Blackhole Prevention Algorithms for AODV in Mobile Ad Hoc Network- A Review
Devottam Gaurav, Charu Wahi · 2015
A Wireless ad-hoc network is a temporary network where several mobile autonomous nodes can move freely in any direction. With the help of routing protocols source node finds a path to the destination node and forward data packets through intermediate nodes connected by symmetrical transmitted links. However, due to mobility and ad-hoc nature, security becomes an important issue in MANET because once malicious nodes are in the range of networks; they can join the network freely and degrades the performance by attacking it. The vulnerability of MANET is very high towards routing attacks such as blackhole, which drops all the packets instead of forwarding it to the destined node and results in data loss. This research paper focuses on analyzing the probable solutions pointed out by several eminent researchers to reduce the effects of blackhole attack in MANET.
