Correct option is C
Mobile Adhoc Networks (MANETs) are a type of network where nodes are mobile and can join and leave the network at any time without the need for a fixed infrastructure. Let's examine the given features one by one:
A. Self-Organizing and decentralized: MANETs are self-organizing, meaning that the network can organize itself without the need for a central controller. The network is decentralized, and each node communicates directly with others.
B. High Mobility of nodes: The key feature of MANETs is the high mobility of nodes. These networks are designed to work in environments where nodes (such as mobile devices, vehicles, etc.) move around freely.
C. Requires fixed Infrastructure for operation: This is incorrect because MANETs do not require fixed infrastructure. One of the defining characteristics of MANETs is that they are ad-hoc networks without any centralized infrastructure or base stations.
D. Network Topology is dynamic and constantly changing: This is correct because the network topology in MANETs is dynamic. Nodes can enter or leave the network at any time, which means the topology constantly changes as nodes move.
E. It requires a central controller to manage network traffic: This is incorrect because MANETs are designed to operate without a central controller. The decentralized nature of MANETs means there is no need for a central authority to manage the network traffic.
Information Booster:
1. Self-Organizing: Nodes in MANETs automatically discover and maintain routes to other nodes without any external help.
2. High Mobility: Mobile devices such as smartphones, vehicles, and drones are common in MANETs.
3. Dynamic Topology: The structure of the network changes as nodes move, which requires routing protocols that can adapt to these changes.
