Abstract :
We propose an efficient method to re-allocate resources available on Mobile Ad-hoc Networks in the event of a network attack or a node failure. By utilizing a structure we call a resource fitness cache, we identify a way to reduce the number of messages required to find a suitable replacement resource among remaining nodes on the network, assuming that redundancy is present in among the resources. Our approach employs an arbitrator node that triggers the allocation. The arbitrator is chosen based on which node first needs access to a resource that has become unavailable. Initial results show a 40-74% improvement in densely-connected networks, versus the baseline un-cached case. Our results were generated using the Omnet++ 4.0 discrete event network simulator.
