Vampire Bat Inspired Energy Efficient Protocol for Heterogeneous Wireless Sensor Networks

The paper provides an energy-efficient protocol for heterogeneous wireless sensor networks that was inspired by vampire bats (VB). VB uses strategic deployment in heterogeneous network which consists of Vampire nodes, cluster heads, and dependent nodes are the three different sorts of nodes. Cluster heads are positioned across the network and have been given the most energy possible since it is taken into account that nodes close to the base station spend more energy because they must serve as both data originators and data routers. As we know, normal nodes which aren't given any special extra energy are the first ones to die out. So, in order to increase the stability period, when a node's energy goes below a certain level, it is associated with a nearby vampire node to increase the energy of the dependent node, as now it won't participate in direct long-distance communication with the nearby cluster head node. The results from the simulation of the protocol showcase more proficient behavior in terms of network lifetime, network stability and throughput for VB based energy efficient protocol with respect to similar protocols available in literature.
