Energy-Efficient Multicasting Framework in Wireless Ad hoc Networks
- Part of Adaptive Middleware Services for Situation-Aware Communication in Ubiquitous Computing Environments

Context-Awareness Ephemeral Group Communication

Goal

A lot of applications in Wireless Ad hoc Networks (WANETs) require disseminating information to a group of hosts, e.g. data acquisition, distributed games, replicated file systems and teleconferencing. Multicasting is one of the most important group communication primitive to achieve transparency, greater efficiency and concurrence. However, wireless devices in Wireless Ad hoc Networks (WANETs) have serious resource constrains, such as on battery and bandwidth. Thus energy-efficient multicasting is an important problem in WANETs.

We are studying the problem of energy-efficient multicasting problem with application QoS constraints (e.g. delay and reliability) and dynamic environments (e.g. mobility and interference).

Energy-Efficient Multicast Framework

The framework present the conceptual model to develop energy-efficient multicasting protocols in wireless ad hoc networks.
  • Energy Cost Model: nature of wireless transceivers (long range or short range radios)
  • Node Cost Computation: QoS constraints (delay), optimization goals (TEC, LT), type of multicast trees (source-based, group-shared)
  • Cross layer design: combine network layer and link layer

We have developed three distributed protocols based on this framework.
