Characteristics of MANETs

  • ·     In MANET, each node act as both host and router. That is it is autonomous in behavior. 
  • ·     Multi-hop radio relaying- When a source node and destination node for a message is out of the radio range, the MANETs are capable of multi-hop routing.
  • ·     Distributed nature of operation for security, routing and host configuration. A centralized firewall is absent here.
  • ·     The nodes can join or leave the network anytime, making the network topology dynamic in nature.
  • ·     Mobile nodes are characterized with less memory, power and light weight features.
  • ·     The reliability, efficiency, stability and capacity of wireless links are often inferior when compared with wired links. This shows the fluctuating link bandwidth of wireless links.
  • ·     Mobile and spontaneous behavior which demands minimum human intervention to configure the network.
  • ·     All nodes have identical features with similar responsibilities and capabilities and hence it forms a completely symmetric environment.
  • ·     High user density and large level of user mobility.
  • ·     Nodal connectivity is intermittent.

Client Server Computing with Adaptation

Image
Client Server Computing with Adaptation • Two adapters (adaptation software) at a mobile device • An adapter for standard data format for synchronization at the mobile-device • Another adapter for the backend database copy, which is in a different data format for the API at the mobile-device Adaptation: Software to get data in one format or data governed by one protocol and convert it to another format or to data governed by another protocol ·          Used for interchange between standard data formats and data formats for the API ·          IBM WebSphere Everyplace Access (WEA) provides adapters for synchronization objects (for example, XML format synchronization objects) and the objects of API databases (for example, for the PIM APIs)

Data Dissemination Broadcast-disk Models

Image
Data Dissemination Broadcast-disk Models: ·          Presumed that all the n records to be broadcast are stored on a circular disk from 0° to 360° ·          A hypothetical disk revolves and the angle changes from 0°to 360° ·          The entire N bits in n records get pushed through a hypothetical reading-head over the disk. ·          The head continuously reads each bit of a record just beneath it and broadcasts it instantaneously on the wireless network ·          During next revolution each bit in the records positioned from 0° to 360° broadcast once again in the same sequence as in earlier revolution Number of adaptations and algorithms for broadcast: 1. Circular Multi-disk Model 2. Flat Disk Model 3. Multi-disk Model with repetition rate proportional to priority 4. Skewed disk model Circular multi-disk model • Each block of records pushed with a repetition rate proportional to its hierarchical level Each rotating disk cycle:
