Abstract: A wireless sensor network (WSN) is a network that is made of hundreds or thousands of sensor nodes which are densely deployed in environment with the capabilities of sensing; wireless communications and computations. WSN have constraints on the nodes such as Memory; small-size; low-power consumption; fault-tolerance and scalability which has to be addressed in order to communicate between the nodes network. In source based approaches; as the network size increases the packet size is elongated and causes overhead of processor in the node where as in location based; it requires computation at every forwarding node in a path while looking for the next forwarding node resulting in excessive processing. An Energy Efficient location aware source multicast cluster based approach for Wireless Sensor Networks is proposed. First; based on the geographic location information clusters are formed. Then; multicast tree is constructed from different sources to the sink to obtain all the possible paths. The proposed approach focuses on lowering the initial network topology; by reducing the number of active nodes and links; thus saving resources and increase the network lifetime.
