Mobility Assisted Uncertainty Reduction in MANETS Using Forward Node Optimization

Abstract

Abstract A mobility-assisted scheme called efficient flooding scheme is provided to achieve the high probability of trust convergence. Trust will be defined as the belief in the capability of an entity (node) to proceed reliably, securely and dependably within a specified context. It represents a MANET participant's hope of other nodes’ behavior while assessing the risk involved in future interactions. Here, the participant, called the trustor, and other nodes are said to be trustee. The trust relationship usually builds on the basis of the trust or's past direct interaction experiences and others’ recommendations related to the trustee. The abstracted value from precedent experiences and from recommendations is defined as the trustee's reputation. The proposed mobility assisted scheme, an efficient flooding scheme which is based on node's mobility. The efficient flooding scheme is based on one-hop neighbor that leads to reduction of number of forwarding nodes. This scheme offers a handy tradeoff between delay, cost, packet delivery and trust ratio which leads to uncertainty reduction.
