Abstract
In Quality-of-service (QoS) aware routing for IEEE 802.15.4 Networks we address certain issues in delay and reliability domains. To overcome these issues, we propose to develop a routing protocol designed in the cluster tree network which consists of few modules like reliability module, packet classifier, hello protocol module and routing service module. The data is transferred from MAC layer to network layer in reliability module which takes care of transmission of messages and acknowledgements. Using the Packet classifier the packets are classified into the data and hello packets. The data packets are classified based on the priority. Hello protocol module construct neighbor table and maintain information about neighbor nodes reliabilities. Next using the routing service module routing table is built. The delay in the route is controlled using delay metrics, which is a sum of queuing delay and transmission delay.
