1.4.2 Characteristics of Mobile Networks
ОглавлениеA few important characteristics of a mobile network are the following:
Dynamic topologies: Since systems can be moved subjectively, the system topology may change capriciously.
Bandwidth constrained, variable capacity links: Connecting wireless devices all together brings down connection limits compared with their wired alternative. Likewise, because of issues, for example, multi-access, fading, commotion and impedance conditions, the data transfer capacity of the remote connections can change discretionarily with time.
Energy constrained operation: The nodes in a MANET rely on battery power source. Mobile node batteries are small and normally store a very limited amount of energy. Inefficient network operations, such as routing, network initialization, etc., can rapidly drain batteries. In this situation, the most essential basic system paradigm should be vitality preservation.
Limited physical security: Mobile networks are prone to many more types of security threats than fixed networks, mainly due to wireless transmissions and collaborative routing. There are increased possibilities of eavesdropping, spoofing, and DOS attacks in these networks. Also, nodes are vulnerable to capture and compromise.
