Secured Routing Using ALERT in MANETs

The routing protocol depends on either hop-by-hop routing table which generates high cost and also unable to provide full anonymity protection to data sources, destinations and routes. So as to provide high anonymity protection at low cost in MANETs (Mobile Ad-hoc Networks), ALERT (Anonymous Location-Based Efficient Routing Protocol) routing protocol can be used. In the ALERT protocol, it partitions the network into zones which randomly chooses nodes as intermediate relay nodes. It also hides the data receiver or initiator between many receivers to strengthen source and destination anonymity protection. Thus it provides Anonymity Protection to sources, destinations and routes. ALERT also achieves comparable routing efficiency to base-line GPSR (Greedy Perimeter Stateless Routing) algorithm.
