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.
