Summary Trust is considered as the most significant factor that helps in enforcing cooperation among the autonomous nodes of Mobile Ad hoc Network (MANETs). The computation of trust is essential for assessing the level of cooperation rendered by each individual mobile toward the activity of data routing. The calculation of trust in a self‐configuring and infrastructure‐less network is a challenge due to the dynamic movement of mobile nodes. Moreover, the trust of intermediate nodes in the routing path needs to be estimated for preventing the deterioration of network performance. In this paper, a Fuzzy COPRAS‐based Node Cooperation Enforcing Trust Estimation (FCOPRAS‐NCETE) Scheme was proposed for maintaining superior Quality of Service (QoS) in the event of reliable data dissemination. This proposed FCOPRAS‐NCETE Scheme was proposed for comprehensive ranking of mobile nodes acting as intermediate nodes between the source and destination nodes. It incorporated the benefits of fuzzy set theory and COmplex PRoportional ASsessment of alternatives (COPRAS) to determine the trust of intermediate nodes for isolating them from the routing path in the uncertain routing process with the objective to maintain superior QoS in the network. The simulation experiments of the proposed FCOPRAS‐NCETE Scheme conducted using ns‐2 confirmed its predominance in improving the throughput, packet dissemination rate, packet loss rate, energy consumptions and total overhead with different number of mobile nodes, CBR traffic rate and pairs of source and destination nodes in the network.

“…Yet another, novel method for mitigating selfish through second hand reputation mechanism based on split half reliability coefficient was proposed by Sengathir and Manoharan [21].This mechanism estimates the nodes' behaviour with regard to two perspectives viz, packet delivery rate of a mobile node and packet forwarding ability of a mobile node. The split half reliability coefficient is derived based on Karl Pearson correlation coefficient and spearman brown formula that interprets the change in the level of nodes' behaviour from its normal routing activity.…”

In mobile ad hoc networks, cooperation among active mobile nodes is considered to play a vital role in reliable transmission of data. But, the selfish mobile nodes present in an ad hoc environment refuse to forward neighbouring nodes' packet for conserving its own energy. This intentional selfish behaviour drastically reduces the degree of cooperation maintained between the mobile nodes. Hence, a need arises for devising an effective mechanism which incorporates both energy efficiency and reputation into account for mitigating selfish behaviour in MANETs. In this paper, we propose an Exponential Reliability Coefficient based reputation Mechanism (ERCRM) which isolates the selfish nodes from the routing path based on Exponential Reliability Coefficient (ExRC). This reliability coefficient manipulated through exponential failure rate based on moving average method highlights the most recent past behaviour of the mobile nodes for quantifying its genuineness. From the simulation results, it is evident that, the proposed ERCRM approach outperforms the existing Packet Conservation Monitoring Algorithm (PCMA) and Spilt Half Reliability Coefficient based Mathematical Model (SHRCM) in terms of performance evaluation metrics such as packet delivery ratio, throughput, total overhead and control overhead. Further, this ERCRM mechanism has a successful rate of 28% in isolating the selfish nodes from the routing path. Furthermore, it also aids in framing the exponential threshold point of detection as 0.4, where a maximum number of selfish nodes are identified when compared to the existing models available in the literature.

“…The most commonly used tests of internal consistency reliability are Split-half reliability (Wagner & Flamos, 1988) and Cronbach's alpha (Cronbach, 1971;de Vet et al, 2017;Leppink & Pérez-Fuster, 2017). Kuder-Richardson 20 is also used, but it is essentially a restricted version of Cronbach's alpha (Sengathir & Manoharan, 2013).…”

Entrepreneurs are the backbone of the U.S. economy and their small businesses represent the primary job source forAmerican workers. Research exists on small business at a national and an international scale but a limited amountof region specific information exists in the literature. The purpose of the research is to explore the relationshipbetween social capital and the failure or success of entrepreneurs who own businesses in Beckley, West Virginia, asmall Appalachian town. The theoretical framework for this study is social exchange theory. This qualitative studyused interpretive phenomenological analysis as the chosen research design because of the capability to query theirlived experiences. The purposive sampling method was used. The twelve participants were divided into two groupsconsisting of failed businesses and successful businesses. The successful business has existed for more than five years.The failed business opened within the past five years but has closed. The answers provided by the participants addressed the problem of the high fail rate of small businesses in Appalachia. The findings of the study are importantbecause the application of social exchanges by entrepreneurs was shown to increase the longevity of small businesses.
