Secure Energy Aware Anonymous Location Based Routing Protocol Formanet

In order to provide randomized routing ALERT (Anonymous Location-based and Efficient Routing) protocol is used. But the proposed protocol SEALERT will provide higher anonymity protection at lower cost. It also increases the nodal lifetime in the network. Thereby it increases the efficiency of transmission of packets. The proposed protocol dynamically partitions the network into area called zones and it randomly chooses a node as an intermediate relay node. This node forms a non-traceable anonymous route. Later this relay node chooses another node in the network which has least cost from the destination. The process of choosing relay node takes place until the destination can be reached at lower cost. Each time for choosing another node it uses EGPRS algorithm, a variant of GPRS (used in SEALERT to send data to relay node), to find a node with inherent battery backup. Since the data is broadcasted to k nodes in the destination zone, it can provide k-anonymity for the destination. The proposed also detects the Sybil attack in the network.
