Understanding Interoperability in Internet of Things (IoT) Ecosystem

Abstract

IoT is a collection of interrelated computing devices. IoT is  the  uniquely  addressable  using  IPv6  protocol, which  enables  these  objects  to  collect  and  exchange  data  based  on  standard  communication  protocols.  The  IoT  market  is  expected  to  grow  steadily  as  billions  of  devices,  services  and  systems  become  connected,  it  is  fragmented  due  to  the  extreme  degree  of  heterogeneity  in  terms  of  devices, protocols,  controllers,  network  connectivity  methods,  application  protocols,  standards,  data  formats so on. Interoperability  is  the  main  obstacle  towards  the  promotion  of  IoT  adoption  and  innovation. As  a  number  of  components  increases,  there  is  a  huge  demand  for  robust  architecture  and  infrastructure  with  fewer  issues  in  terms  of  connectivity,  security,  privacy,  traffic  of  data  and  interoperability. In order to mitigate this weakness, here we present and describe intimately a comparative study of various existing IoT interoperability architectures consistent with protocols and technologies used also as their advantages, limitations and solutions.
