Energy based proficiency analysis of ad-hoc routing protocols in wireless sensor networks

In a densely deployed sensor node network, each sensor nodes sense data and transmit it to a particular sink through multi-hop communications. Sensor nodes deployed nearby the sink node need to convey some extra data and control packets and therefore undergo much quicker energy depletion rates and so they have considerably smaller lifespan. This may discontinue network from functioning for a long time. Herein, we have analyzed the lifetime of sensor networks by using AODV, DSR, DYMO and ZRP protocol under different node density. Network Lifetime, throughput, energy consumption analysis, Average end to end delay, work efficiency, packet delivery ratio and packet latency (jitter) of each protocol has been demonstrated. The research of the usefulness of some prevailing methodologies towards lifespan estimation of sensor network has been carried out and simulation results are used to confirm the analysis. Behavior of protocols is observed under different energy models like generic, mica-motes and micaz. ZRP protocol consumes maximum energy under generic model and least energy under Micaz model. Average energy consumption is highest for generic model. For small number of nodes jitter of DYMO is more while for large number of nodes ZRP produces maximum jitter. DYMO produces maximum end to end delay while AODV produces minimum delay. Micaz model give maximum lifetime to a network. Energy consumption in transmission and receiving is highest for generic model. Throughput, work efficiency and packet delivery ratio is highest for DSR protocol.
