The bandwidth utilization plays a vital role in a Wireless Sensor Network (WSN) that transmits data packets from source peer to perspective destination peer without any packet loss and time delay. In a conventional system, two main features cannot be satisfied concurrently such as low delay and high data reliability and then the peer was transferred fewer data packets and it optimized with regular bandwidth rate. Moreover, the convention of bandwidth in network routers influences the quality of

... service (QoS). To overcome the above issues, an Efficient Reliability and Interval Discrepant Routing (ERIDR) algorithm is proposed to optimize bandwidth utilization on the router network with the help of bandwidth optimizer. The bandwidth optimizer allocates required bandwidth for data transmission to each peer simultaneously to ensure the bandwidth efficiency.
