Diagnosis of static Topology MANETs in faulty environment

Samantaray, Subhadeep and Mishra, Nayan Jyoti (2011) Diagnosis of static Topology MANETs in faulty environment. BTech thesis.



Mobile Ad-Hoc Networks (MANETs) are set of mobile nodes that communicates wirelessly without a centralized supporting system. Faulty nodes aect the reliable
transmission of messages across the network. In this thesis we deal with the fault identication problem in static topology MANETs. A comparison based approach is used where a set of tasks is given to the nodes and outcomes are compared. Based on these comparisons the nodes are classied either as faulty or fault free. Our new diagnosis model is based on the spanning tree concept in which the testing of the nodes as well as the construction of the spanning tree takes place simultaneously. As a result of which the maintenance and the repairing overhead of the spanning tree is completely avoided thus reducing the number of messages exchanged. We have also developed a simulator which can be applied to a network with large number of nodes.We have carried out the simulation in-order to nd out the total number of messages exchanged and the total diagnosis time. On analysing the results we have seen that our model performs better than its previous counterparts. The correctness and complexity proofs are also being provided which also shows that our model performs better from
a communication as well as latency viewpoint.
