Fair Routing for Overlapped Cooperative Heterogeneous WSN’s

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 lifetime ofeach network equally as possible.
