Self-Organization in MANETs
Self-Organization in MANETs
· Maintain the structure when topological changes occur: node failure, node motion, or link failure
Our next topic is self-organizing behavior of wireless ad hoc networks. Self-organization concerns organizing a set of mobile nodes with unique identifiers and wireless medium of communication into a connected network; which is able to do things like self-configure or self-organize. It concerns maintaining the structure when the topological changes occur for instance with respect to node failure, node motion or link failure.
What is Self-Organization
What is Self-Organization
· Self-Organization - Important concept in building scalable systems made up of a large number of subsystems.
· Primary Objectives of Self-Organization
Self-organization is very important in building scalable systems, particularly systems such as MANETs which are decentralized, and which is composed of typically large number of subsystems. The primary objectives of self-organization include coordination and collaboration to achieve shared goal, achieving collaboration without central entity, and improving or ensuring the reliability, the scalability and availability of the system.
So, availability is all about probabilistically ensuring that as per the SLA the system will be made available to the users for a certain duration of time. Scalability concerns that how the system would scale up, how the system is going to perform when the number of nodes in the MANET, in the case of MANETs, when the number of nodes in the system is going to increase. And reliability is all about probabilistically ensuring that the system is overall going to behave reliably at all durations of time when it is supposed to operate. So, there are different design goals of self-organization in MANETs with respect to neighbor discovery, topology configuration and topology maintenance. So, we are going to talk about each of these in more detail later on.
