ABSTRACT We introduce one or a few shared nodes that can use multiple channels to relay data packets. Assuming that sinks and shared nodes can communicate with any WSNs here, different WSNs can use cooperative routing with each other since shared nodes allow sensor nodes to forward data from another WSN as the function of interchange points among respective WSN planes. When receiving a packet, a shared node selects the route to send the packet, according to proposed route selection methods. This cooperation prolongs the life time of each network equally as possible. Keywords- Sensor Network, Cooperative Routing, Fairness, Heterogeneous Environment, Load Balancing. INTRODUCTION Wireless Sensor Network (WSN) is a distribution of autonomous sensors, which cooperatively monitor physical or environmental conditions, such as temperature, vibration, pressure, sound and so on. WSNs are used in many areas, including home automation, health monitoring or other healthcare applications, industrial process control and monitoring, etc. IJCSCN | October-November 2017 Available online@ Applications of WSNs are expanding and the implementation of multifunctional and reliable WSNs is of utmost importance. The detection process in WSNs mostly depends on sensor node’s physical conditions and the solutions of detection problems are largely based on hardware rather than software. After detection, the node has to find whom and how to transfer the sensed data.
