A New Protocol for Power Saving in Mobile Ad Hoc Networks
Main Article Content
Abstract
For mobile ad hoc networks (MANET) optimization of energy consumption has greater impact as it corresponds directly to lifetime of
a network. A Mobile Ad Hoc network (MANET) is a collection of digital data terminals that can communicate with one another without any
fixed networking infrastructure. Since the nodes in a MANET are mobile, the routing and power management become critical issues. Due to the
slow advancement in battery technology, battery power continues to be a constrained resource and so power management in wireless networks
remains to be an important issue. Power conservation in wireless ad hoc networks is a critical issue as energy resources are limited at the
electronic devices used. Power-aware routing protocols are essentially route selection strategies built on existing ad hoc routing protocols. A
survey is conducted on a series of power-aware routing protocols around energy efficient metrics. Among which, Conditional Maximum
Residual Packet Capacity (CMRPC) Protocol most comprehensively captures tradeoffs of network lifetime, energy efficiency and reliability in
packet delivery. CMRPC is simulated using NS-2 to analyze its performance gains. Through this study, we lay a foundation for further research
on enhancements in extending the operational lifetime of an ad hoc wireless network.
