摘要：In a low TTL based wireless network, the node drops all its energy before actually transferring the datagiven to it. This serves as a drawback where the data is not transferred completely resulting in bandwidth wastage andimproper message delivery. To address this problem we formulate new routing techniques by which the data from onepart is scheduled to reach the destination based on the computed TTL and available bandwidth. Other than forming arouting tree which may fail when overhearing occurs, RSF splits the data and places them into appropriate bandwidthswhere the bandwidth wastage is least. Therefore the process is of two steps: Identify the throughput and the meanbandwidth, place the data such that a least amount of bandwidth is wasted. Choosing an appropriate node that handlesthe incoming bandwidth is tedious and hence requires a bandwidth and energy allocation strategy for successfulhandling of node switching. Energy efficient node allocation can be done using least possible chance of fading of anode. The condition is achieved my observing the Tx and Rx of the nodes, in a scenario.
