An optimized bandwidth allocation scheme in relay node for concentrated WSNs

Abstract

In a low time to live based wireless network, the node drops all its energy before actually transferring the data given to it. This serves as a drawback where the data is not transferred completely resulting in bandwidth wastage and improper message delivery. To address this problem we formulate new routing techniques by which the data from one part is scheduled to reach the destination based on the computed time to live and available bandwidth. Other than forming a routing tree which may fail when overhearing occurs, split the data and place them into appropriate bandwidths where the bandwidth wastage is minimal. Therefore the process is divided into two steps: Identifying the throughput and the mean bandwidth, initiate the data such that a least amount of bandwidth is wasted. In this method, the routing must be updated every six sees, with respect to the time to live (computed) of the node. The node energy is the tedious process which can be further enhanced by controlling the node between active and sleep state. The problems of link failure, denial of service can be rectified in this process.
