Evaluation of Performance of Ciphers for Routing Protocols in Distributed Sensor Networks

With recent advances in communication technologies, Distributed Sensor Network (DSN)s are widely deployed for many applications such as military, bank transactions and healthcare. These sensor nodes are equipped with lesser memory, limited battery power, little computation capability, small range of communication and then need a secured and efficient routing algorithm to forward incoming packets. In this paper, two routing algorithms Viz., FLAT and HIERARCHICAL are compared with respect to energy consumption and security features in transmission of data from a source to a destination and for providing security services like confidentiality. The ciphers considered for performance analysis are symmetric (RC5), and asymmetric (ElGamal, RSA and ECC) algorithms
