摘要:Energy conservation is most important issue prevailing in various real world systems. Wireless sensor networks (WSNs) also suffer with this difficulty as the sensor nodes deployed in the regions being monitored cannot be re-energized. Thus, it is required to attain higher performance of systems while lowering the cost in terms of energy. We have proposed new n-Level Tree-based Routing Approach (NLTRA) for data routing for homogenous as well as heterogeneous WSNs in order to meet the system requirements. Mathematical modeling has been done for the distribution of residual energy among the sensor nodes of the network using normal distribution. A graph theory based approach is employed for the representation of network as a set of nodes and edges. A tree based path is determined for data routing in the network. The hierarchy is maintained on the basis of energy levels of sensor nodes and the optimal spanning tree (OST) is obtained.
