MINIMIZING LOCALIZATION ERROR AND ENSURE SECURITY OF DVHOP APPROACH

In case of wireless sensor network there exist problem of determining the nodes which are symmetrical to each other. The nodes which are symmetrical and are at lesser distance are selected for data transfer. This identification of the distance between nodes is known as localization. In the proposed paper work on DVHOP is done. The DVHOP is the distance vector routing based protocol which is used to indicate whether there exist a path from source to destination or not. The malicious node can also be present which can take over the actual node causing problems in the transfer process. The most common attack which results from this will be DDOS attack. This will result in the duplication of the information and will cause traffic jamming. DVHOP with random key is used to handle DDOS attack.
