Distributed cache updating for the dynamic source routing protocol ieee who is luann de lesseps ex husband dating
The paper  proposes a stimulation mechanism based on a counter in each MANET node.
The counter increases when the node forwards packets for others and decreases, following a function that depends on the estimated hop count to destination, when the node sends its own packets.
It is out of the scope of the proposal to define any mechanism to reward or penalize the nodes of the network in order to force their cooperation.
Actually, our approach consists in a reputation-based forwarding strategy for ad hoc routing protocols that avoid using forwarding paths that include selfish nodes that would not forward packets properly.
The methodologies used to validate our proposal are as follows:.
In the following, we present some representative works related to each category.
The presence of selfish nodes that do not cooperate in this task drastically reduces the number of delivered packets.
A micro-payment scheme for multi-hop cellular networks is presented in  to encourage collaboration in packet forwarding by letting users benefit from relaying others’ packets.
Also, they propose mechanisms for detecting and rewarding collaboration, while detecting and punishing cheating.
Thus, the quality of service offered to the user improves.
includes our methodology to average the reputation forwarding values of the nodes, using a cumulative moving average (CMA) to average the reputation samples, and an exponentially weighted moving average (EWMA) to detect behavioral changes in the nodes.
