A Distributed Approach for Neighbor Position Verification in MANETs
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 9
Abstract
Mobile Ad Hoc Network(MANET) is a kind of wireless network where you can find number of base stations which supports the communication of mobile nodes. The mobile node supports the routing process of the communication to improve the throughput of the overall network. The mobile nodes are moving at some speed and towards the direction, which makes the topology of the wireless network gets changing at every fraction of time. Due to this reason there will be number of nodes comes into the coverage area of a base station and leaves, which cannot be trusted for service handling. What the adversary does here is that it replies with the route discovery phase using fake location information with the intension to get participate in the routing process. After gets selected it simply discard the packets received, or manipulate the packets, or else it will never receive the packets because of the false location. This makes the transmission as a failure one and service throughput degrades automatically. Location Based Services are one, which is provided and accessed based on the location content. In a road traffic network the location based service can be accessed in various ways. The routing in the road network becomes more complicated due to the increase in mobile nodes. A mobile node can access a service to know about the traffic and the route to reach a destination by accessing the location based service. The correctness of the node locations is therefore an all important issue in mobile networks, and it becomes particularly challenging in the presence of adversaries aiming at harming the system. This paper presents a protocol for updating the position of the node in dynamic mobile ad hoc networks. The protocol adapts quickly to position changes when node movement is frequent, yet requires little or no overhead during the periods in which hosts move less frequently
