Wireless Sensor Networks is the area where researches are being done mostly because of two reasons. One is due to its importance in various sectors and another is due to its constraints in its use. These WSN’s has limitations in battery, and emitting frequency in high. Mostly the people who perform their research only assume of a single WSN in an area, but in reality we can see may multi WSN’s at the same place. The WSN’s installed at a same place, which has its own applications running on them and we can call them as heterogeneous networks. Because of this, sensor nodes mingled with the other networks, sensor nodes of one WSN are prone to collisions with the other networks. To overcome the above situation we are going to introduce some nodes called mutual nodes which brings the cooperation between the WSN’s and a life node in every WSN which enhances the network life time and reduces the load. © 2017, Institute of Advanced Scientific Research, Inc.
