Sensor networks are inherently communication-centric systems. The sensor nodes form wireless networks through which sensor readings can be transported or where nodes can act directly on data communicated from their neighbours. For sensor nodes to build networks, they need network protocols. The network protocols define the sequence of steps for the nodes to take…
