Abstract: Wireless sensor networks consist of some nodes that have limited processing capability, small memory and low energy source. These nodes are deployed randomly and often densely in the environment. In monitoring applications, sensor nodes sense data from the environment periodically and then transmit them to a base station which is called sink node. Thereby, data transmission consumes node ’s energy based on transmission distance. In most wireless sensor networks, the energy source of the node is limited and can not be minimized. Here, researchers have proposed the Efficient Multipath Routing Tree based Energy Minimization (EMRTEM) for minimizing the energy consumption in WSNs. It consists of three phases. These phases are the Tree selection phase, multipath routing tree determination and Minimizing Average Energy Consumption Model. The proposed scheme which attains the balance route minimum cost, route redundancy and energy efficiency in WSNs. By simulation results, the proposed EMRTEM achieves better data delivery ratio, improved network lifetime, less end to delay and energy consumption in terms of mobility, time, throughput, packet interval and number of nodes than the existing scheme ADAPT.
