Abstract

Objectives: To develop a new multipath load sharing algorithm using channels sensing, node energy level analysis and malicious node detection. It aims at finding an efficient load sharing technique that gives better throughput delivery, less delay and security for data transformation. Methods/Analysis: A channel sensing between the nodes is performed to measure the signal to noise ratio and reject the path if the noise strength is greater than the signal strength. Prior energy level analysis is done for consistent data transmission over a period of time without any interrupt. A watchdog timer method is adopted for malicious node identification and removal. Findings: The quality of service in MANETs has been improved such as throughput has been increased 15% and packet delivery ratio has been increased 20% and the overall delay has been minimized 27%. Conclusion/Application: We proposed an efficient best path selection load sharing algorithm, which involves channel sensing, node energy level analysis and malicious node removal for security concern.

Abstract

Background/Objectives: The objective of the work carried out in this paper is to present the literature based on different Supply Chain (SC) coordination mechanisms. Also, it is intended to explore various coordination models proposed by various researchers from the literature. Methods/Statistical Analysis: The literature is reviewed by considering 142 articles published from 2000 to till date and classified as two-level models and three-level models. All these articles are further discussed based on few coordination mechanisms such as trade credit, quantity discounts, revenue sharing contract and information sharing. In addition, the literature is reviewed on Vendor Managed Inventory and price dependent demand variations and the coordination issues are discussed. Findings: From the findings of this research, it is observed that sufficient volume of papers reported the coordination mechanism in a two-level SC. The number of papers discussing three-level SC coordination is few in number. Especially, in the perspective of trade credit and quantity discount option, very few articles are reported discussing coordination in a three-level SC. Further, it is also found that most of the articles addressed the coordination mechanism incorporating ordering and carrying costs. Very few articles addressed the implications of transportation cost in SC coordination mechanism. Application/Improvement: From the outcomes of this work, it is observed that study of the effect of space cost and advertisement cost on SC performance is highly significant. The use of simulation is highly emphasized as the activities of SC are becoming highly dynamic and challenging with the ever growing global competition.
