SAR protocol based secure data aggregation in wireless sensor network

Wireless sensor networks are emerging as broadband communication networks, because of their bandwidth, low cost and easy installation. In large sensor networks, data aggregation significantly reduces the amount of communication and energy consumption in the network. In this paper two different routing protocols namely Ad hoc On-demand Distance Vector (AODV) routing protocol and Secure-aware Ad hoc Routing Protocol (SAR) are proposed. By using these protocols the network performances are evaluated in the presence of three types of attacks namely black hole attack, warm hole attack and grey hole attack respectively. The performance of the network is analyzed using the Network Simulator.
