The goal of the wireless sensor network is to deliver the desired QoS while supporting the long life the network. LEACH is one of the important and most discussed protocols in this area. The LEACH protocol works in phases wherein the set-up phase, the cluster head and the associated member nodes are finalized. Then a TDMA schedule is prepared for data transfer. In this paper, the authors have proposed two approaches to adjust the TDMA schedule depending upon the current situation thereby enhancing the quality of the WSN. The results are supported through simulation in Matlab.
