Effect of Selfish Attack and Prevention Scheme on TCP and UDP in MANET
Mobile ad-hoc networks are a collection of mobile hosts that communicate with each other without any infrastructure and centralized administration. Due to security vulnerabilities of the routing protocols, Mobile ad hoc networks may be unprotected against attacks by the malicious nodes. One of these attacks is the selfish attack against network integrity absorbing all routing packets as well as data packets in the network. Since the data packets do not reach the destination by that due to this attack, intense data loss will occur. The damage will be serious if malicious node in a network working as an attacker node absorbs all data packets and routing packets delivered through them.
