摘要：MOBILE ad hoc networks (MANETs) have attracted a lot of attention due to the popularity of mobile devices and the advances in wireless communication technologies. A MANET is a peertopeer multi hop mobile wireless network that has neither a fixed infrastructure nor a central server. Every node in a MANET acts as a router, and communicates with each other. The mobility and resource constraints of mobile nodes may lead to network partitioning or performance degradation. From literature we can observe several data replication techniques have been proposed to minimize performance degradation. In which most of them assume that all mobile nodes collaborate fully in terms of sharing their memory space. But in reality, however, some nodes may selfishly decide only to cooperate partially, or not at all, with other nodes. These kinds of selfish nodes could then reduce the overall data accessibility in the network. Due to such problem the overall process of MANET got affected. In this work, we examine the impact of selfish nodes in a mobile ad hoc network from the perspective of replica allocation. We name this as selfish replica allocation. This work was motivated by the fact that a selfish replica allocation could lead to overall poor MANET data accessibility. The strategies are inspired by the realworld observations in economics in terms of credit risk and in human friendship management in terms of choosing one’s friends completely at one’s own circumspection. The notion of credit risk from economics is to detect nodes that behave selfishly. Each and every node in a MANET calculates credit risk information on other connected nodes individually to measure the degree of selfishness. The following work is analysis over the selfish node detection mechanism available in literature.
