Role and Interval Changing Algorithm (RICA) for Energy Consumption Node in Wireless Sensor Network

A node in a network lost its energy and goes to dead state due to high transmission rate, high sensing interval rate and acting as an intermediate node. Network lifetime will be minimized very quickly. To improve energy efficiency of a node in a network, and to save a node from dead state, we proposed a Role and Interval Changing Algorithm (RICA). This algorithm will saves node's energy and avoid the node's dead state. Based on the energy level, a node will change its behaviour and control its interval rate also. If energy of a node goes below a certain specified threshold level then that node will change its role from intermediate node to leaf node and adjust its interval rate.
