In a low TTL 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 TTL and available bandwidth. Other than forming a routing tree which may fail when overhearing occurs, RSF splits the data and places them into appropriate bandwidths where the bandwidth wastage is least. Therefore the process is of two steps: Identify the throughput and the mean bandwidth, place the data such that a least amount of bandwidth is wasted. Choosing an appropriate node that handles the incoming bandwidth is tedious and hence requires a bandwidth and energy allocation strategy for successful handling of node switching. Energy efficient node allocation can be done using least possible chance of fading of a node. The condition is achieved my observing the Tx and Rx of the nodes, in a scenario.
