  Simulation  results  in  ns-2  verify  that  they  perform  better  than  single  constraint  routing.
