sensor network is composed of a largenumber of autonomous sensor nodes, which are denselydeployed in the area of interest i.e either inside thephenomenon or very close to it. Routing is an importantoperation, being the foundation of data exchangingbetween wireless devices.Zone Routing Protocol was thefirst hybrid routing protocol with both a proactive and areactive routing component. ZRP was proposed to reducethe control overhead of proactive routing protocols anddecrease the latency caused by route discovery in reactiverouting protocols. ZRP defines a zone around each nodeconsisting of the numbers of neighbourhood. During myresearch work, I applied the hybrid routing protocol inwireless sensors and measure the correspondingperformance of the network in terms of overhead, delayand throughput.[10]
MANET is the self-configuring type of network in which the mobile nodes can leave or join the network when they want. MANET is decentralized type of network, no central controller is present. Due to their unique features mobile ad hoc networks can be deployed anywhere round the clock. This posed the remedial venture to large number of attacks like replay attack, fabrication, eavesdropping etc Kaman provides secure solution to the problem of secure channel establishment, secure exchange of session keys and prevention of nodes identity forgery. In this paper, we reviewed the Kaman; Kerberos assisted Authentication in Mobile Ad hoc Network and added the concept of timers in KAMAN to solve the problem of black hole attack that aroused when Kaman protocol is embedded into large network AODV, on-demand routing protocol had been used to select secure shortest path between the nodes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
