A Wireless Sensor Network (WSN) is composed of sensor nodes spread over the field to sense the data.


The sensed data must be gathered & transmitted to Base Station (BS) for end user queries. The used


sensor nodes being in- expensive having low computation power & limited energy so are not as much


reliable as their expensive macro sensor counter parts but their size and cost enable hundred to thousand


of micro sensors to achieve high quality fault tolerant system. In an environment where in each round all


sensor nodes have to send data to base station, it is required to effectively utilize energy of sensor nodes


so as to increase the life- time of the system. The use of data aggregation & fusion as proposed in LEACH


increases system lifetime by a factor of 8 as compared to conventional routing protocols. In this paper


along with data aggregation & fusion, we are trying to minimize reduction in system energy by first


generating MST between all sensor nodes so as to minimize their transmission energy with in network


and after that a node of highest energy among the top tier will transmit the aggregated data of whole


network to base station. Keeping network topology same till any node of network dies another highest


energy node from top most rank tier is chosen to communicate with BS. This technique achieves 10x to


20x improvement in system life time as compare to MTP.
