Implementation of Span-AODV Approach for Best-Energy Path and Enhancement of Lifetime in Caterpillar Network


Wireless Sensor Networks (WSNs) have been mostly considered with improvements in ubiquitous computing environment. The supply of a sensor node is limited, so it is essential to use energy-efficient routing protocol in WSNs. Energy consumption can be maintained to certain threshold level, so that no individual nodes can go dry beyond that certain level. Here we suggest each node to behave active and idle states, so that average energy level of whole network can be maintained. In SPAN-AODV protocol, we will compute the procedure to identify the nodes, which losing its energy earlier than other. We isolate those nodes below threshold energy from communication. Packet transmission has done only through energy nodes, even non-energy nodes present at accessible distance to communicate. In this paper we compare SPAN-AODV, EDDEEC (Enhanced Developed Distributed Energy-Efficient Clustering) and CATER-AODV (SPAN-AODV implemented in caterpillar network) through performance analysis and the result shows that CATER-AODV is 21% more efficient than EDDEEC and 17% more efficient than SPAN-AODV in terms of residual energy, network lifetime and traffic size.
