A Comparitive Learning on Wormhole Attack and Black Hole Attack

Network is the open platform where the people share and communicate with each other. Also, the open source will create a majority of problems. Whenever the data or the information's are need to be transferred from one place to another (i.e) from source to destination it has to be protected by any algorithm in the name of security. Otherwise the data will be hacked by any attackers’ namely active attacks or by passive attacks. Wormhole attacks can destabilize or disable wireless sensor networks. In a typical wormhole attack, the attacker receives packets at one point in the network, forwards them through a wired or wireless link with less latency than the network links, and relays them to another point in the network. At that time hacker may easily enter and do misuse inside the network. Also, the Black hole attacks occur when an adversary captures and re-programs a set of nodes in the network to block/drop the packets they receive/generate instead of forwarding them towards the base station. As a result any information that enters the black hole region is captured. Black hole attacks are easy to constitute, and they are capable of undermining network effectiveness by partitioning the network, such that important event information do not reach the base stations. In this paper we have analyzed the warm hole attack and the black hole attack and their comparative study of the attacks.
