Secured Demand Routing for Mobile is a communication protocol and network routing approach designed to enhance the security and efficiency of data transmission in mobile ad hoc networks (MANETs). MANETs are decentralized networks formed by mobile devices, such as smartphones, laptops, and tablets, that communicate with each other directly, without the need for a fixed infrastructure.In a mobile ad hoc network, securing data transmission is essential due to the dynamic nature of the network and the potential for malicious nodes or eavesdroppers to intercept or tamper with the data. Secured Demand Routing (SDR) aims to address these security challenges while optimizing data delivery in MANETs.Demand-Based Routing: SDR utilizes demand-based routing algorithms, where data packets are transmitted only when there is a specific request or demand for that data. This reduces unnecessary network traffic and improves efficiency.Authentication and Authorization: SDR incorporates robust authentication and authorization mechanisms to ensure that only authorized devices can participate in the network and access sensitive data.Encryption: Data encryption is employed to protect the confidentiality and integrity of the transmitted data, preventing unauthorized access or tampering.Secure Key Management: Efficient key management schemes are used to establish and distribute encryption keys securely among the participating nodes.Intrusion Detection and Prevention: SDR implements intrusion detection and prevention mechanisms to identify and respond to malicious activities or compromised nodes in real-time.Secure Neighbor Discovery: The protocol employs secure neighbor discovery mechanisms to identify and authenticate neighboring nodes before establishing communication links.

Absurdity 'is a metaphysical term to distinguish thought from reality, meaning from things, word from the subject and consciousness from the world. Existential philosophy is the profound explicit manifestation of an existential attitude that begins with a sense of disorientation and confiision in the face of an apparently meaningless or absurd world. An important component of existentialist philosophy is the portrayal o f existence as being fundamentally irrational. Whereas most philosophers have attempted to build philosophical systems that produce a rational account of reality, existentialists have focused upon the subjective, irrational character of human existence. As a consequence of the diversity of these sources, existentialist doctrines focus on several aspects of existence. The absurdity of our lives comes from the idea that there is no meaning to be found in the world beyond what meaning we give to it. This meaninglessness also accounts for the 'unfairness' of the world. Humanity must live in a world that is and will forever be hostile or indifferent towards them. The universe will never truly care for humanity the way we seem to want it to. The Absurd refers to the conflict between the human tendency to seek value and meaning in life and the human inability to find any. In this context absurd does not mean 'logically impossible,' but rather 'humanly impossible.' It means the discrepancy between the man's aspirations and his possibilities; the lack of any ultimate external justification of man and his projects^
