Distributed cache updating for the dynamic source routing protocol ieee liefde gratis dating latvija
Price-based schemes treat packet forwarding services as transactions that can be paid for and introduce virtual benefits as a form of rewards to those nodes that have been participating in packet forwarding activities.This means that nodes obtain virtual credits in exchange of offering packet forwarding.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.The methodologies used to validate our proposal are as follows:.In the following, we present some representative works related to each category.It is worth mentioning that the presence of just a few number of selfish nodes could severely degrade the MANET performance [In this paper, we aim to enhance the overall performance of MANETs in the presence of selfish nodes by designing an efficient and dynamic reputation-based algorithm to be used in any ad hoc routing protocol.
In our proposal, each node locally assigns a reputation value to the rest of the nodes in the network and next it uses the assigned reputation values to find out the better routing paths, in order to minimize the overall packet loss ratio.
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.
