Improving ZRP Protocol against Blackhole Attack

  Chaitas Shaha,  Prof. Manoj Patel

In Mobile Ad-Hoc Network different types of routing protocols have been discovered. These protocols can be classified into three main categories reactive (on-demand) Ad-hoc On Demand Routing Protocol (AODV), proactive (table-driven) OLSR and hybrid routing protocol Zone Routing protocol (ZRP). Thus routing protocols for Mobile Ad-Hoc Network have to face the challenge of frequently low transmission power, asymmetric links and changing topology. Both proactive and reactive routing protocols prove to be inefficient certain circumstances. The hybrid protocol Zone Routing Protocol (ZRP) combines the advantages of the proactive and reactive approaches and it maintains an updated topological map of a zone centered on each node in the network. Within the zone, routes are immediately available for transmission of packets. Thus for destinations outside the zone, Zone Routing Protocol employs a route discovery procedure, which benefits from the local routing information of the zones. However, due to security vulnerabilities of routing protocols and wireless networks remains unprotected to attacks of the different malicious nodes. One of attacks is the Black hole Attack against network integrity absorbing all data packets in the network. The detection techniques that make use of proactive routing protocol they have better packet delivery ratio and correct detection probability but they have high overheads. The detection techniques which make use of reactive routing protocols have low overheads, but they have high packet loss problem. Therefore in this paper using a hybrid detection technique which combines the advantages of both reactive and proactive routing protocol to detect the black hole node and removing it.
