Analysis of clustered QoS routing protocol for distributed wireless sensor network

A wireless network is a collection of wireless nodes within decentralized and distributed network architecture. This distributed architecture gives rise to issues concerning resilience, node mobility, link failure, routing overhead and drop rate. To avoid these issues and satisfy QoS requirements, a new routing protocol known as clustered QoS routing protocol (CQRP) is proposed. This routing protocol creates a cluster with a grouping of nodes and assigns a cluster head. This cluster head is used to assign an available link for the wireless node to avoid issues with resilience and link failure. Cluster members communicate with data packets through the cluster head. Through the use of this cluster head, quality of service requirements for a distributed network can be met. Experimental results show that the performance of the proposed clustered QoS routing protocol CQRP increases throughput, delivery rate and network efficiency, and decreases the drop rate, delay and routing overhead.
