In recent era, Wireless Sensor Networks (WSNs) are playing a vital role in communication world. WSNs are placed in hostile environments where many critical aspects are to be considered-energy efficiency, robustness, performance and lifetime of the network. WSNs with homogeneous sensors will not attain a great performance due to their equal capabilities, they tend to discharge all at the same time, with this life time of the network is shortened. Heterogeneous sensor networks model addresses above issues. In HSN's routing the data with security is important.
