Network Technology Cluster - Mobile Ad Hoc Network  



"To investigate issues pertaining to infrastructure-less mobile ad hoc networks so as to provide reliable end-to-end communication at any time and anywhere. "


Power Saving Mechanisms

  • Mobiles are powered by batery with limited capacity
  • Radio transmission is very power consuming
  • Power-aware or power-efficient protocol design can significantly increase the operation time of mobiles


Scalable Routing in MANET

  • Every node maintains the link state information within the group, hence the routing table is scalable
  • Communication occurs only between group leaders, reducing the routing overheads
  • Applicable to large size networks
    Can be used in networks with high mobility

Fairness & Qos issues

To provide fairness and QoS under

  • Hidden-terminal problem in multihop scenario
  • Error and fading conditions
  • Network topology changes due to high mobility

Securing Location-based Routing

  • Routing security is an important issue
  • Most research is based on topology-based routing protocols such as DSR, AODV, etc.
  • Previous work on location-based routing assumes a trusted environment

Multicast in MANET

Our objective is to design a multicast protocol for MANET with following improvements

  • Enhanced efficiency in packet delivery
  • Adaptability to failure, mobility, partitions, etc.
  • Support for different QoS classes

Qos Through Multi-path Discovery

To address QoS-aware Routing issues such as

  • How to establish routes that meets QoS criteria?
  • How to find multiple path with node disjoint?
  • How to effectively estimate the available bandwidth and delay per hop?
