Reliable Data Aggregation Protocol for Wireless Sensor Networks

Current routing protocols in WSNs or even in Wireless Ad hoc Networks are very susceptible to many attack i.e. stealthy attack. The most simple among those is where the adversary injects malicious routing information into the network. This results in routing inconsistencies leading to high increase in end-to-end delays or even packet losses in the network. In our paper, first, we abstract two fundamental routing protocols, which can be generally grouped in two broad categories based on the intrinsic nature of WSN. We argue that none of previous proposed routing protocols satisfies all of them at the same time. The novelty of our protocol is building a general routing protocol based on two methods, which takes into consideration two factors, first additional of sensor nodes to the aggregation process and second by considering complex report interaction between base station and aggregator. Finally, to evaluate the efficiency and effectiveness of the proposed protocol, we carry out comparison experiment of our proposed protocol to general known protocols. Performance cost evaluation of our proposed protocol shows essential advantage over existing protocol.
